Version 0.3.27
 4-Apr-2024

general:
- added initial (generic) support for the CSKY architecture
- capped the maximum number of threads used in GEMM, GETRF and POTRF to avoid creating
  underutilized or idle threads
- sped up multithreaded POTRF on all platforms
- added extension openblas_set_num_threads_local() that returns the previous thread count
- re-evaluated the SGEMV and DGEMV load thresholds to avoid activating multithreading
  for too small workloads
- improved the fallback code used when the precompiled number of threads is exceeded,
  and made it callable multiple times during the lifetime of an instance
- added CBLAS interfaces for the BLAS extensions ?AMIN,?AMAX, CAXPYC and ZAXPYC
- fixed a potential buffer overflow in the interface to the GEMMT kernels
- fixed use of incompatible pointer types in GEMMT and C/ZAXPBY as flagged by GCC-14
- fixed unwanted case sensitivity of the character parameters in ?TRTRS

- fixed sizing of logical variables in INTERFACE64 builds of the C version of LAPACK
- fixed inclusion of new LAPACK and LAPACKE functions from LAPACK 3.11 in the shared library
- added a testsuite for the BLAS extensions
- modified the error thresholds for SGS/DGS functions in the LAPACK testsuite to suppress
  spurious errors
- added support for building the benchmark collection with CMAKE
- added rewriting of linker options to avoid linking both libgomp and libomp in CMAKE builds
  with OpenMP enabled that use clang with gfortran
- fixed building on systems with ucLibc
- added support for calling ?NRM2 with a negative increment value on all architectures
- added support for the LLVM18 version of the flang-new compiler
- fixed handling of the OPENBLAS_LOOPS variable in several benchmarks

Reform library linking commands to work for any library naming setup, ensuring
that we got the generic libopenblas.so.0 and libopenblas.so names, either as
symlink or as library file.

Remove duplicate definition of SUFFIX64.

Simplify and fix the pkg-config file for FIXED_LIBNAME.

@math/openblas*: more portable sed for .pc modification

The old path added \b, which is not POSIX BRE. [:space:] works better with
differing seds. It removes more than \b, but in our installs, the following
suffix variable is emtpy, anyway.

@math/openblas: Fix pkg-config file for current version.

The last update broke the library name in the installed pkg-config file
for the openblas variants. Fixing this.

Our type of library naming should be pushed upstream, or adapted to
some other scheme.

	* Fixed several bugs in the LAPACK testsuite

	* Improve thread reinitialization performance with OpenMP after a fork

	  for a particular precision by specifying BUILD_SINGLE, BUILD_DOUBLE

	  reflected in the generated cblas.h

@openblas: update to 0.3.10, fixing build with gcc 10

Fix openblas build issues, mainly by updating to 0.3.10.

This pulls in these commits from WIP (newest first):

commit 3c6284cba90280bc367cf4d1d8252ae4d6e92e76
Author: Jason Bacon <bacon@@NetBSD.org>
Date:   Thu Feb 25 11:56:13 2021 -0600

    openblas: Update ONLY_FOR_PLATFORMS documentation

commit 8071bf28f3ffc95af046ff3eaaac6983f4f70035
Author: Jason Bacon <bacon@@NetBSD.org>
Date:   Thu Feb 25 11:51:32 2021 -0600

    openblas*: Successful build on NetBSD

commit 056e3d5c972a4b286e8755dbee323a9951855165
Author: Dr. Thomas Orgis <thomas.orgis@@uni-hamburg.de>
Date:   Wed Feb 24 18:40:17 2021 +0100

    openblas: flags from environment again to un-break PICy build

    The bug that prompted us to force the compiler flags in the
    make arguments is fixed. Now we got a different one: The logic
    that decides to add -fPIC where needed is overridden when doing
    this, resulting in relocation errors (strangely, not with every
    toolchain).

    So let's remove that again and take FFLAGS and friends from the
    environment again.

commit 86af17db8526e629c2c02c6af1f1ce7db6f6ba6d
Author: Dr. Thomas Orgis <thomas.orgis@@uni-hamburg.de>
Date:   Thu Nov 12 12:44:39 2020 +0100

    openblas: version 0.3.10

    This updated fixes the build with gcc 10 (segfault in cblat1 test).

    I did not go all the way to the current 0.3.12, as that would
    need some hacking of chosen compiler flags. 0.3.13 should be
    the next one.

    This commit also fixes the ARCH → ARCH_ sed to change all
    occurences on a line.

This fulfills pkg/55999 and was approved by wiz during freeze.
