Bug ID: 69172
Summary: [6 Regression] ICE in make_ssa_name_fn, at
tree-ssanames.c:266
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at gcc dot gnu.org
Target Milestone: ---
r232077, powerpc64le-linux-gnu, works with -O2
reduced test case:
int a;
__inline __attribute__((__always_inline__)) void *mempcpy(void *p1, void *p2,
long p3) {
return __builtin___mempcpy_chk(p1, p2, p3, 0);
}
void sd_inode_set_vid() {
int *b = &a, *c = &a;
mempcpy(c, b, sizeof(int));
}
$ gcc -c -g -O3 sd_inode.i
sd_inode.i: In function 'sd_inode_set_vid':
sd_inode.i:10:1: internal compiler error: in make_ssa_name_fn, at
tree-ssanames.c:266
}
