Bug ID: 66898
Summary: [6 Regression] profiledbootstrap failure on x86
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
CC: ubizjak at gmail dot com
Target Milestone: ---
On Fedora 22/x86-64, r225875 failed to profiledbootstrap when
GCC was configured with
# PATH=/usr/local32/bin:$PATH
# CC="gcc -m32 -fno-lto" CXX="g++ -m32 -fno-lto"
RUNTESTFLAGS="--target_board='unix'"
/export/gnu/import/git/sources/gcc/configure --with-demangler-in-ld
--enable-clocale=gnu --with-system-zlib i686-linux --prefix=/usr/gcc-6.0.0
--enable-gnu-indirect-function --disable-werror --enable-libmpx
--with-fpmath=sse
# make -j8 profiledbootstrap CC="gcc -m32 -fno-lto" CXX="g++ -m32 -fno-lto"
with /usr/local32/bin containing 32-bit binutils. I got
/export/gnu/import/git/sources/gcc/gcc/lto-streamer-out.c: In function ‘void
lto_output_location(output_block*, bitpack_d*, location_t)’:
/export/gnu/import/git/sources/gcc/gcc/lto-streamer-out.c:189:55: internal
compiler error: in expand_call, at calls.c:3407
bp_pack_value (bp, ob->current_file != xloc.file, 1);
