Bug ID: 104677
Summary: With -fprofile-arcs, the name of the .gcda file is
incorrect
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: vincent-gcc at vinc17 dot net
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Under Debian/unstable, if I do "gcc foo.c -o foo2 -fprofile-arcs", the name of
the .gcda file is "foo2-foo.gcda" instead of "foo.gcda".
The behavior is correct until GCC 10.3.0, but it is incorrect with GCC 11.2.0
and
gcc-12 (Debian 12-20220222-1) 12.0.1 20220222 (experimental) [master
r12-7325-g2f59f067610].
The current gcc/doc/invoke.texi documentation for -fprofile-arcs contains:
Each object file's @var{auxname} is generated from the name of the output file,
if explicitly specified and it is not the final executable, otherwise it is the
basename of the source file.
but this has not changed since GCC 9 at least. Here, foo2 is the final
executable (but why the word "final"?), so that one should be in the
"otherwise" case.
