Subject: [PATCH] rs6000: Add pdepd and pextd
Add scalar instructions for parallel bit deposit and extract, with
built-in function support.
[gcc]
2020-05-11 Kelvin Nilsen <kelvin@gcc.gnu.org>
* config/rs6000/rs6000-builtin.def (__builtin_pdepd): New built-in
function.
(__builtin_pextd): Likewise.
* config/rs6000/rs6000.md (UNSPEC_PDEPD): New constant.
(UNSPEC_PEXTD): Likewise.
(pdepd): New insn.
(pextd): Likewise.
* doc/extend.texi (Basic PowerPC Built-in Functions Available for
a Future Architecture): Add descriptions of __builtin_pdepd and
__builtin_pextd functions.
[gcc/testsuite]
