Chris,
   How essential is r81455 to the llvm-gcc4.2-2.7 release? Can we regress it
out for 2.7? I've tried all of the suggestions in...

http://llvm.org/bugs/show_bug.cgi?id=6778

from Duncan for moving va_opt into darwin.c as an extern. While this
works at first glance, it destablizes the parallel make. Regressing r81455
doesn't appear to cause any problems.

[LLVMdev] darwin llvm-gfortran Polyhedron 2005 results

[CCing Dale since this was his change, not mine]

The change in 81455 fixes a compiler crash.  It doesn't happen very often,
but I can't imagine we would want to back that out.  Fixing it would be a
more reasonable solution.  From a quick look at it, the problem is that
gcc/config/darwin-c.c is registering va_opt for GC.  When you build for Fortran,
darwin-c.o is not linked so the GC gets confused somehow.

Bob,
    Duncan suggested moving va_opt into darwin.o and changing the declaration
from static to
extern in darwin-c.o. I have tried that here...

http://llvm.org/bugs/attachment.cgi?id=4652

in various forms. While the change seems to work for
a simple make, it breaks parallel builds...

http://llvm.org/bugs/show_bug.cgi?id=6778#c17

Do you have any suggestions for a change to the fortran build
to solve this? We can't link in darwin-c.o of course, but would
it make sense to have fortran declare it's own static copy of
va_opt somewhere?

[LLVMdev] darwin llvm-gfortran Polyhedron 2005 results

often, but I can't imagine we would want to back that out.  Fixing it would
be a more reasonable solution.  From a quick look at it, the problem is that
gcc/config/darwin-c.c is registering va_opt for GC.  When you build for Fortran,
darwin-c.o is not linked so the GC gets confused somehow.
This is the first I was aware this patch broke anything; nobody cc'd me on
the bugzilla, and I don't normally pay attention to Fortran mail.

We definitely don't want to revert 81455; the bug caused a crash building
something that's part of MacOS, and yes, that's more important than
Fortran.   But it should be possible to get Fortran to build.  I would think the
right idea is to change the build so that either darwin-c.o gets linked in
(theoretically wrong but it should work), or (better) gt_gcc–r_gt_darwin_c_h is
not referenced in Fortran.  It appears to be configured into gtype-fortran.h,
which is generated during the build, so the thing would be to get it not to go
in there....I'm not that expert with the GC mechanism, but I can play around
a little....

anyone has done *any* llvm-gfortran perf work.
