Bug ID: 110436
Summary: ICE in vectorizable_live_operation, at
tree-vect-loop.cc:10170
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux
Target: aarch64-suse-linux
Using a cross compiler (revision r14-2079-g9326a49c9e9d63) configured with
/home/worker/buildworker/tiber-gcc-trunk-aarch64/build/configure
--enable-languages=c,c++,fortran,rust,m2 --disable-bootstrap
--disable-libsanitizer --disable-multilib --enable-checking=release
--prefix=/home/worker/cross --target=aarch64-linux-gnu
--with-as=/usr/bin/aarch64-suse-linux-as
to compile our own testcase testsuite/gcc.dg/pr83089.c with -O3 results in an
ICE:
