And indeed, it doesn't work the other way round... [carrying on from your
testcase:]
dk@mace /artimi/firmware/test> mv foo.exe foo
dk@mace /artimi/firmware/test> rm gmon.out
dk@mace /artimi/firmware/test> ./foo
dk@mace /artimi/firmware/test> gprof foo.exe
foo.exe: No such file or directory
dk@mace /artimi/firmware/test> gprof foo
Flat profile:
Exe magic is not applied to command line arguments by the shell, otherwise
it might mangle plaintext or options: exe magic is applied when an
application tries to open a file that doesn't exist. gprof doesn't open foo
or foo.exe; it opens gmon.out. The exe magic would have to modify the
contents of gmon.out in accord with gprof's internal binary format to make a
difference here.
cheers,
