            Bug ID: 27099
           Summary: -fsjlj-exceptions emitting _Unwind_Resume instead of
                    _Unwind_SjLj_Resume
           Product: clang
           Version: unspecified
          Hardware: Other
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

not sure if correct place to report bug. i don't have a non-apple clang version
to report against.

Version: Apple LLVM version 7.3.0 (clang-703.0.29)

if i specify a target triple with a system other than darwin along with
-fsjlj-exceptions, e.g.

clang++ -target armv7a-unknown-none-macho -arch armv7 -march=armv7-a
-mcpu=cortex-a5 -mfpu=vfpv4-d16 -Xclang -fsjlj-exceptions -E -dD - < /dev/null
| grep __USING_SJLJ_EXCEPTIONS__
#define __USING_SJLJ_EXCEPTIONS__ 1

i get the appropriate preprocessor define, but the output still makes
references to the incorrect _Unwind_Resume
000009ea        f7ffeb0a        blx     __Unwind_Resume

i am in this situation because this change:
http://reviews.llvm.org/D12155
made it so i can't specify hard-float and darwin at the same time. my platform
does have hard-float, but i need to continue using sjlj exceptions.
