From 2202299c2aa69385ca5e7574914dabc84fb6a40a Mon Sep 17 00:00:00 2001 From: Kelvin Nilsen Date: Mon, 11 May 2020 16:16:15 -0500 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 * 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.
