- Reply-to: Jakub Jelinek <jakub at redhat dot com>
Hi!
PR target/21149 fix was committed without a testcase,
here is one adapted for use in gcc.dg.
Fails execution tests with:
make check-gcc RUNTESTFLAGS="--target_board=unix/{-m32,-m64} dg.exp=i386-sse-13.c"
without PR21149 patch and succeeds all tests with that patch.
Ok for HEAD/4.0?
