rs6000, remove __builtin_vsx_vperm_* built-ins
The undocumented built-ins:
__builtin_vsx_vperm_16qi_uns,
__builtin_vsx_vperm_1ti,
__builtin_vsx_vperm_1ti_uns,
__builtin_vsx_vperm_2df,
__builtin_vsx_vperm_2di,
__builtin_vsx_vperm_2di_uns,
__builtin_vsx_vperm_4sf,
__builtin_vsx_vperm_4si,
__builtin_vsx_vperm_4si_uns
are duplicats of the __builtin_altivec_* built-ins that are used by
the overloaded vec_perm built-in that is documented in the PVIPR.
gcc/ChangeLog:
* config/rs6000/rs6000-builtins.def (__builtin_vsx_vperm_16qi_uns,
__builtin_vsx_vperm_1ti, __builtin_vsx_vperm_1ti_uns,
__builtin_vsx_vperm_2df, __builtin_vsx_vperm_2di,
__builtin_vsx_vperm_2di_uns, __builtin_vsx_vperm_4sf,
__builtin_vsx_vperm_4si, __builtin_vsx_vperm_4si_uns): Remove
built-in definitions and comments.
gcc/testsuite/ChangeLog:
* gcc.target/powerpc/vsx-builtin-3.c (__builtin_vsx_vperm_16qi_uns,
__builtin_vsx_vperm_1ti, __builtin_vsx_vperm_1ti_uns,
__builtin_vsx_vperm_2df, __builtin_vsx_vperm_2di,
__builtin_vsx_vperm_2di_uns, __builtin_vsx_vperm_4sf,
__builtin_vsx_vperm_4si, __builtin_vsx_vperm_4si_uns,
__builtin_vsx_vperm): Change call to built-in to the overloaded
built-in vec_perm.
