>Description:
gcc.c-torture/compile/simd-5.c fails with an ICE for an
unrecognized instruction with mainline, 3.3-branch, and
3-2.branch for powerpc64-linux, either a cross compiler or
a native 64-bit compiler. Compiler output:
simd-5.c: In function `main':
simd-5.c:12: error: unrecognizable insn:
(insn 68 67 33 0 (nil) (set (subreg:DI (reg:V2SI 9 r9) 0)
(subreg:DI (mem:V2SI (plus:DI (reg/f:DI 31 r31)
(const_int 136 [0x88])) [0 S8 A8]) 0)) -1 (nil)
(nil))
simd-5.c:12: internal compiler error: in extract_insn, at recog.c:2175
Please submit a full bug report,
Full text of the test case:
#define vector64 __attribute__((vector_size(8)))
main(){
vector64 int c;
vector64 int a = {1, -1};
vector64 int b = {2, -2};
c = -a + b*b*(-1LL);
/* c is now {5, 3} */
printf("result is %llx\n", (long long)c);
}
