Bug ID: 67157
Summary: Compiling gcc6 with liblto_plugin, v5.2.0
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: dilyan.palauzov at aegee dot org
Target Milestone: ---
I have ld.bfd/as 2.25.51.20150808 and the most recent gcc repository.
I do /git/gcc/configure --enable-host-shared --enable-threads=posix
--with-arch=haswell --enable-__cxa_atexit --enable-languages=c,c++,lto,jit
--enable-targets=all --enable-nls --with-linker-hash-style=gnu
--with-system-zlib --disable-multilib --prefix=/usr/local/gcc60 .
For the compilation I use gcc 5.2.0 .
If I have in /usr/local/gcc60/etc/config.site:
export CFLAGS="-pipe -O3 -flto -fno-fat-lto-objects"
export CXXFLAGS="${CFLAGS}"
export LDFLAGS="-Wl,-O1,-z,relro,-s -flto=4"
then building gcc fails at stage1 with the message below. However, if I have
no /usr/local/gcc60/etc/config.site then the build works. I guess that the
problem is not with the linker, but with liblto-5.2.0.
