Clear odata for aes(enc|dec)(wide)?kl intrinsics when ZF is set.
For Keylocker aesenc/aesdec intrinsics, current implementation
moves idata to odata unconditionally, which causes safety issue when
the instruction meets runtime error. So we add a branch to clear
odata when ZF is set after instruction exectution.
gcc/ChangeLog:
* config/i386/i386-expand.c (ix86_expand_builtin):
Add branch to clear odata when ZF is set for asedecenc_expand
and wideaesdecenc_expand.
gcc/testsuite/ChangeLog:
* gcc.target/i386/keylocker-aesdec128kl.c: Update test.
* gcc.target/i386/keylocker-aesdec256kl.c: Likewise.
* gcc.target/i386/keylocker-aesdecwide128kl.c: Likewise.
* gcc.target/i386/keylocker-aesdecwide256kl.c: Likewise.
* gcc.target/i386/keylocker-aesenc128kl.c: Likewise.
* gcc.target/i386/keylocker-aesenc256kl.c: Likewise.
* gcc.target/i386/keylocker-aesencwide128kl.c: Likewise.
* gcc.target/i386/keylocker-aesencwide256kl.c: Likewise.
