Subject: [PATCH 04/10] S390: Move utf16-utf32-z9.c to multiarch folder and use
|
||||
s390_libc_ifunc_expr macro.
|
||||
|
||||
upstream-commit 85286aaf1dd7216a64964752d147c5ce3c4067d0
|
||||
|
||||
The utf16-utf32-z9.c iconv module is using ifunc and thus the ifunc part should
|
||||
be in multiarch folder. Otherwise ifunc is used even if you configure
|
||||
with --disable-multi-arch.
|
||||
|
||||
This patch moves the ifunc resolvers to the new file
|
||||
sysdeps/s390/multiarch/utf16-utf32-z9.c. The resolvers are now implemented
|
||||
with s390_libc_ifunc_expr macro instead of using gcc attribute ifunc directly.
|
||||
|
||||
The ifunc versions are implemented in sysdeps/s390/utf16-utf32-z9.c.
|
||||
Each version is only implemented if needed or supported. Therefore there is
|
||||
a block at beginning of the file which selects the versions which should be
|
||||
defined depending on support for multiarch, vector-support and used minimum
|
||||
architecture level. This block defines HAVE_[FROM|TO]_[C|VX] to 1 or 0.
|
||||
The code below is rearranged and surrounded
|
||||
by #if HAVE_[FROM|TO]_[C|VX] == 1. There is no functional change.
|
||||
|
||||
ChangeLog:
|
||||
|
||||
* sysdeps/s390/multiarch/utf16-utf32-z9.c: New File.
|
||||
* sysdeps/s390/utf16-utf32-z9.c: Move ifunc resolvers to multiarch
|
||||
folder and define ifunc versions depending on HAVE_[FROM|TO]_[C|VX].
|
||||
(HAVE_FROM_C, HAVE_FROM_VX, HAVE_TO_C, HAVE_TO_VX, FROM_LOOP_DEFAULT,
|
||||
FROM_LOOP_C, FROM_LOOP_VX, TO_LOOP_DEFAULT, TO_LOOP_C, TO_LOOP_VX):
|
||||
New Define.
