--- Comment #4 from Mark Millard <markmi at dsl-only.net> ---
Warning: clang 3.8.0 (and likely before) has various problems for powerpc (and
sometimes powerpc64) code generation:

I modify signal delivery in my powerpc FreeBSD builds to have a so-called
"red-zone" to avoid the following powerpc ABI-violation issue. (powerpc64
already has "red-zone" use because that is part of the powerpc64 ABI used by
FreeBSD.)

Some parts of the following item apply to more general code generation contexts
than just exception-handling, although it started with finding
exception-handling examples.

https://llvm.org/bugs/show_bug.cgi?id=26856

The below 2 are for exception-handling code generation issues (counting
.eh_frame information as code).

The 1 item below was fixed in 3.8.0 rc3 but not in rc2 or earlier versions.

(All these submittals to llvm.org came from attempting to use clang 3.8.0 for
TARGET_ARCH=powerpc buildworld on an old PowerMac. As I remember all of the
above seemed to be long-standing issues, not recent regressions. There are some
matching FreeBSD submittals but until things change at llvm.org. . .)
