Well, I guess then the first thing to ask for is for both the
gcc.target/i386/opt-1.c and gcc.target/i386/opt-2.c tests to be
extended so that they are run with -fPIC. It would be helpful

I confirm the opt-1/opt-2 failures on i686-linix and x86_64-linux when using
-fpic or -fPIC:

The issue is not darwin-specific.

Can you try regressing r141079 and see if that suppresses the problem on -m32
for i686-apple-darwin9?

To clarify are you saying that the offending revision is likely 141079 or
141077? Both have changes to alias.c.

Both revisions are the same: 141077 is for trunk (what I build and probably you
also), 141079 is for

This revision is for the ira-merge branch, the revision for trunk is r141077
and given the revision window and the fact that it cannot be r141078 since the

Can you try the failing test cases with -fno-PIC to see if these issues are
related to the fact that darwin defaults to -fPIC?

I now get the same error for gcc.target/i386/opt-1.c and opt-2.c also in 32 bit
