gxw 365936ae1b MIPS64: Using the macro MTC rather than MTC1 2022-09-13 16:39:40 +08:00
Jiaxun Yang a50b29c540 Provide a fallback MIPS64_GENERIC target 
It is really dangerous to fallback to Loongson core on other
MIPS64 processors.

gxw 8d07cf9b67 Fix compilation problem on loongson platform 
Using "make TARGET=GENERIC" on loongson platform will get the following
error messages:
"make[1]: *** No rule to make target 'sgemm_incopy.o', needed by 'libs'"
Add kernel/mips64/KERNEL.generic to slove the problem.

Add proper defaults for IxMIN/IxMAX kernels 
the fallbacks from Makefile.L1 assume a combined source for absolute value and non-absolute (with ifdef USE_ABS) but here we have separate implementations

as trivial copy of ?asum with the fabs replaced by mov to preserve code structure

Revert DOT kernel changes from #1834 
as the failures seen on Loongson3A appear to be limited to DSDOT/SDSDOT (i.e. my hackish "fix" from #1684)
