This commit updates the copyright year in some files where
we have a copyright year outside of the copyright year,
and thus are not included in gdb's copyright.py script.
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
sec->output_section will be NULL when objcopy removes sections.
* coff-rs6000.c (_bfd_xcoff_copy_private_bfd_data): Protect against
objcopy removing sections.
The idea of this patch is to make it easy to see which targets (just
sparc) have ELF_MINPAGESIZE != ELF_COMMONPAGESIZE.
* elf32-arm.c (ELF_MINPAGESIZE): Don't define.
* elf32-metag.c: Likewise.
* elfnn-aarch64.c: Likewise.
* elf64-x86-64.c: Likewise. Also don't redefine a bunch of other
macros for l1om elf64-target.h use that are unchanged from default.
avr_io_reg_read_command is an ordinary gdb command, and so should not
be calling reinitialize_more_filter. This patch removes it. I'm
checking this in as obvious. Tested by rebuilding.
COFF_WITH_pex64 and COFF_WITH_peAArch64 can't be true at the same time.
That means that two conditionals that control the sorting of the .pdata section
became a falsum.
The testsuite doesn't catch this because the linker does the sorting and to link
you require library support from the unwinder so we can't test from binutils in
isolation.

* peXXigen.c: Fix conditional.
"show" command callbacks, like most ordinary gdb commands, should use
filtered output. I found a few that did not, so this patch changes
them to use the filtered form.
I happened to notice that one "show" callback was printing to
gdb_stdout rather than to the passed-in ui_file parameter. I went
through all such callbacks and fixed them to consistently use the
ui_file.
Regression tested on x86-64 Fedora 34.
This changes index-cache.c to use debug_prefixed_printf_cond_nofunc.
As a side effect, logs are now written to gdb_stdlog. This is part of
PR gdb/7233.

This changes machoread.c to use debug_prefixed_printf_cond_nofunc. As
a side effect, the logs are now written to gdb_stdlog. This is part
of PR gdb/7233.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=7233
The process record code often emits unfiltered output. In some cases,
this output ought to go to gdb_stderr (but see below). In other
cases, the output is guarded by a logging variable and so ought to go
to gdb_stdlog. This patch makes these changes.
Note that in many cases, the output to stderr is followed by a
"return -1", which is how process record indicates an error. It seems
to me that calling error here would be preferable, because, in many
cases, that's all the caller does when it sees a -1. However, I
haven't made this change.
This is part of PR gdb/7233.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=7233
I noticed yesterday that if gdb output is redirected to a file, the
pager will still be active. This is irritating, because the output
isn't actually visible -- just the pager prompt. Looking in bugzilla,
I found that this had been filed 17 years ago, as PR cli/8798.
This patch fixes the bug. It changes the pagination code to query the
particular ui-file to see if paging is allowable. The ui-file
implementations are changed so that only the stdout implementation and
a tee (where one sub-file is stdout) can page.
Regression tested on x86-64 Fedora 34.
Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=8798
gdbtypes.h uses core_addr_eq and core_addr_hash in a weird way: taking
the address of a member and then passing this (as a void*) to these
functions.
It seems better to simply inline the ordinary code here. CORE_ADDR is
a scalar so it can be directly compared, and the identity hash
function seems safe to assume as well.
After this, core_addr_eq and core_addr_hash are unused, so this patch
removes them.
This commit ensures that the following settings are cloned from one
inferior to the new one when processing the clone-inferior command:
- inferior-tty
- environment variables
- cwd
- args
Some of those parameters can be passed as command line arguments to GDB
(-args and -tty), so one could expect the clone-inferior to respect
those flags. The following debugging session illustrates that:
gdb -nx -quiet -batch \
-ex "show args" \
-ex "show inferior-tty" \
-ex "clone-inferior" \
-ex "inferior 2" \
-ex "show args" \
-ex "show inferior-tty" \
-tty=/some/tty \
-args echo foo bar
Argument list to give program being debugged when it is started is "foo bar".
Terminal for future runs of program being debugged is "/some/tty".
[New inferior 2]
Added inferior 2.
[Switching to inferior 2 [<null>] (/bin/echo)]
Argument list to give program being debugged when it is started is "".
Terminal for future runs of program being debugged is "".
The other properties this commit copies on clone (i.e. CWD and the
environment variables) are included since they are related (in the sense
that they influence the runtime behavior of the program) even if they
cannot be directly set using command line switches.
There is a chance that this patch changes existing user workflow. I
think that this change is mostly harmless. If users want to start a new
inferior based on an existing one, they probably already propagate those
settings to the new inferior in some way.
Tested on x86_64-linux.

In some cases, eg. riscv_pre_output_hook, gas generates out-of-order
relocations. Various places in the linker assume relocs are sorted
by increasing r_offset, which is normally the case. Provide
GAS_SORT_RELOCS to handle unsorted relocs.

various i386-aout and i386-coff target removal
Also tidies some other aout leftovers in binutils-common.exp.
gdb_print_host_address is just a simple wrapper around
fprintf_filtered. However, it is readily replaced in all callers by a
combination of %s and call to host_address_to_string. This also
simplifies the code, so I think it's worthwhile to remove this
function.
Regression tested on x86-64 Fedora 64.
gdb_bfd.c contains most of gdb's BFD-related utility functions.
However, gdb_bfd_errmsg is in utils.c. It seemed better to me to move
this out of util.[ch] and into the BFD-related file instead.
Tested by rebuilding.
Maskray (Fangrui Song) had suggested me before that we should combine
multiple testcases into one file as possible as we can. So that we can
more easily understand what these test cases are testing, and easier to
maintain. Therefore, this patch rewrites all csr testcases, to make them
more clean.

H-ext).

Set of fixes to resolve some duplicate test names in the gdb.mi/
directory. There should be no real test changes after this set of
fixes, they are all either:
- Adding with_test_prefix type constructs to make test names unique,
or
- Changing the test name to be more descriptive, or better reflect
the test being run.
