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).
