vector. It is not necessary to write special routines for these entry points when creating a new BFD back end, since generic versions are provided. However, writing them can speed up linking and make it use significantly less runtime memory. The first routine creates a hash table used by the other routines. The second routine adds the symbols from an object file to the hash table. The third routine takes all the object files and links them together to create the output file. These routines are designed so that the linker proper does not need to know anything about the symbols in the object files that it is linking. The linker merely arranges the sections as directed by the linker script and lets BFD handle the details of symbols and relocs. The second routine and third routines are passed a pointer to a @@code{struct bfd_link_info} structure (defined in @@code{bfdlink.h}) which holds information relevant to the link, including the linker hash table (which was created by the first routine) and a set of callback functions to the linker proper. The generic linker routines are in @@code{linker.c}, and use the header file @@code{genlink.h}. As of this writing, the only back ends which have implemented versions of these routines are a.out (in @@code{aoutx.h}) and ECOFF (in @@code{ecoff.c}). The a.out routines are used as examples throughout this section. @@menu * Creating a Linker Hash Table:: * Adding Symbols to the Hash Table:: * Performing the Final Link:: @@end menu @@node Creating a Linker Hash Table, Adding Symbols to the Hash Table, Linker Functions, Linker Functions @@subsection Creating a linker hash table @@cindex _bfd_link_hash_table_create in target vector @@cindex target vector (_bfd_link_hash_table_create) The linker routines must create a hash table, which must be derived from @@code{struct bfd_link_hash_table} described in @@code{bfdlink.c}. @@xref{Hash Tables}, for information on how to create a derived hash table. This entry point is called using the target vector of the linker output file. The @@code{_bfd_link_hash_table_create} entry point must allocate and initialize an instance of the desired hash table. If the back end does not require any additional information to be stored with the entries in the hash table, the entry point may simply create a @@code{struct bfd_link_hash_table}. Most likely, however, some additional information will be needed. For example, with each entry in the hash table the a.out linker keeps the index the symbol has in the final output file (this index number is used so that when doing a relocatable link the symbol index used in the output file can be quickly filled in when copying over a reloc). The a.out linker code defines the required structures and functions for a hash table derived from @@code{struct bfd_link_hash_table}. The a.out linker hash table is created by the function @@code{NAME(aout,link_hash_table_create)}; it simply allocates space for the hash table, initializes it, and returns a pointer to it. When writing the linker routines for a new back end, you will generally not know exactly which fields will be required until you have finished. You should simply create a new hash table which defines no additional fields, and then simply add fields as they become necessary. @@node Adding Symbols to the Hash Table, Performing the Final Link, Creating a Linker Hash Table, Linker Functions @@subsection Adding symbols to the hash table @@cindex _bfd_link_add_symbols in target vector @@cindex target vector (_bfd_link_add_symbols) The linker proper will call the @@code{_bfd_link_add_symbols} entry point for each object file or archive which is to be linked (typically these are the files named on the command line, but some may also come from the linker script). The entry point is responsible for examining the file. For an object file, BFD must add any relevant symbol information to the hash table. For an archive, BFD must determine which elements of the archive should be used and adding them to the link. The a.out version of this entry point is @@code{NAME(aout,link_add_symbols)}. @@menu * Differing file formats:: * Adding symbols from an object file:: * Adding symbols from an archive:: @@end menu @@node Differing file formats, Adding symbols from an object file, Adding Symbols to the Hash Table, Adding Symbols to the Hash Table @@subsubsection Differing file formats Normally all the files involved in a link will be of the same format, but it is also possible to link together different format object files, and the back end must support that. The @@code{_bfd_link_add_symbols} entry point is called via the target vector of the file to be added. This has an important consequence: the function may not assume that the hash table is the type created by the corresponding @@code{_bfd_link_hash_table_create} vector. All the @@code{_bfd_link_add_symbols} function can assume about the hash table is that it is derived from @@code{struct bfd_link_hash_table}. Sometimes the @@code{_bfd_link_add_symbols} function must store some information in the hash table entry to be used by the @@code{_bfd_final_link} function. In such a case the output bfd xvec must be checked to make sure that the hash table