[Bug rtl-optimization/23392] New: objc/execute/exceptions/foward-1.m fails with -funroll-loops -O3 -fgnu-runtime

[pinskia at gcc dot gnu dot org]

This PR is to record the following failures:

FAIL: objc/execute/exceptions/foward-1.m execution,  -O3 -fomit-frame-pointer -funroll-loops  
-fgnu-runtime
FAIL: objc/execute/exceptions/foward-1.m execution,  -O3 -fomit-frame-pointer -funroll-all-loops 
-finline-functions  -fgnu-runtime

I have not looked into what is causing the failure yet.

This fails at -O1 -frename-registers also.
We get a bus error.


In a way this almost be considered a regression as -frename-registers was enabled at -funroll-loops.

I think the dwarf-2 eh information is messed up.

It looks like it fails on all 32bit powerpcs:
