Bug ID: 99784
Summary: `labels as values`can point to the wrong spot after
optimization
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: mh+gcc at glandium dot org
Target Milestone: ---
Reduced testcase:
```
extern void bar();
extern void qux(void*);
void foo() {
bar();
here:
qux(&&here);
}
```
Resulting code at -O2:
```
foo():
.LFB0:
.L2:
sub rsp, 8
call bar()
.LVL0:
mov edi, OFFSET FLAT:.L2
add rsp, 8
jmp qux(void*)
```
IOW, the pointer that qux gets is that of a location before the call to bar!
