Gražvydas Ignotas fc9d7c7fe3 rename arm32 sgemm_kernel to indicate neon support 2026-05-05 23:09:52 +03:00
Gražvydas Ignotas 9d58b8d64e provide a NEON version of arm/sgemm 
benchmark/sgemm.goto before:
 M= 200, N= 200, K= 200 :     9262.97 MFlops   0.001727 sec
after:
 M= 200, N= 200, K= 200 :    30223.64 MFlops   0.000529 sec

Conveniently the registers are already allocated suitably for vector
operation, so the conversion from vfpv3 was rather straightforward.

Prefetching was left out because it doesn't help Cortex-A76,
only hurts it slightly.

Gražvydas Ignotas cd276c2c09 only save the required registers for arm/sgemm 
According to ARM AAPCS (Procedure Call Standard) 5.1.2.1, only registers
s16-s31 must be preserved across subroutine calls; registers s0-s15
do not need to be preserved.

Gražvydas Ignotas d7aeae8933 convert labels to local labels for arm/sgemm 
Non-local labels interfere with profiling. Same thing was done for arm64 in
commit a0128aa489.

Separate implementations of AMAX and IAMAX on arm

Ashwin Sekhar T K f02d535fde arm: Fix clang compilation for ARMv7 
clang is not recognizing some pre-UAL VFP mnemonics like fnmacs, fnmacd,
fnmuls and fnmuld. Replaced them with equivalent UAL mnemonics which are
vmls.f32, vmls.f64, vnmul.f32 and vnmul.f64 respectively.
