Bug ID: 94144
Summary: ICE on aarch64-linux-gnu: in aarch64_print_operand at
gcc/config/aarch64/aarch64.c:9528
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: andrea.corallo at arm dot com
Target Milestone: ---
The compiler get ICE in final when compiling at -O3 the code below.
Note: this appears to be a regression to gcc 9.
---
int a, b, z;
int c(int d, int e) { return d && e > 0 && d > 5 - e ? 0 : d + e; }
int k();
void h(int);
void f(short d) {
int g = !(0 < d);
h(d);
if (b) {
unsigned i[1];
i[0] = g = 0;
for (; g <= 8; g++)
d || k();
if (c(!(i[0] <= z) >= d, d) != a)
k();
}
}
---
during RTL pass: final
test.c: In function ‘f’:
test.c:20:1: internal compiler error: in aarch64_print_operand, at
