general:
- updated the included LAPACK to Reference-LAPACK 3.10.1
- when no Fortran compiler is available, OpenBLAS builds will now automatically
build LAPACK from an f2c-converted copy of LAPACK 3.9.0 unless the NO_LAPACK option
is specified (more recent releases make too heavy use of Fortran90+ features to be easily convertible to C) - similarly added C versions of the BLAS and CBLAS tests
- enabled building of the ReLAPACK GEMMT kernels when ReLAPACK is built
- function LAPACKE_lsame is now annotated with the GCC attribute "const" to aid static analyzers
- added USE_TLS to the list of options reported by the openblas_get_config() function
- added openblas_getaffinity() as a Linux-only convenience function wrapping pthread_getaffinity_np()
- CMAKE builds now support the BUILD_TESTING keyword (to disable the LAPACK testsuite) of Reference-LAPACK
- fixed CMAKE builds of the laswp_ncopy and neg_tcopy kernels
- removed the build system requirements for PERL (while keeping the original perl scripts as backup)
- handle building and running OpenBLAS on systems that report zero available cpu cores
- added SYMBOLPREFIX/SYMBOLSUFFIX handling for LAPACK 3.10.0 functions added in 0.3.20
- fixed linking of the utests on QNX
- Added support for compilation with the Intel ifx compiler
- Added support for compilation with the Fujitsu FCC compiler for Fugaku
- Added support for compilation with the Cray C and Fortran compilers
- reverted OpenMP threadpool behaviour in the exec_blas call to its state before 0.3.11, that is
the threadpool will no longer grow or shrink on demand as the overhead for this is too big at least with
GNU OpenMP. The adaptive behaviour introduced in 0.3.11 can still be requested at runtime by setting
the environment variable OMP_ADAPTIVE - worked around spurious STFSM/CTFSM errors reported by the LAPACK testsuite
x86_64:
- fixed determination of compiler support for AVX512 and removed the 0.3.19
workaround for building SKYLAKEX kernels on Sandybridge hardware - fixed compilation for the SKYLAKEX target with gcc 6
- fixed compilation of the CooperLake SBGEMM kernel with LLVM
- fixed compilation of the SkyLakeX small matrix GEMM kernels with LLVM or ICC
- fixed compilation of some BFLOAT16 kernels with CMAKE
- added support for the Zhaoxin/Centaur KH40000 cpu
- fixed a potential crash in the ZSYMV kernel used for all targets except generic
- fixed gmake compilation for DYNAMIC_ARCH with a DYNAMIC_LIST including ATOM
- fixed compilation of LAPACKE with the INTEGER64 option on Windows
- added support for cross-compiling to individual Intel or AMD targets using CMAKE
(previously only CORE2 supported, added targets are ATOM, PRESCOTT, NEHALEM, SANDYBRIDGE,
HASWELL,SKYLAKEX, COOPERLAKE, SAPPHIRERAPIDS, OPTERON, BARCELONA, BULLDOZER, PILEDRIVER,
STEAMROLLER,EXCAVATOR, ZEN)
SPARC:
- worked around an overflow error in the DNRM2 kernel
POWER:
- worked around an overflow error in the POWER6 DNRM2 kernel
- fixed compilation on PPC440
- fixed a performance regression in the level1 BLAS on POWER10
- fixed the POWER10 ZGEMM kernel
- fixed singlethreaded builds for POWER10
- fixed compilation of the POWER10 DGEMV kernel with older gcc versions
- enabled compilation of the BFLOAT16 kernels by default
- enabled the small matrix kernels by default for DYNAMIC_ARCH builds
- added a workaround for a miscompilation of the CDOT and ZDOT kernels by GCC 12
RISCV:
- fixed cpu autodetection logic
ARMV8:
- added an SBGEMM kernel for Neoverse N2
- worked around an overflow error in the DNRM2 kernel used on M1, NeoverseN1, ThunderX2T99
- added support for ARM64 systems running MS Windows
- added support for cross-compiling to the GENERIC ARMV8 target under CMAKE (Windows/MSVC)
- fixed a performance regression in the generic ARMV8 DGEMM kernel introduced in 0.3.19
- added initial support for the Apple M1 cpu under Linux
- added initial support for the Phytium FT2000 cpu
- added initial support for the Cortex A510, A710, X1 and X2 cpu
- fixed an accidental mixup of cpu identifiers in the autodetection code introduced in 0.3.20
- fixed linking of Apple M1 builds on macOS 12 and later with recent XCode
- made NeoverseN2 available in DYNAMIC_ARCH builds
MIPS,MIPS64:
- worked around an overflow error in the DNRM2 kernel
LOONGARCH64:
- worked around an overflow error in the DNRM2 kernel
- added preliminary support for the LOONGSON2K1000 cpu
- added DYNAMIC_ARCH support
