Bug #: 53963
Summary: [4.8 Regression] LTO bootstrap failed with
bootstrap-profiled
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: hjl.tools@gmail.com
On Linux/x86-64, revision 189467 failed to profiledbootstrap:
checking for suffix of object files... configure: error: in
`/export/gnu/import/git/gcc-test-profile/bld/x86_64-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[5]: *** [configure-stagefeedback-target-libgcc] Error 1
when configured with
--prefix=/usr/local --enable-clocale=gnu --with-system-zlib --enable-sh
ared --with-demangler-in-ld --with-build-config=bootstrap-lto --with-fpmath=sse
"--prefix=/usr/local" is the key to trigger this regression.
The stage 3 compiler is miscompiled. Revision 189349 is OK.

I don' think so. I have configured as
../gcc-svn/trunk/configure --with-build-config=bootstrap-lto
--enable-languages=c
and fails as well. Backing out r189453 works OK.

I believe --prefix=/usr/local is the default. I didn't get this
failure with --prefix=/usr/gcc-4.8.0.

I am testing reverting:
