x86-64 assembly codes vs C source codes

["H.J. Lu" <hjl.tools@gmail.com>]

Hi,

There are 421 x86-64 assembly source files.  Majority of
them have generic versions in C.  We added many x86-64
assembly source files for performance.   Most of x86-64
assembly source files started from the generic version in C.
They were compiled into assembly and optimized by hand.
Intel is committed to support x86-64 assembly source files
to improve performance and fix any bugs.

For 2.35, we'd like to add more x86-64 assembly source
files to libmvec.   The x86-64 assembly source files are the
preferred form for performance and accuracy today.

We will evaluate the generic alternative in the future
if it has similar performance and accuracy as the
assembly version, like:

ba4b8fab20 x86-64: Remove s_sincosf-sse2.S
4ca945e9c5 x86-64: Remove sysdeps/x86_64/fpu/s_cosf.S
9574c7b68d x86-64: Remove sysdeps/x86_64/fpu/s_sinf.S
e1f59bebd8 x86-64: Replace assembly versions of e_expf with generic e_expf.c
8537e0f6cf x86-64: Implement libmathvec IFUNC selectors in C
10a87ca476 x86-64: Implement libm IFUNC selectors in C
11ffcacb64 x86-64: Implement strcmp family IFUNC selectors in C
70fe2eb794 x86-64: Implement strcspn/strpbrk/strspn IFUNC selectors in C
9f4254b8bd x86-64: Implement wcscpy IFUNC selector in C
9ed0aa15d3 x86-64: Implement strcat family IFUNC selectors in C
b91a52d0d7 x86-64: Implement memcmp family IFUNC selectors in C
93e46f8773 x86-64: Implement memset family IFUNC selectors in C
5c3e322d3b x86-64: Implement memmove family IFUNC selectors in C
5a103908c0 x86-64: Implement strcpy family IFUNC selectors in C

Thanks.