was created by an object file of the same format. The @@code{_bfd_final_link} routine must be prepared to handle a hash entry without any extra information added by the @@code{_bfd_link_add_symbols} function. A hash entry without extra information will also occur when the linker script directs the linker to create a symbol. Note that, regardless of how a hash table entry is added, all the fields will be initialized to some sort of null value by the hash table entry initialization function. See @@code{ecoff_link_add_externals} for an example of how to check the output bfd before saving information (in this case, the ECOFF external symbol debugging information) in a hash table entry. @@node Adding symbols from an object file, Adding symbols from an archive, Differing file formats, Adding Symbols to the Hash Table @@subsubsection Adding symbols from an object file When the @@code{_bfd_link_add_symbols} routine is passed an object file, it must add all externally visible symbols in that object file to the hash table. The actual work of adding the symbol to the hash table is normally handled by the function @@code{_bfd_generic_link_add_one_symbol}. The @@code{_bfd_link_add_symbols} routine is responsible for reading all the symbols from the object file and passing the correct information to @@code{_bfd_generic_link_add_one_symbol}. The @@code{_bfd_link_add_symbols} routine should not use @@code{bfd_canonicalize_symtab} to read the symbols. The point of providing this routine is to avoid the overhead of converting the symbols into generic @@code{asymbol} structures. @@findex _bfd_generic_link_add_one_symbol @@code{_bfd_generic_link_add_one_symbol} handles the details of combining common symbols, warning about multiple definitions, and so forth. It takes arguments which describe the symbol to add, notably symbol flags, a section, and an offset. The symbol flags include such things as @@code{BSF_WEAK} or @@code{BSF_INDIRECT}. The section is a section in the object file, or something like @@code{bfd_und_section_ptr} for an undefined symbol or @@code{bfd_com_section_ptr} for a common symbol. If the @@code{_bfd_final_link} routine is also going to need to read the symbol information, the @@code{_bfd_link_add_symbols} routine should save it somewhere attached to the object file BFD. However, the information should only be saved if the @@code{keep_memory} field of the @@code{info} argument is TRUE, so that the @@code{-no-keep-memory} linker switch is effective. The a.out function which adds symbols from an object file is @@code{aout_link_add_object_symbols}, and most of the interesting work is in @@code{aout_link_add_symbols}. The latter saves pointers to the hash tables entries created by @@code{_bfd_generic_link_add_one_symbol} indexed by symbol number, so that the @@code{_bfd_final_link} routine does not have to call the hash table lookup routine to locate the entry. @@node Adding symbols from an archive, , Adding symbols from an object file, Adding Symbols to the Hash Table @@subsubsection Adding symbols from an archive When the @@code{_bfd_link_add_symbols} routine is passed an archive, it must look through the symbols defined by the archive and decide which elements of the archive should be included in the link. For each such element it must call the @@code{add_archive_element} linker callback, and it must add the symbols from the object file to the linker hash table. @@findex _bfd_generic_link_add_archive_symbols In most cases the work of looking through the symbols in the archive should be done by the @@code{_bfd_generic_link_add_archive_symbols} function. This function builds a hash table from the archive symbol table and looks through the list of undefined symbols to see which elements should be included. @@code{_bfd_generic_link_add_archive_symbols} is passed a function to call to make the final decision about adding an archive element to the link and to do the actual work of adding the symbols to the linker hash table. The function passed to @@code{_bfd_generic_link_add_archive_symbols} must read the symbols of the archive element and decide whether the archive element should be included in the link. If the element is to be included, the @@code{add_archive_element} linker callback routine must be called with the element as an argument, and the elements symbols must be added to the linker hash table just as though the element had itself been passed to the @@code{_bfd_link_add_symbols} function. When the a.out @@code{_bfd_link_add_symbols} function receives an archive, it calls @@code{_bfd_generic_link_add_archive_symbols} passing @@code{aout_link_check_archive_element} as the function argument. @@code{aout_link_check_archive_element} calls @@code{aout_link_check_ar_symbols}. If the latter decides to add the element (an element is only added if it provides a real, non-common, definition for a previously undefined or common symbol) it calls the @@code{add_archive_element} callback and then @@code{aout_link_check_archive_element} calls @@code{aout_link_add_symbols} to actually add the symbols to the linker hash table. The ECOFF back end is unusual in that it does not normally call @@code{_bfd_generic_link_add_archive_symbols}, because