Bug ID: 90972
Summary: [9 Regression] ICE in fold_convert_loc, at
fold-const.c:2429
Product: gcc
Version: 9.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at debian dot org
Target Milestone: ---
gdb with some multilibs enabled ftbfs with gcc-9 r on powerpc64le-linux-gnu.
Work around is to build with -O2. can be seen with a native and a cross
compiler.
$ cat cpu-i386.i
long f;
void a();
void *g() {
char h[] = {}, j[] = {}, k[] = {}, l[] = {}, m[] = {}, n[] = {}, o[] = {},
q[] = {}, r[] = {};
static const char i[] = {6, 0};
const char *nops[] = {h, i, j, k, l, m, n, o, q, r};
long s = 2;
void *fill = a;
char *p = fill;
while (f) {
void *b = p;
const void *c = nops[1];
long d = s, e = __builtin_object_size(b, 0);
__builtin___memcpy_chk(b, c, d, e);
p += s;
f -= s;
}
return fill;
}
