[Bug target/18010] bad unwind info due to multiple returns (missing epilogue)

OK, I tried this patch on the CVS gcc-3_4_branch (the 4.0 branch didn't work at
all for me, even in it's pristine version).  As you said, the patch does fix the
bug I reported.  In addition, the test-suites report the following:

gcc Summary: 4 additional tests now pass (24083, up from 24079)
g++ Summary: 2 new unexpected failures (up from 0).
g77 Summary: no changes
objc Summary: no changes
libstdc++ Summary: no changes
libjava Summary: no changes

I'm not sure the g++ failures are real: if I try and cut & past one of the
failing commands myself, it works just fine.  For example, one of the failures is:

Executing on host: /home/davidm/src/gcc-build-p2/gcc/testsuite/../g++

WARNING: program timed out.

FAIL: g++.dg/template/access8.C (test for excess errors)

but when I run this by hand, it works just fine.

I'll see if I can figure out what's going on here tomorrow.
