Bug #: 54273
Summary: [4.7] ICE in extract_constrain_insn_cached with
--float=soft, --target=powerpc-unknown-linux-gnu
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: inline-asm
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sim...@google.com
gcc.target/powerpc/regnames-1.c fails in gcc-4_7-branch at r190414 with
--target=powerpc-unknown-linux-gnu --float=soft. I haven't yet checked 4.8.
Repro, using a cross-gcc hosted on x86_64:
configure \
--enable-languages=c \
--build=x86_64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu \
--target=powerpc-unknown-linux-gnu \
--with-float=soft
make -j6 all-gcc
make RUNTESTFLAGS='powerpc.exp=regnames-1.c' check-gcc
