Bug ID: 102747
Summary: gcov returns 0 when invoked on gcda generated by
previous gcc version
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: chipitsine at gmail dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
we use several gcc versions, so we do not know whether particular "gcda" was
produced by gcc-N or gcc-M.
for example, mixing gcc11 and gcc12 together:
running gcov-12 on gcda produced by gcc-11
gcov a-hello.gcda
a-hello.gcno:version 'B12R', prefer 'B20 '
a-hello.gcno:no functions found
a-hello.gcda:version 'B12R', prefer version 'B20 '
No executable lines
$ echo $?
0
$
I'm fine with error itself, it is expected. However I beleive exit status
should be "1"
