Bug ID: 90308
Summary: ICE in output_operand: invalid %-code
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Following is causing ICE:
$ cat align.c
void a() {}
int b;
char *c;
void d() { __builtin_memcpy(c, &b, sizeof 0); }
$ arm-linux-gnueabi-gcc -mflip-thumb -mcpu=arm1136j-s -munaligned-access
align.c
during RTL pass: final
align.c: In function ‘d’:
align.c:4:1: internal compiler error: output_operand: invalid %-code
4 | void d() { __builtin_memcpy(c, &b, sizeof 0); }
