Bug ID: 61589 Summary: [4.10 Regression] FAIL: (gcc.c-torture/compile|gcc.dg)/pr34856.c on powerpc-apple-darwin9 with -O2 and above Product: gcc Version: 4.10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: dominiq at lps dot ens.fr CC: iains at gcc dot gnu.org, mrs at gcc dot gnu.org Host: powerpc-apple-darwin9 Target: powerpc-apple-darwin9 Build: powerpc-apple-darwin9 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).
