--- Comment #1 from Sergio Durigan Junior <sergiodj at sergiodj dot net> ---
The formatting for the example snippet got messed up. Here's a fixed version:
$ echo 'int main(){}' > foo.c
$ ~/gcc/install/bin/gcc -c foo.c -O2 -g -flto=auto -ffat-lto-objects
-fdebug-prefix-map=`pwd`=/aaaaaaa -o foo
$ ~/gcc/install/bin/gcc foo -flto=auto -ffat-lto-objects -o bar
