* [gdb/testsuite] Set remotedir by default in some boardsTom de Vries2023-03-173-16/+77
| | | | | | | | | | | | | | | | When doing a gdb_simple_compile, and downloading the resulting exec $obj to target the result $target_obj may be a relative file path, which may give problems when trying to do: ... remote_exec target $target_obj ... Fix/workaround this on some target boards by setting remotedir by default, and add a corresponding test in gdb.testsuite/board-sanity.exp. This doesn't work for host/target board local-remote-host-native, so xfail this. Tested on x86_64-linux.
* [gdb/testsuite] Fix have_avx for remote targetTom de Vries2023-03-171-5/+10
| | | | | | | | | | | | | | In proc have_avx we compile some source into an exec, resulting in a file $obj on build, and then attempt to execute it on target: ... set result [remote_exec target $obj] ... Fix this by using gdb_remote_download target. Likewise in a few other procs that use "remote_exec target". Tested on x86_64-linux.
* [gdb/testsuite] Handle precise-aligned-alloc.c for remote hostTom de Vries2023-03-175-2/+22
| | | | | | | | | | | | | | | | | With test-case gdb.arch/i386-sse.exp (and likewise gdb.arch/i386-avx.exp) and host board local-remote-host-notty and target board native-gdbserver I run into: ... gdb compile failed, i386-sse.c:68:10: fatal error: \ ../lib/precise-aligned-alloc.c: No such file or directory #include "../lib/precise-aligned-alloc.c" ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ... Fix this using '#include "precise-aligned-alloc.c"' and making that work with non-remote and remote host. Tested on x86_64-linux.

* [gdb/testsuite] Add escape_for_hostTom de Vries2023-03-171-1/+11
| | | | | | | | | | | | | | | | | | | In gdb_compile we have: ... lappend new_options "ldflags=-Wl,-rpath,\\\$ORIGIN" ... and we could improve readability by using {} rather than "": ... lappend new_options {ldflags=-Wl,-rpath,\$ORIGIN} ... But rather than manually adding escapes in a string, add a new proc escape_for_host that care of this for us, allowing us to write: ... lappend new_options [escape_for_host {ldflags=-Wl,-rpath,$ORIGIN}] ... Tested on x86_64-linux.

* gas: apply md_register_arithmetic also to unary '+'Jan Beulich2023-03-172-11/+16
| | | | | | | | | | | | | | Even a unary '+' has to be considered arithmetic; at least on x86 in Intel Syntax mode otherwise bogus insn operands may be accepted. Convert this specific case to binary + (i.e. 0 + <register>). (An implication is that md_operator(,1,) would need to deal with arch- specific equivalents of unary '+' is a similar way, if such an arch- specific variant would be specified in the first place.) To avoid duplicating what make_expr_symbol() does to construct a constant-zero expression, simply make its previously local variable a file-scope static one. This way there's also no need to invoke clean_up_expression().
* gas: expose flag_macro_alternate globallyJan Beulich2023-03-175-33/+20
| | | | | | | | Yet again with the removal of gasp about 20 years ago this extra level of indirection isn't necessary anymore either. Drop macro.c's local variable and make as.c's global. While doing the conversion, switch the variable to "bool".
* gas: use flag_mri directly in macro processingJan Beulich2023-03-174-39/+23
| | | | | | Again with the removal of gasp about 20 years ago the extra level of indirection isn't necessary anymore. Drop macro.c's local variable and use the global flag directly.
* gas: isolate macro_strip_at to macro.cJan Beulich2023-03-173-9/+4
| | | | | | | This removes a leftover from i960 support; with that nothing is left which would set macro_strip_at to non-zero, so the variable is converted to a #define (retaining the logic in case a new user would appear) and macro_init()'s respective parameter is dropped.
* gas: drop function pointer parameter from macro_init()Jan Beulich2023-03-173-40/+16
| | | | | | With the removal of gasp (about 20 years ago) the need for this kind- of-hook has disappeared. Go a step beyond merely moving the to be called function: Inline its contents right at the sole call site.
* [gdb/testsuite] Fix filename in gdb.debuginfod/crc_mismatch.expTom de Vries2023-03-171-1/+1
| | | | | | | | | | | | | | | | After running test-case gdb.debuginfod/crc_mismatch.exp, I find a dir called '$': ... $ ls $build/gdb/testsuite/ $ config.log gdb.log lib outputs site.exp cache config.status gdb.sum Makefile site.bak temp ...

