Description Dominique d'Humieres 2014-06-23 19:34:19 UTC

The tests gcc.c-torture/compile/pr34856.c and gcc.dg/pr34856.c fail on powerpc-apple-darwin9 with -O2 and above and -m32. The ICE is

/opt/gcc/work/gcc/testsuite/gcc.dg/pr34856.c:29:1: internal compiler error: in simplify_immed_subreg, at simplify-rtx.c:5333

Revision r209530 is OK, r210534 is not, likely a wide-int fallout.

The test gcc.dg/pr34856.c also fails on powerpc64-unknown-linux-gnu (see https://gcc.gnu.org/ml/gcc-testresults/2014-06/msg02026.html).

seen on non-darwin too.
