Re: [Patch, _eh, dawin, Version2] Allow targets to suppress epilogues in _eh frames.

Iain,
   I am also seeing the failure...

FAIL: gfortran.dg/g77/980701-0.f  -Os  execution test

at -m64 under this second revision of your _eh darwin
patch. This represents a regression from both current
gcc trunk and your previous _eh darwin patch...

http://gcc.gnu.org/ml/gcc-patches/2010-08/msg01037.html

when I tested against either the compatibility or compact
unwinders on x86_64-apple-darwin10 or against the compatibility
unwinder on i386-apple-darwin10.

It would appear that the second patch doesn't exactly reproduce
the behavior of the first. Can you break up the changes between
the first and second patches into sections to figure out which
part triggered the gfortran testsuite failure?
