ColumbusAI 7bf848454d Update zsum.c -- fixed spelling error to successfully compile 
spelling error where zsum_kernel is used and it should be zasum_kernel. Will not compile without fix.

Vaisakh K V 04915be829 Add vector registers to clobber list to prevent compiler optimization. 
SME based SGEMMDIRECT kernel uses the vector registers (z) and adding
    clobber list informs compiler not to optimize these registers.

Egbert Eich ea6515c4b3 On zarch don't produce objects from assembler with a writable stack section 
On z-series, the current version of the GNU toolchain produces warnings
such as:
```
/usr/lib64/gcc/[...]/s390x-suse-linux/bin/ld: warning: ztrmm_kernel_RC_Z14.o: missing .note.GNU-stack section implies
executable stack
/usr/lib64/[...]/s390x-suse-linux/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
```
To prevent this message and make sure we are future proof, add
```
	.section        .note.GNU-stack,"",@progbits
```
Also add the `.size` bit to give the asm defined functions a proper size
in the symbol table.

Ruiyang Wu 02fd1df10b CMake: Pass OpenMP compiler and linker flags through CMake targets 
Using `OpenMP::OpenMP_LANG` targets for CMake is less error-prone than
passing the compiler and linker flags manually. Furthermore, it allows
the user to customize those flags by setting `OpenMP_LANG_FLAGS`,
`OpenMP_LANG_LIB_NAMES`, and `OpenMP_omp_LIBRARY`.

gxw 2c4a5cc6e6 LoongArch64: Fixed snrm2_lsx.S and cnrm2_lsx.S 
When the data type is single-precision real or single-precision complex,
converting it to double precision does not prevent overflow (as exposed in LAPACK tests).
The only solution is to follow C's approach: find the maximum value in the
array and divide each element by that maximum to avoid this issue
