--- Comment #17 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Will Schmidt <wills...@gcc.gnu.org>: https://gcc.gnu.org/g:eba1113dbdf4b1d0d88755b2538327a1d09837b3 commit r8-10362-geba1113dbdf4b1d0d88755b2538327a1d09837b3 Author: Will Schmidt <will_schm...@vnet.ibm.com> Date: Mon Jul 13 13:38:17 2020 -0500 [PATCH] rs6000 improve handling of built-in initialization [PR95952] Handle a scenario with a combination of old hardware, gcc-8 and binutils where gcc will ICE during it's selftest. This ICE was exposed when the builtin processing for better #pragma support was added, where we no longer skip builtin initialization based on the current mask. Per the bug report and assorted debug, the ICE occurrs when building the gcc-8 branch on a 970* based system with an old binutils. (gcc-9 and newer is OK. binutils 2.34 is reported to allow success). The attached patch adds a clause to the builtin initialization to skip initialization of a builtin when the builtin mask is set but the icode value is zero. The subsequent assert check remains in place. 2020-07-13 Will Schmidt <will_schm...@vnet.ibm.com> gcc/ChangeLog: PR target/95952 * config/rs6000/rs6000.c (altivec_init_builtins): Add continue clause to predicate builtin handling.
