--- Comment #1 from joseph at codesourcery dot com  2012-10-25 22:06:51 UTC ---
My past messages to the various lists discuss the relevant issues.  I 
still think a combined binutils+gdb git repository (without any of the 
other pieces from the src repository) is probably the best trade-off.

http://sourceware.org/ml/gdb/2011-10/msg00134.html is one of my more 
recent messages on this subject (you'll find plenty more relevant 
information in that thread and in the other threads on the subject over 
the past several years on both binutils and GDB project list).

--- Comment #8 from Marek Polacek  2012-10-25

Ok, reproducible even on x86_64 Fedora 16 with trunk GCC.  I have built current
GCC trunk (just ../configure --prefix=`pwd` --enable-languages=c,c++
--disable-bootstrap) and current hjl/lto/master branch (just ../configure &&
make).  Then in ~/hbin2 I have newly built ld-new and a 'ld' script:
$ cat ~/hbin2/ld
#!/bin/sh
/home/marek/hbin2/ld-new --version
exec /home/marek/hbin2/ld-new "$@"

Now, it is needed to adjust ORIGINAL_LD_FOR_TARGET and
ORIGINAL_PLUGIN_LD_FOR_TARGET in ./gcc/collect-ld to point to newly built
ld-new, so e.g. "/home/marek/hbin2/ld".  Then just:
$ PATH=~/hbin2:$PATH ~/rh/x/trunk/gcc/g++ -B ~/rh/x/trunk/gcc -c -O2
-fno-early-inlining -flto pr13229.cc -m32
$ PATH=~/hbin2:$PATH ~/rh/x/trunk/gcc/g++ -B ~/rh/x/trunk/gcc -shared -O2 -fPIC
-flto -fuse-linker-plugin -nostdlib pr13229.o -m32

Tried also gcc-4_7 branch and the result is the same like above.