ECOFF archives already contain a hash table of symbols. The ECOFF back end searches the archive itself to avoid the overhead of creating a new hash table. @@node Performing the Final Link, , Adding Symbols to the Hash Table, Linker Functions @@subsection Performing the final link @@cindex _bfd_link_final_link in target vector @@cindex target vector (_bfd_final_link) When all the input files have been processed, the linker calls the @@code{_bfd_final_link} entry point of the output BFD. This routine is responsible for producing the final output file, which has several aspects. It must relocate the contents of the input sections and copy the data into the output sections. It must build an output symbol table including any local symbols from the input files and the global symbols from the hash table. When producing relocatable output, it must modify the input relocs and write them into the output file. There may also be object format dependent work to be done. The linker will also call the @@code{write_object_contents} entry point when the BFD is closed. The two entry points must work together in order to produce the correct output file. The details of how this works are inevitably dependent upon the specific object file format. The a.out @@code{_bfd_final_link} routine is @@code{NAME(aout,final_link)}. @@menu * Information provided by the linker:: * Relocating the section contents:: * Writing the symbol table:: @@end menu @@node Information provided by the linker, Relocating the section contents, Performing the Final Link, Performing the Final Link @@subsubsection Information provided by the linker Before the linker calls the @@code{_bfd_final_link} entry point, it sets up some data structures for the function to use. The @@code{input_bfds} field of the @@code{bfd_link_info} structure will point to a list of all the input files included in the link. These files are linked through the @@code{link_next} field of the @@code{bfd} structure. Each section in the output file will have a list of @@code{link_order} structures attached to the @@code{map_head.link_order} field (the @@code{link_order} structure is defined in @@code{bfdlink.h}). These structures describe how to create the contents of the output section in terms of the contents of various input sections, fill constants, and, eventually, other types of information. They also describe relocs that must be created by the BFD backend, but do not correspond to any input file; this is used to support -Ur, which builds constructors while generating a relocatable object file. @@node Relocating the section contents, Writing the symbol table, Information provided by the linker, Performing the Final Link @@subsubsection Relocating the section contents The @@code{_bfd_final_link} function should look through the @@code{link_order} structures attached to each section of the output file. Each @@code{link_order} structure should either be handled specially, or it should be passed to the function @@code{_bfd_default_link_order} which will do the right thing (@@code{_bfd_default_link_order} is defined in @@code{linker.c}). For efficiency, a @@code{link_order} of type @@code{bfd_indirect_link_order} whose associated section belongs to a BFD of the same format as the output BFD must be handled specially. This type of @@code{link_order} describes part of an output section in terms of a section belonging to one of the input files. The @@code{_bfd_final_link} function should read the contents of the section and any associated relocs, apply the relocs to the section contents, and write out the modified section contents. If performing a relocatable link, the relocs themselves must also be modified and written out. @@findex _bfd_relocate_contents @@findex _bfd_final_link_relocate The functions @@code{_bfd_relocate_contents} and @@code{_bfd_final_link_relocate} provide some general support for performing the actual relocations, notably overflow checking. Their arguments include information about the symbol the relocation is against and a @@code{reloc_howto_type} argument which describes the relocation to perform. These functions are defined in @@code{reloc.c}. The a.out function which handles reading, relocating, and writing section contents is @@code{aout_link_input_section}. The actual relocation is done in @@code{aout_link_input_section_std} and @@code{aout_link_input_section_ext}. @@node Writing the symbol table, , Relocating the section contents, Performing the Final Link @@subsubsection Writing the symbol table The @@code{_bfd_final_link} function must gather all the symbols in the input files and write them out. It must also write out all the symbols in the global hash table. This must be controlled by the @@code{strip} and @@code{discard} fields of the @@code{bfd_link_info} structure. The local symbols of the input files will not have been entered into the linker hash table. The @@code{_bfd_final_link} routine must consider each input file and include the symbols in the output file. It may be convenient to do this when looking through the @@code{link_order} structures, or it may be done by stepping through the @@code{input_bfds} list. The @@code{_bfd_final_link} routine must also