Bug ID: 59326
Summary: FAIL: gcc.dg/vect/vect-simd-clone-*.c
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dominiq at lps dot ens.fr
CC: jakub at gcc dot gnu.org
The tests gcc.dg/vect/vect-simd-clone-*.c fail along two lines
(1) see http://gcc.gnu.org/ml/gcc-testresults/2013-11/msg02083.html
FAIL: gcc.dg/vect/vect-simd-clone-1.c -flto -ffat-lto-objects (internal
compiler error)
FAIL: gcc.dg/vect/vect-simd-clone-1.c -flto -ffat-lto-objects (test for excess
errors)
UNRESOLVED: gcc.dg/vect/vect-simd-clone-1.c -flto -ffat-lto-objects compilation

FAIL: gcc.dg/vect/vect-simd-clone-9.c -flto -ffat-lto-objects (internal
compiler error)
FAIL: gcc.dg/vect/vect-simd-clone-9.c -flto -ffat-lto-objects (test for excess

UNRESOLVED: gcc.dg/vect/vect-simd-clone-9.c -flto -ffat-lto-objects compilation
failed to produce executable
The ICE is of the kind
/opt/gcc/_clean/gcc/testsuite/gcc.dg/vect/vect-simd-clone-1.c:56:1: internal
compiler error: tree code 'omp_clause' is not supported in LTO streams
These ICEs can be silenced with a line such as
/* { dg-skip-if "" { *-*-* } { "-flto" } { "" } } */
I have no idea about the short-term plans, but it seems that a regular
error/sorry would be better.
(2) With -fopenmp-simd, AVX instructions are always emitted even on target that
does not support it, see
http://gcc.gnu.org/ml/gcc-testresults/2013-11/msg02085.html
