Dan Horák 681af71d95 drop gcc 15 workaround 
As the assembler routines has correctly specified parameter we can drop
the previously applied workaround in https://github.com/OpenMathLib/OpenBLAS/pull/5409.

Chip Kerchner 3a1417671a POWER: Fixing endianness issue in cswap/zswap kernel for AIX 2024-05-15 19:36:46 -05:00
Amrita H S 87b3d9054f Fix regression SAXPY when compiler with OpenXL compiler. 
SAXPY built with OpenXL regresses when compared to SAXPY
built with gcc. OpenXL compiler doesn't know that the
SAXPY inner kernel assembly is a 64 element loop and
to it the remainder loop is the main loop. It vectorizes
and interleaves the remainder to be a 48 elements per
iteration loop. With a max of 63 iterations, a 48 element
loop is mostly not going to get executed, so the 1 element
scalar loop that is the remainder after that is probably
mostly what gets executed.

This can be fixed by adding a pragma, loop interleave_count(2)
which will result in 8 element loop.
