[llvm-commits] PATCH: Partial fix for PR13641

[William J. Schmidt]

This small patch addresses the most crucial part of PR13641 (missing
traceback table for powerpc64-unknown-linux-gnu).  The four bytes of
zeroes following the function body are used by GDB to detect the end of
the function.  Although the following eight bytes of traceback
information are listed as mandatory in the PPC64 ELF ABI, GDB does not
currently use this data, so it's not urgent to fix this part.  I've
included a small test case as well.

No new failures in the regression tests or the app/benchmarks
test-suite.  If this is ok for the trunk, I'd appreciate it if someone
could commit it for me.  I don't yet have commit authority.

Thanks!
Bill