* gdb/doc: extended documentation for inferior function callsAndrew Burgess2023-03-161-0/+32
| | | | | | | | | | I noticed that the documentation for inferior function calls doesn't say much about what happens if/when an inferior function call is interrupted, i.e. it doesn't describe what the dummy frame looks like on the stack, or how GDB behaves when the inferior is continued and reaches the dummy frame. This commit aims to add some of this missing information.
* Fix build breakage in rs6000-aix-tdep.cTom Tromey2023-03-162-5/+6

* Re: Add --enable-linker-version optionChristophe Lyon2023-03-162-2/+2
| | | | | | | | | | | | | | | | | | | | The recently-added ld-version*.d tests expect .*GNU ld \(GNU Binutils\) 2.* in the .comment section. However, when buidling --with-pkgversion=XXX, we get GNU ld (XXX) 2.[...] instead, leading to a spurious FAIL. This small patch replaces "GNU Binutils" with ".*" instead. I inspected other testcases to see if we already had similar occurrences but I couldn't see any, so I hope this fix is OK for the purpose? Thanks, Christophe
* gdb/doc: spring clean the Python unwinders documentationAndrew Burgess2023-03-161-39/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation for the Python Unwinders API could do with some improvement. The 'Unwinder Skeleton Code' has an error: it says 'unwinders' when it should say 'unwinder' in one case. Additionally, by placing the 'Unwinder Skeleton Code' before the section 'Registering an Unwinder' we have skipping including the registration line in the skeleton code. But this is confusion for users (I think) as the skeleton code is almost complete, except for one missing line which the user has to figure out for themselves. By reordering the sections, it is now obvious that the registration should be included in the skeleton code, and the example is therefore almost complete. Additionally, in the example skeleton code the way in which the frame-id was being built (using the current stack point and program counter is (a) not correct, and (b) counter to what is laid out in the 'Unwinder Input' section when describing building a frame-id. I've removed the incorrect code and replaced it with more generic comments indicating what needs to be done. As the actual actions that need to be performed are both architecture specific, and dependent on the function being unwound, it's almost impossible to include more exact code here, but I think what I'm proposing is less misleading than what we had before. I've also added more cross references. Reviewed-By: Eli Zaretskii <eliz@gnu.org>

* Implement DAP variables, scopes, and evaluate requestsTom Tromey2023-03-147-21/+459
| | | | | | | | | | | | The DAP code already claimed to implement "scopes" and "evaluate", but this wasn't done completely correctly. This patch implements these and also implements the "variables" request. After this patch, variables and scopes correctly report their sub-structure. This also interfaces with the gdb pretty-printer API, so the output of pretty-printers is available.
* Hide the implementation of gdb_mpfTom Tromey2023-03-142-6/+13
| | | | | | | | | | This renames the data member of gdb_mpf and makes it private. It also adds a single new method to aid in this change. Unlike the earlier changes here, I did this one all together because gdb_mpf has very few uses.
* Rename gdb_mpq::val and make contents privateTom Tromey2023-03-142-43/+47
| | | | | | | | This changes gdb_mpq to hide its data, and renames the data member from 'val' to 'm_val', following gdb convention.
* Add operators and methods to gdb_mpqTom Tromey2023-03-144-37/+100
| | | | | | | | | | | This adds some operators and methods to gdb_mpq, in preparation for making its implementation private. This only adds the operators currently needed by gdb. More could be added as necessary.
* Rename gdb_mpz::val and make contents privateTom Tromey2023-03-142-55/+61
| | | | | | | | This changes gdb_mpz to hide its data, and renames the data member from 'val' to 'm_val', following gdb convention.
* Add methods and operators to gdb_mpzTom Tromey2023-03-146-61/+140
| | | | | | | | | | | This adds various methods and operators to gdb_mpz, as a step toward hiding the implementation. This only adds the operators that were needed. Many more could be added as required.
* Clean up gmp-utils.h includesTom Tromey2023-03-143-2/+2
| | | | | | | | | gmp-utils.h includes "defs.h", but normally the rule in gdb is that the .c files include this first. This patch changes this code to match the rest of gdb.
* Fix DAP frame bug with older versions of PythonTom Tromey2023-03-141-18/+15
| | | | | | | | | | Tom de Vries pointed out that one DAP test failed on Python 3.6 because gdb.Frame is not hashable. This patch fixes the problem by using a list to hold the frames. This is less efficient but there normally won't be that many frames. Tested-by: Tom de Vries <tdevries@suse.de>
