commit 914a4e05572e108201d71dcd3e47da8aeeecd70d

|
||||
S390: Refactor strcpy ifunc handling.
|
||||
|
||||
The ifunc handling for strcpy is adjusted in order to omit ifunc
|
||||
variants if those will never be used as the minimum architecture level
|
||||
already supports newer CPUs by default.
|
||||
Glibc internal calls will then also use the "newer" ifunc variant.
|
||||
|
||||
Note: The fallback s390-32/s390-64 ifunc variants with mvst instruction
|
||||
are now moved to the unified strcpy-z900.S file which can be used for
|
||||
31/64bit. The s390-32/s390-64 files multiarch/strcpy.c and strcpy.S
|
||||
are deleted.
|
||||
|
||||
ChangeLog:
|
||||
|
||||
* sysdeps/s390/multiarch/Makefile
|
||||
(sysdep_routines): Remove strcpy variants.
|
||||
* sysdeps/s390/Makefile (sysdep_routines): Add strcpy variants.
|
||||
* sysdeps/s390/multiarch/ifunc-impl-list.c
|
||||
(__libc_ifunc_impl_list): Refactor ifunc handling for strcpy.
|
||||
* sysdeps/s390/multiarch/strcpy-vx.S: Move to ...
|
||||
* sysdeps/s390/strcpy-vx.S: ... here and adjust ifunc handling.
|
||||
* sysdeps/s390/multiarch/strcpy.c: Move to ...
|
||||
* sysdeps/s390/strcpy.c: ... here and adjust ifunc handling.
|
||||
* sysdeps/s390/ifunc-strcpy.h: New file.
|
||||
* sysdeps/s390/s390-64/strcpy.S: Move to ...
|
||||
* sysdeps/s390/strcpy-z900.S: ... here and adjust to be usable
|
||||
for 31/64bit and ifunc handling.
|
||||
* sysdeps/s390/s390-32/multiarch/strcpy.c: Delete file.
|
||||
* sysdeps/s390/s390-64/multiarch/strcpy.c: Likewise.
|
||||
* sysdeps/s390/s390-32/strcpy.S: Likewise.
