Bug ID: 110183
Summary: ICE in extract_constrain_insn, at recog.cc:2692 on
s390x-linux-gnu
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-gnu
Target: s390x-linux-gnu
With a cross compiler (revision r14-1637-gcd9c7f898d6e63)
configured with:
/home/worker/buildworker/tiber-gcc-trunk-s390x/build/configure
--enable-languages=c,c++,fortran,rust,m2 --disable-bootstrap
--disable-libsanitizer --disable-multilib --enable-checking=release
--prefix=/home/worker/cross --target=s390x-linux-gnu
--with-as=/usr/bin/s390x-suse-linux-as
and our existing testcase gcc/testsuite/gcc.c-torture/compile/pr106101.c,
compiling it as
~/cross/bin/s390x-linux-gnu-gcc
/home/worker/buildworker/tiber-option-juggler/build/gcc/testsuite/gcc.c-torture/compile/pr106101.c
-fno-tree-ccp -O1 -funroll-loops -w
