x86-64: Add wcslen optimize for sse4.1
|
|
|
190885 |
|
|
|
190885 |
Added wcsnlen-sse4.1 to the wcslen ifunc implementation list and did
|
|
|
190885 |
not add wcslen-sse4.1 to wcslen ifunc implementation list. This commit
|
|
|
190885 |
fixes that by removing wcsnlen-sse4.1 from the wcslen ifunc
|
|
|
190885 |
implementation list and adding wcslen-sse4.1 to the ifunc
|
|
|
190885 |
implementation list.
|
|
|
190885 |
|
|
|
190885 |
Testing:
|
|
|
190885 |
test-wcslen.c, test-rsi-wcslen.c, and test-rsi-strlen.c are passing as
|
|
|
190885 |
well as all other tests in wcsmbs and string.
