Bug ID: 97855
Summary: [11 regression] Bogus warning locations during
lto-bootstrap
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: hubicka at gcc dot gnu.org
Target Milestone: ---
For a while we get odd looking locations:
D.5677.coeffs[0]’../../gcc/calls.c: In function ‘expand_call’:
../../gcc/dojump.c:118:28: warning: may be used uninitialized in this function
[-Wmaybe-uninitialized]
118 | pending_stack_adjust = save->x_pending_stack_adjust;
| ^
D.5677.coeffs[0]’../../gcc/calls.c:4082:34: note: was declared here
4082 | saved_pending_stack_adjust save;
| ^
D.5677.coeffs[0]’../../gcc/dojump.c:119:27: warning: may be used uninitialized
in this function [-Wmaybe-uninitialized]
119 | stack_pointer_delta = save->x_stack_pointer_delta;
| ^
D.5677.coeffs[0]’../../gcc/calls.c:4082:34: note: was declared here
4082 | saved_pending_stack_adjust save;
| ^
This is not due to parallel write and seems that location code somehow conclude
to output the additional D.5677.coeffs[0]’
