Include the language identifier emitted by gas in the set of ones where
no mangled names are expected. Even if there could be "hand-mangled"
names, gas doesn't emit DW_AT_linkage_name in the first place.
|
|
Prior to entering the enclosing "else if()" the earlier associated if()
checks function->is_linkage and, if set, uses function->name. The
comment in patch context precedes (and explains) the setting
function->is_linkage. Yet with the flag set, we should then also return
the function name, just like said earlier if() would do when we came
here a 2nd time for the same "addr". And indeed passing the same address
twice on addr2line's command line would resolve the function for the 2nd
instance, but not for the 1st (if this code path is taken). (This,
obviously, is particularly relevant when there's no ELF symbol table in
the first place, like would be the case - naturally - in PE/COFF
binaries, for example.)

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".
Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).
Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.
NM=my-nm now does a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM=/usr/bin/my-nm now avoids a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM="my-nm -p../wombat" now does a path search and runs e.g.
/usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)
Regenerate all affected configure scripts.
* libtool.m4 (LT_PATH_NM): Handle user-specified NM with
options, including options containing paths.

At least x86-64's x32 sub-mode and RISC-V's 32-bit mode calculate
addends as 64-bit values, but store them in signed 32-bit fields when
generating the file without encountering any earlier error. When the
relocated field is a 64-bit one, the value resulting after processing
the relocation record when linking (or the latest when loading) may
thus be wrong due to the truncation.
With the code change in place, one x32 testcase actually triggers the
new diagnostic. That one case of too large a (negative) addend is being
adjusted alongside the addition of a new testcase to actually trigger
the new error. (Note that due to internal BFD behavior the relocation in
.data doesn't get processed anymore after the errors in .text.)
Note that in principle it is possible to express 64-bit relocations in
ELF32, but this would require .rel relocations, i.e. with the addend
stored in the 64-bit field being relocated. But I guess it would be a
lot of effort for little gain to actually support this.
