I get this when trying to compile scummvm with LTO and whole-program:
$ /usr/lib/gcc-snapshot/bin/g++ --version
g++ (Ubuntu/Linaro 20110813-1ubuntu1) 4.7.0 20110813 (experimental) [trunk
revision 177733]
$ CC=/usr/lib/gcc-snapshot/bin/gcc CXX=/usr/lib/gcc-snapshot/bin/g++
CFLAGS="-Ofast -flto" CXXFLAGS="-Ofast -flto" LDFLAGS="-flto -fwhole-program"
./configure
[...]
$ make -j9
[...]
RANLIB base/libbase.a
LINK scummvm
lto1: internal compiler error: in generate_canonical_option, at
opts-common.c:303
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-snapshot/README.Bugs> for instructions.
lto-wrapper: /usr/lib/gcc-snapshot/bin/g++ returned 1 exit status
/usr/bin/ld.bfd.real: lto-wrapper failed
collect2: error: ld returned 1 exit status
Removing -fwhole-program and changing the CXXFLAGS to -O1 doesn't change the
behaviour. I can attach a tarball if downloading the latest scummvm tarball is
too bothersome.
Note that I'm not using that dump-ipa-graph option at all.
