I think we encode proligue and epilogues now for all targets.

It's been done for several targets, but when looking recently I got the
impression that it hadn't been done yet for SH, for example.

Any hints on what is missing or needs to be done for SH?

--- Comment #6 from Ian Lance Taylor <ian at airs dot com> ---
All the insns in sh_expand_epilogue need to be examined to see if they need
REG_CFA notes. Some of them already have them. I don't know what more are
needed.
For example, look at the changes made to the i386 backend when rth added the
general support for unwinding through epilogues:

Sort of, but not quite. 12990 does no cover the exception handling aspects,
but it claims that the problem persists target-independently for debug.
But this is not a problem for ia64. Since we have now the target-independent
infrastructure and one target port that uses it to handle this problem,
this has become a target problem; each target needs to be adjusted separately
to create the proper epilogue information, so it makes sense to track
progress (or lack thereof) for each target individually, while having
one meta-bug to keep track of them all.
Should I mark 12990 as blocking 29997, and 29998 as blocking 12990?
OTOH, when you read the description of 12990, it sounds like the problem
exists only for i[3456]86-*-*, so maybe we should add this to the target
field of 12990 and only make 12990 as blocking 29997.

I think this is really a dup of bug 12990.
