| ==================================================================== | |||
| Version 0.3.24 | |||
| 03-Sep-2023 | |||
| general: | |||
| - declared the arguments of cblas_xerbla as const (in accordance with the reference implementation | |||
| and others, the previous discrepancy appears to have dated back to GotoBLAS) | |||
| - fixed the implementation of ?GEMMT that was added in 0.3.23 | |||
| - made cpu-specific SWITCH_RATIO parameters for GEMM available to DYNAMIC_ARCH builds | |||
| - fixed application of SYMBOLSUFFIX in CMAKE builds | |||
| - fixed missing SSYCONVF function in the shared library | |||
| - fixed parallel build logic used with gmake | |||
| - added support for compilation with LLVM17, in particular its new Fortran compiler | |||
| - added support for CMAKE builds using the NVIDIA HPC compiler | |||
| - fixed INTERFACE64 builds with CMAKE and the f95 Fortran compiler | |||
| - fixed cross-build detection and management in c_check | |||
| - disabled building of the tests with CMAKE when ONLY_CBLAS is defined | |||
| - fixed several issues with the handling of runtime limits on the number of OPENMP threads | |||
| - corrected the error code returned by SGEADD/DGEADD when LDA is too small | |||
| - corrected the error code returned by IMATCOPY when LDB is too small | |||
| - updated ?NRM2 to support negative increment values (as introduced in release 3.10 | |||
| of the reference BLAS) | |||
| - fixed OpenMP builds with CLANG for the case where libomp is not in a standard location | |||
| - fixed a potential overwrite of unrelated memory during thread initialisation on startup | |||
| - fixed a potential integer overflow in the multithreading threshold for ?SYMM/?SYRK | |||
| - fixed build of the LAPACKE interfaces for the LAPACK 3.11.0 ?TRSYL functions added in 0.3.22 | |||
| - fixed installation of .cmake files in concurrent 32 and 64bit builds with CMAKE | |||

| - fixed actual arguments passed to a number of LAPACK functions (from Reference-LAPACK PR 885) | |||
| - fixed workspace query results in LAPACK ?SYTRF/?TRECV3 (from Reference-LAPACK PR 883) | |||
| - fixed derivation of the UPLO parameter in LAPACKE_?larfb (from Reference-LAPACK PR 878) | |||
| - fixed a crash in LAPACK ?GELSDD on NRHS=0 (from Reference-LAPACK PR 876) | |||
| - added new LAPACK utility functions CRSCL and ZRSCL (from Reference-LAPACK PR 839) | |||
| - corrected the order of eigenvalues for 2x2 matrices in ?STEMR (Reference-LAPACK PR 867) | |||
| - removed spurious reference to OpenMP variables outside OpenMP contexts (Reference-LAPACK PR 860) | |||

| - fixed potential stack overflows in the EIG part of the LAPACK testsuite (Reference-LAPACK PR 854) | |||
| - applied small improvements to the variants of Cholesky and QR functions (Reference-LAPACK PR 847) | |||
| - removed unused variables from LAPACK ?BDSQR (Reference-LAPACK PR 832) | |||
| - fixed a potential crash on allocation failure in LAPACKE SGEESX/DGEESX (Reference-LAPACK PR 836) | |||
| - added a quick return from SLARUV/DLARUV for N < 1 (Reference-LAPACK PR 837) | |||