traverse the global hash table to gather all the externally visible symbols. It is possible that most of the externally visible symbols may be written out when considering the symbols of each input file, but it is still necessary to traverse the hash table since the linker script may have defined some symbols that are not in any of the input files. The @@code{strip} field of the @@code{bfd_link_info} structure controls which symbols are written out. The possible values are listed in @@code{bfdlink.h}. If the value is @@code{strip_some}, then the @@code{keep_hash} field of the @@code{bfd_link_info} structure is a hash table of symbols to keep; each symbol should be looked up in this hash table, and only symbols which are present should be included in the output file. If the @@code{strip} field of the @@code{bfd_link_info} structure permits local symbols to be written out, the @@code{discard} field is used to further controls which local symbols are included in the output file. If the value is @@code{discard_l}, then all local symbols which begin with a certain prefix are discarded; this is controlled by the @@code{bfd_is_local_label_name} entry point. The a.out backend handles symbols by calling @@code{aout_link_write_symbols} on each input BFD and then traversing the global hash table with the function @@code{aout_link_write_other_symbol}. It builds a string table while writing out the symbols, which is written to the output file at the end of @@code{NAME(aout,final_link)}. @@findex bfd_link_split_section @@subsubsection @@code{bfd_link_split_section} @@strong{Synopsis} @@example bfd_boolean bfd_link_split_section (bfd *abfd, asection *sec); @@end example @@strong{Description}@@* Return nonzero if @@var{sec} should be split during a reloceatable or final link. @@example #define bfd_link_split_section(abfd, sec) \ BFD_SEND (abfd, _bfd_link_split_section, (abfd, sec)) @@end example @@findex bfd_section_already_linked @@subsubsection @@code{bfd_section_already_linked} @@strong{Synopsis} @@example void bfd_section_already_linked (bfd *abfd, asection *sec, struct bfd_link_info *info); @@end example @@strong{Description}@@* Check if @@var{sec} has been already linked during a reloceatable or final link. @@example #define bfd_section_already_linked(abfd, sec, info) \ BFD_SEND (abfd, _section_already_linked, (abfd, sec, info)) @@end example @ 1.1.1.1 log @Import binutils 2.19.1 as requested by matt@@ OK'ed by board@@ @ text @@ 1.1.1.2 log @from ftp.gnu.org @ text @d179 1 a179 4 symbols from the object file to the linker hash table.

This compiler, the gcc provided by Oracle and also gcc bootstrapped from sources on that platform with a default configuration will by default generate 32-bit binaries -- even on a 64-bit platform. And __amd64 will not be defined for compilations targeting a 32-bit platform. This is different from the corresponding behaviour on GNU/Linux systems where the local platform is targeted by default. Thus, as long as you do not add "-m64" or if you have a custom-built gcc which defaults to 64 bit, you will get 32-bit binaries on Solaris despite living on a 64-bit platform. * config.guess (i86pc:SunOS:5.*:* || i86xen:SunOS:5.*:*): Adapt the test by adding the "-m64" flag.

For example: % dash -c 'x=good; x=bad echo >/dev/null; echo $x' good % jsh -c 'x=good; x=bad echo >/dev/null; echo $x' bad The config.sub script contains a few commands of the form: IFS=- read ... which triggers this bug, causing the IFS assignment to persist for the remainder of the script. This can cause misbehaviour in certain cases, for example: % jsh config.sub i386-linux-gnu config.sub: test: unknown operator gnu % jsh config.sub i386-gnu/linux sed: can't read s|gnu/linux|gnu|: No such file or directory Invalid configuration `i386-gnu/linux': OS `' not recognized * config.sub: Save and restore IFS explicitly to avoid shell bugs. * doc/config.sub.1: Regenerate. 2021-08-04 Jeremy Soller config.sub: add Linux Relibc Target $ make check cd testsuite && bash config-guess.sh && rm uname PASS: config.guess checks (136 tests) cd testsuite && bash config-sub.sh PASS: config.sub checks (881 tests) PASS: config.sub idempotency checks (818 tests) PASS: config.sub canonicalise each config.guess testcase (136 tests) * config.sub (relibc*): Recognize. * doc/config.sub.1: Regenerate. * testsuite/config-sub.data (x86_64-linux-relibc): New test. 2021-07-06 Stephanos Ioannidis config.sub: add Zephyr RTOS support This adds the Zephyr RTOS targets in preparation for implementing the Zephyr RTOS-specific toolchain support. $ make check cd testsuite && bash config-guess.sh && rm uname PASS: config.guess checks (136 tests) cd testsuite && bash config-sub.sh PASS: config.sub checks (880 tests) PASS: config.sub idempotency checks (817 tests) PASS: config.sub canonicalise each config.guess testcase (136 tests) * config.sub (zephyr*): Recognize. * doc/config.sub.1: Regenerate. * testsuite/config-sub.data: Add testcases for *-zephyr. 2021-07-03 Ozkan Sezer config.sub: disable shellcheck SC2006 / SC2268 warnings This is in line with the recent config.guess change in commit 12fcf67c9108f4c4b581eaa302088782f0ee40ea * config.sub (shellcheck disable): Add SC2006,SC2268.

