So, first I noticed:
[cgd@vader binutils]$ ./strip-new foobar
./strip-new: 'foobar': No such file
[cgd@vader binutils]$ echo $?
0
That didn't seem right. 8-)
I originally noticed this on RHEL4u3, but verified it exists in current head.
I then tracked this down to changes made on 2003-11-07, specifically objcopy.c
rev 1.56 and the related changes.
To verify that previously it would have returned a non-zero exit status, I
downloaded and tested binutils 2.14. (keep reading 8-)
Going from there and a quick M-x grep get_file_size, I noticed the following
exit status errors. I've provided comparison results from binutils 2.14 for
reference:
* ./strip-new nonex -> exit status 0. (was 127)
* ./objcopy --add-section foo=nonex -> exit status 0. (was 1)
* ./objcopy --keep-symbols nonex file.o file_new.o -> exit status 0 (was 1).
(I suspect other symbol-file-related flags would have similar issues, i.e.,
all callers of add_specific_symbols().)
* ./addr2line nonex -> exit status 0 (was 1)
* ./ranlib nonex -> exit status 0 (was 9)
* ./ranlib -t nonex -> exit status 0 (was 1)
* ./objdump -x nonex -> exit status 0 (was 1)
* ./size nonex -> exit status 0 (was 1)
The following still exit with an error status:
* ./nm nonex
* ./objcopy nonex nonex2 -- but this reports that input file 'nonex' is
empty... right after saying that there's no such file.
These issues seem to have been introduced in the commits on 2003-11-07 around
12:19 UTC. Specific revisions:
* objcopy.c 1.56
* addr2line.c 1.20
etc., i.e., the commits with the ChangeLog entry:
2003-11-07 Jonathan R. Grant <
jg-binutils@...>
* bucomm,c (get_file_size): New function. Returns the size of a
file.
* bucomm.h: Add prototype for get_file_size.
* addr2line.c (process_file): Use new function.
* ar.c (main, ranlib_only, ranlib_touch): Likewise.
* nm.c (display_file): Likewise.
* objcopy.c (add_specific_symbols, copy_file, strip_main,
copy_main): Likewise.
* objdump.c (display_file): Likewise.
* size.c (display_file): Likewise.
* strings.c (strings_file): Likewise.
* readelf.c (process_file): Use similar code to get_file_size.
(committed by nickc).
Sorry, I don't have patches. (I've got other fish to fry at the moment, and I
can't use a patched binutils in my project anyway. I also don't have a valid
assignment on file at this point, either.)
Hopefully I've at least provided enough info to make it easy for somebody else
to resolve these issues quickly/easily...
