Kewen, Segher, Peter:
The following patch is a redo of the previous "rs6000: Fix
__builtin_vec_xst_trunc definition" patch.
This patch fixes the argument in the two builtin definitions
__builtin_altivec_tr_stxvrwx and __builtin_altivec_tr_stxvrhx. It also
adds with a testcase to validate the related builtins which have the
third argument of char *, short *, int * and long long *.
I have tested the patch on Power 10 with no regressions.
Please let me know if this patch is acceptable for mainline.
Carl
------------------------------------------------------------
rs6000: Fix arguments for __builtin_altivec_tr_stxvrwx,
__builtin_altivec_tr_stxvrhx
The third argument for __builtin_altivec_tr_stxvrhx should be short *
not int *. Similarly, the third argument for __builtin_altivec_tr_stxvrwx
should be int * not short *. This patch fixes the arguments in the two
builtins.
A runnable test case is added to test the __builtin_altivec_tr_stxvrbx,
__builtin_altivec_tr_stxvrhx, __builtin_altivec_tr_stxvrwx and
__builtin_altivec_tr_stxvrdx builtins.
gcc/
* config/rs6000/rs6000-builtins.def (__builtin_altivec_tr_stxvrhx,
__builtin_altivec_tr_stxvrwx): Fix type of third argument.
gcc/testsuite/
* gcc.target/powerpc/builtin_altivec_tr_stxvr_runnable.c: New test
for __builtin_altivec_tr_stxvrbx, __builtin_altivec_tr_stxvrhx,
__builtin_altivec_tr_stxvrwx, __builtin_altivec_tr_stxvrdx.