This patch was generated using the included GNU Awk program. * config.guess: Revert POSIX command substitutions to classic form. * patch-6.gawk: Store the tool that produced the automated patch. 2021-05-26 Jacob Bachmeyer config.guess: manual fixup after previous automated patches This patch provides the special handling for the GNU system. As these were two small and unique edits, they were not included in the scripts. This patch also cleans up other minor issues that must be addressed before reverting to classic command substitutions and updates "shellcheck" directives to account for changes in this script and the change in "shellcheck" towards reporting individual portability issues. 2021-05-26 Jacob Bachmeyer config.guess: automatic fixups after previous automated patch This patch was generated using the following command: sed -i config.guess \ -e '/="[^"]\+"\(-\|$\)/s/="\([^"([:space:])]\+\)"/=\1/' \ -e '/="[^"]\+"[[:alnum:]]/s/="\$\([^([:space:])]\+\)"/=${\1}/' \ -e \ '/\$(echo[^|]\+|/s/\([^[:space:]]\)[[:space:]]*|[[:space:]]*sed/\1 | sed/g' * config.guess: Remove unneeded quotes in other variable assignments, standardize spacing for "echo ... | sed" substitutions. 2021-05-26 Jacob Bachmeyer config.guess: remove unneeded quotes and factor command substitutions This is further cleanup and simplifies some constructs that can confuse Emacs' syntax highlighting while generally reducing required quoting.

The assembler now supports .errif and .warnif directives, permitting user-controlled diagnostics with conditionals that are evaluated only at the end of assembly. The assembler predefines the symbol "GAS(version)". The assembler now supports the generation of SFrame stack trace information (.sframe) from CFI directives on s390 64-bit (s390x). For RISC-V, the ".option arch, -ext" format is deprecated due to its controversial use. For RISC-V, stop generating mapping symbols $x and replace with $x. The $x was defined to have the same ISA as previous $x, but now is defined to have the same ISA as elf architecture attribute. Once both used .option arch/rvc/norvc/push/pop directives (some code have different architectures with file attribute) and data directives in text, then the file need to be rebuilt since 2.45. The assembler supports the latest architecture extensions for the RISC-V, LoongArch and AArch64 architectures. Linker: The linker's --stats option can take an optional argument which if used is interpreted as a filename into which resource usage information should be stored. As an alternative mechanism the LD_STATS environment variable can also be used to achieve the same results. Resource usage information for various phases of the linking operation is now included in the report. If a map file is being produced then the information is also included there. The --no-stats option can be used to disable stat reporting, should it have been enabled. On s390 64-bit (s390x), generate SFrame stack trace information (.sframe) for the linker generated .plt section. On s390 32-bit, generate ".eh_frame" unwind information for the linker generated .plt section. Both features are enabled by default and can be disabled using linker option --no-ld-generated-unwind-info. On RISC-V, add new PLT formats, and GNU property merge rules for zicfiss and zicfilp extensions. On AVR, the default linker scripts now assert that the .progmem sections don't extend past 0xffff since they are accessed by means of LPM. For data in program memory that may be located past 0xffff, a .progmemx section should be used. On LoongArch, linker relaxation time complexity is no longer quadratic with respect to relocation counts. Linking time of large software should be improved. In addition R_LARCH_32_PCREL records are now checked for overflow. Other binary utilities: New versioned release of libsframe: libsframe.so.2. This release introduces versioned symbols with version node name LIBSFRAME_2.0. Some new symbols have been added to support the new flag SFRAME_F_FDE_FUNC_START_PCREL and retrieving flags from SFrame decoder and encoder objects: - Addition of sframe_decoder_get_flags, sframe_decoder_get_offsetof_fde_start_addr, sframe_encoder_get_flags, sframe_encoder_get_offsetof_fde_start_addr. This