Bug ID: 82112
Summary: internal compiler error: in fold_convert_loc, at
fold-const.c:2262
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: noloader at gmail dot com
Target Milestone: ---
I'm working on GCC112 (gcc112.fsffrance.org on the compile farm).
$ cat test.cxx
#include <altivec.h>
typedef unsigned char byte;
typedef vector unsigned char uint8x16_p8;
typedef vector unsigned long long uint64x2_p8;
#define ALIGN_DATA(n) __attribute__((aligned(n)))
int main(int argc, char* argv[])
{
ALIGN_DATA(16) const byte c[16] = {
0,1,2,3, 4,5,6,7, 8,9,10,11, 12,13,14,15
};
const uint64x2_p8 mask = vec_ld(0, c);
return 0;
}
