--- Comment #193 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
I am building firefox with -O3 and get no undefined symbols.  Can you, please,
relink with -Wl,--no-demangle --save-temps -fdump-ipa-all and try to look up
the missing symbol in -lm.res file and if it not UNDEF there make somewhere
available the dumps?
If it is undefined there, it may be firefox bug..
