--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Aldy Hernandez <al...@gcc.gnu.org>: https://gcc.gnu.org/g:2364b584552208ce715fa4fd44c510b7e5210d1e commit r12-1118-g2364b584552208ce715fa4fd44c510b7e5210d1e Author: Aldy Hernandez <al...@redhat.com> Date: Fri May 28 22:17:51 2021 +0200 Fix i686 bootstrap by temporarily disabling exporting of global ranges. The patch converting evrp to the get_range_query(fun) API broke i686 bootstrap (commit 57bf37515). The problem seems to be in a subsequent pass that has more up-to-date global ranges. I won't be able to look at this until next week, so I am reverting the problematic bit of the patch-- the exporting of global ranges once evrp finishes. The use of the new API remains. Reverting the behavior shouldn't be a problem as we never used to export global ranges from ranger. This was new behavior in the patchset. Tested on x86-64 Linux with a bootstrap and regtest, and on x86-32 with only a bootstrap and the configure flags from the PR: --enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --with-fpmath=sse --enable-languages=c,c++ --enable-cet i686-linux --enable-bootstrap --with-fpmath=sse --disable-libcc1 --disable-libcilkrts --disable-libsanitizer gcc/ChangeLog: PR tree-optimization/100787 * gimple-ssa-evrp.c: Disable exporting of global ranges. gcc/testsuite/ChangeLog: * gcc.dg/Wstringop-overflow-55.c: * gcc.dg/pr80776-1.c:
