Bug ID: 109987
Summary: ICE in in rs6000_emit_le_vsx_store on ppc64le with
-Ofast -mno-power8-vector
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux
Target: ppc64le-linux-gnu
With a cross compiler (revision r14-1248-gd156c605420023)
configured with:
/home/worker/buildworker/tiber-gcc-trunk-ppc64le/build/configure
--enable-languages=c,c++,fortran,rust,m2 --disable-bootstrap
--disable-libsanitizer --disable-multilib --enable-checking=release
--prefix=/home/worker/cross --target=ppc64le-linux-gnu
--with-as=/usr/bin/powerpc64le-suse-linux-as
and our existing testcase gcc/testsuite/gcc.target/powerpc/pr102347.c, running
it as
~/cross/bin/ppc64le-linux-gnu-gcc
/home/worker/buildworker/tiber-option-juggler/build/gcc/testsuite/gcc.target/powerpc/pr102347.c
