--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Vladimir Makarov <vmaka...@gcc.gnu.org>: https://gcc.gnu.org/g:a89c5d3539c36f160ca5b997324ebcd3d601d56e commit r11-6778-ga89c5d3539c36f160ca5b997324ebcd3d601d56e Author: Vladimir N. Makarov <vmaka...@redhat.com> Date: Mon Jan 18 16:41:39 2021 -0500 [PR97847] IRA: Skip abnormal critical edge splitting PPC64 can generate jumps with clobbered pseudo-regs and a BB with such jump can have abnormal output edges. IRA hits an assert when trying to split abnormal critical edge to deal with asm goto output reloads later. The patch just skips splitting abnormal edges. It is assumed that asm-goto with output reloads can not be in BB with output abnormal edges. gcc/ChangeLog: PR target/97847 * ira.c (ira): Skip abnormal critical edge splitting.
