[Bug c/34185] New: -Os seems to be broken on alpha

[oliver at linux-kernel dot at]

I had trouble building firefox on alpha. In the first moment I thought it's a
binutils bug, since when I add --no-relax to ld, the build goes trough.
However, the produced result doesn't actually work.

In http://sources.redhat.com/bugzilla/show_bug.cgi?id=5276#c6, H.J.Lu tought it
might be a compiler bug and Jay Estabrook gave me the hint to use -O2 instead
of -Os and that actually worked fine.

Another ref to the rhbz# https://bugzilla.redhat.com/show_bug.cgi?id=379551

You can find a build.log of a try to build firefox with -Os here:

If you need any additional information, please let me know!
