Running the gcc testsuite I get the following ICE:

assert happens due on call of simplify_subreg the outermode is a BLKmode.

I think we should check within simplify_get_subreg for outermode == BLKmode and avoid calling of simplify_subreg for it.
Comment 2 Kai Tietz 2015-03-25 20:38:48 UTC 
As more I look as more I guess it is related to recent pic-code changes in i386.c for Darwin.
I will check at what places we now assume that for PIC (especially for UNSPEC UNSPEC_PCREL) we assume that x64-code only uses path with GOT-table for PIC.
