Commit Message
rs6000, remove duplicated built-ins of vecmergl and vec_mergeh
The following undocumented built-ins are same as existing documented
overloaded builtins.
const vf __builtin_vsx_xxmrghw (vf, vf);
same as vf __builtin_vec_mergeh (vf, vf); (overloaded vec_mergeh)
const vsi __builtin_vsx_xxmrghw_4si (vsi, vsi);
same as vsi __builtin_vec_mergeh (vsi, vsi); (overloaded vec_mergeh)
const vf __builtin_vsx_xxmrglw (vf, vf);
same as vf __builtin_vec_mergel (vf, vf); (overloaded vec_mergel)
const vsi __builtin_vsx_xxmrglw_4si (vsi, vsi);
same as vsi __builtin_vec_mergel (vsi, vsi); (overloaded vec_mergel)
This patch removes the duplicate built-in definitions so only the
documented built-ins will be available for use. The case statements in
rs6000_gimple_fold_builtin are removed as they are no longer needed. The
patch removes the now unused define_expands for vsx_xxmrghw_<mode> and
vsx_xxmrglw_<mode>.
gcc/ChangeLog:
* config/rs6000/rs6000-builtins.def (__builtin_vsx_xxmrghw,
__builtin_vsx_xxmrghw_4si, __builtin_vsx_xxmrglw,
__builtin_vsx_xxmrglw_4si, __builtin_vsx_xxsel_16qi): Remove
built-in definition.
* config/rs6000/rs6000-builtin.cc (rs6000_gimple_fold_builtin):
remove case entries RS6000_BIF_XXMRGLW_4SI,
RS6000_BIF_XXMRGLW_4SF, RS6000_BIF_XXMRGHW_4SI,
RS6000_BIF_XXMRGHW_4SF.
* config/rs6000/vsx.md (vsx_xxmrghw_<mode>, vsx_xxmrglw_<mode>):
Remove unused define_expands.
