Extended Description

simd-4.C from the gcc testsuite (g++.dg/eh) fails differently at
-O0 and at -O2 while with mainline you always get the llvm-gcc -O0
behaviour:

$ llvm-g++ -o simd-4 -O0 simd-4.C
$ ./simd-4
terminate called after throwing an instance of 'int'
Aborted (core dumped)

$ llvm-g++ -o simd-4 -O2 simd-4.C
$ ./simd-4
Aborted (core dumped)

Seems like good EH tests for Dale to look at. :-)

What's the status of this?

[llvmbot]

The test is ppc32-only, and is still broken. It is a perserve mix of Altivec and EH, and uses
-fnon-call-exceptions. I'm not sure we've implemented that.

[lattner]

-fnon-call-exceptions is tracked elsewhere.
