Bug ID: 90944
Summary: combine debug file created when it shouldn't be
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: bergner at gcc dot gnu.org
Target Milestone: ---
If we have a test case that dies very early before expand, we still end up with
a stub combine debug file, even though we never called combine(). For example:
bergner@pike:~/$ echo "error stuff" > bug.i
bergner@pike:~/$ /path/to/gcc/xgcc -B/path/to/gcc -S -O1 -da bug.i
bug.i:1:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ at end of
input
1 | stuff
| ^~~~~
bergner@pike:~/$ cat bug.i.264r.combine
;; Combiner totals: 0 attempts, 0 substitutions (0 requiring new space),
;; 0 successes.