release also includes backward-incompatible ABI changes: - Removal of sframe_get_funcdesc_with_addr. - Change in the behavior of sframe_decoder_get_funcdesc_v2, sframe_encoder_add_funcdesc_v2 and sframe_encoder_write. For SFrame stack trace format, the function start address in each SFrame FDE has a changed encoding: The 32-bit signed integer now holds the offset of the start PC of the associated function from the sfde_func_start_address field itself (instead of the earlier where it was the offset from the start of the SFrame section itself). All SFrame sections generated by gas and ld now default to this new encoding, setting the (new) SFRAME_F_FDE_FUNC_START_PCREL flag. Relocatable SFrame links are now fixed. Readelf now recognizes RISC-V GNU_PROPERTY_RISCV_FEATURE_1_CFI_SS and GNU_PROPERTY_RISCV_FEATURE_1_CFI_LP_UNLABELED for zicfiss and zicfilp extensions. The LoongArch disassembler now properly accepts multiple disassembly options given by -M, such as "-M no-aliases,numeric". (Previously only the first option took effect.) 2.44 Release Notes ------------------ Assembler: Support for new architecture extensions for AArch64, Risc-V and x86. Linker: The default maximum page size was changed from 16KiB to 64KiB for LoongArch. This now supports mixed LTO and non-LTO object files in relocatable output. The ELF forms of the linker support a --image-base= option for compatibility with LLD. The --build-id= option now accepts an argument of "xx" which enables the use of the xxhash library. This produces a 128-bit hash and is 2-4x faster than md5 or sha1. The ELF linker option --package-metadata supports percent-encoded and %[string] encoded JSON payloads. Disassembler: The RISC-V disassembler now supports -M,max option like QEMU to dump instruction without checking architecture support as usual. GprofNG: Support added for hardware event counters for Neoverse-N1, Ampere-1, and Appliedmicro processors. Support for the Nios II target has been removed. 2.43 Release Notes ------------------ Assembler: * Add a .base64 directive to the assembler which allows base64 encoded binary data to be provided as strings. * Assembler macros as well as the bodies of .irp / .irpc / .rept can now use the syntax \+ to access the number of times a given macro has been executed. This is similar to the already existing \@@ syntax, except that the count is maintained on a per-macro basis. * References to FB and dollar labels, when supported, are no longer permitted in a radix other than 10. (Note that definitions of such labels were already thus restricted, except that leading zeroes were permitted). Linker: * Add support for DT_RELR type compressed runtime relocations for the AArch64 and LoongArch architectures. * Add --rosegment option which changes the -z separate-code option so that only one read-only segment is created (instead of two). * Add --section-ordering-file option to add extra mapping of input sections to output sections. * Add -plugin-save-temps to store plugin intermediate files permanently. Utilities: * Readelf will now display DT_RELR relocations in full detail. * Readelf now has a -j/--display-section option which takes the name or index of a section and displays its contents according to its type. The option can be used multiple times on the command line to display multiple sections. * When objdump or readelf are used to display the contents of a .eh_frame section they will now also display the contents of the .eh_frame_hdr section, if present. Gprofng: * Improved the support for hardware event counters: - Re-designed and streamlined the implementation. - Defined a common set of events for ARM processors. - Added specific events for AMD ZEN3 / ZEN4, and Intel Ice Lake processors. * Added a minimal support for RISC-V. General: * Target specific improvements for many architectures. @ text @a346 40 @@findex _bfd_generic_link_add_one_symbol @@subsubsection @@code{_bfd_generic_link_add_one_symbol} @@deftypefn {Function} bool _bfd_generic_link_add_one_symbol (struct bfd_link_info *info, bfd *abfd, const char *name, flagword flags, asection *section, bfd_vma value, const char *string, bool copy, bool collect, struct bfd_link_hash_entry **hashp); Add a symbol to the global hash table.
