Bug ID: 90497
Summary: [10 Regression] Broken bootstrap on i686-linux
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
Assuming since the recent MMX in SSE changes, i686-linux doesn't bootstrap
anymore.

This is i386 ../configure --enable-languages=default,obj-c++,lto,go,brig,d
--enable-checking=yes,rtl,extra bootstrap, so no sse/sse2 is enabled by
default.
