New L modifier for ar q operation to flatten archives.
binutils/
* doc/binutils.texi (ar cmdline): Document L modifier for q operation.
* NEWS: Mention that.
* ar.c (flatten_archives): New variable.
(usage): Describe L.
(decode_options): Parse L.
(replace_members): Use L.
gas/write.c provides a fallback TC_VALIDATE_FIX_SUB define that can be
a problem for some targets, the problem being that a non-zero
definition of TC_VALIDATE_FIX_SUB says that some uses of fx_subsy are
OK, in effect that the target will handle fx_subsy in md_apply_fix
and/or tc_gen_reloc. A lot of targets don't have the necessary
md_apply_fix and tc_gen_reloc support. So a safer default is to
disallow fx_subsy by default.
I've had a good look over target usage of fx_subsy, and think I've
caught all the cases where targets need TC_VALIDATE_FIX_SUB. Possible
failures would be limited to alpha, microblaze, ppc and s390 (the
targets that define UNDEFINED_DIFFERENCE_OK), or targets that generate
fixups with BFD_RELOC_GPREL32/16 and use a syntax explicitly showing
a difference expression.
* write.c (TC_VALIDATE_FIX_SUB): Default to 0.
* config/tc-hppa.h (TC_VALIDATE_FIX_SUB): Define.
* config/tc-microblaze.h (TC_VALIDATE_FIX_SUB): Define.
* config/tc-alpha.h (TC_VALIDATE_FIX_SUB): Define for ECOFF.
* config/tc-ppc.h (TC_VALIDATE_FIX_SUB): Don't define for ELF.
Do define for XCOFF.

objdump: add DWARF support for AIX
DWARF sections have special names on AIX which need be handled
by objdump in order to correctly print them.
This patch also adds the correlation in bfd for future uses.
When running test-case gdb.base/gold-gdb-index.exp on openSUSE Tumbleweed,
I run into:
...
FAIL: gdb.base/gold-gdb-index.exp: maint info symtabs
...
This is due to a dummy .gdb_index:
...
Contents of the .gdb_index section:
Version 7
CU table:
TU table:
Address table:
Symbol table:
...
The dummy .gdb_index is ignored when loading the symbols, and instead partial
symbols are used. Consequently, we get the same result as if we'd removed
-Wl,--gdb-index from the compilation.
Presumably, gold fails to generate a proper .gdb_index because it lacks
DWARF5 support.
Anyway, without a proper .gdb_index we can't test the gdb behaviour we're
trying to excercise. Fix this by detecting whether we actually used a
.gdb_index for symbol loading.
Tested on x86_64-linux.
gdb/testsuite/ChangeLog:
2021-07-14 Tom de Vries <email address hidden>
* lib/gdb.exp (have_index): New proc.
* gdb.base/gold-gdb-index.exp: Use have_index.
When building gdb with --disable-tui, we run into:
...
(gdb) frame apply all -- -^M
Undefined command: "-". Try "help".^M
(gdb) ERROR: Undefined command "frame apply all -- -".
UNRESOLVED: gdb.base/options.exp: test-frame-apply: frame apply all -- -
...
Fix this by detecting whether tui is supported, and skipping the tui-related
tests otherwise. Same in some gdb.tui test-cases.
Tested on x86_64-linux.
gdb/testsuite/ChangeLog:
2021-07-13 Tom de Vries <email address hidden>
* gdb.base/options.exp: Skip tui-related tests when tui is not
supported.
* gdb.python/tui-window-disabled.exp: Same.
* gdb.python/tui-window.exp: Same.

While testing the NixOS[1] packaging for gdb-11.0.90.tar.xz, I got the
following error:

In the nix build environment, /usr/bin/env is not present, only /bin/sh
is. This patch makes sure that gdb/make-init-c uses '/bin/sh' as
interpreter as this is the only one available on this platform.
I do not think this change will cause regressions on any other
configuration.
