2020-06-17gdb, gdbserver: remove ARM regdat filesSimon Marchi8-235/+14
This patch removes the leftover regformats .dat files for the arm architecture. There are no longer relevant, since the arm architecture has been converted to use feature-based target-descriptions. These .dat files are used by GDBserver ports that still use static target descriptions. These .dat files are generated from corresponding .xml files in the features directory. And since the corresponding .xml files for these arm .dat files don't exist anymore, it is impossible to re-generated them. If you delete these .dat files and type "make" in the features directory, you'll get: make: *** No rule to make target '../regformats/arm/arm-with-iwmmxt.dat', needed by 'all'. Stop. So it removes the entries in the `WHICH` variable of gdb/features/Makefile. Finally, it removes the rule in gdbserver/Makefile to generate .cc files from `../gdb/regformats/arm/%.dat`. gdb/ChangeLog: * features/Makefile (WHICH): Remove arm files. * regformats/arm/arm-with-iwmmxt.dat: Remove. * regformats/arm/arm-with-neon.dat: Remove. * regformats/arm/arm-with-vfpv2.dat: Remove. * regformats/arm/arm-with-vfpv3.dat: Remove. gdbserver/ChangeLog: * Makefile.in (%-generated.cc: ../gdb/regformats/arm/%.dat): Remove.

2020-06-17gdb/features: remove rx.xml from XMLTOC listSimon Marchi2-1/+4
When trying to run `make` in the features directory, in a clean repo, we get: Makefile:254: warning: overriding recipe for target 'rx.c' Makefile:250: warning: ignoring old recipe for target 'rx.c' make: Nothing to be done for 'all'. The warnings come from the fact that `rx.xml` is present in two lists, causing two `rx.c` targets to be defined. It is ok for it to be in the FEATURES_XMLFILES list, as this architecture uses the "feature-based" target-descriptions. It shouldn't be in the XMLTOC list, as this is for architectures that define complete/static target descriptions as XML files. gdb/ChangeLog: * features/Makefile (XMLTOC): Remove rx.xml.

2020-06-17Pass INTERNAL_GDBFLAGS when executing GDBKeith Seitz2-1/+7
gdb.debuginfod/fetch_src_and_symbols.exp attempts to ascertain whether GDB was built with debuginfod support by executing "$GDB --configuration". That seems harmless enough. However, if GDB is not already installed on the host, the command will fail: $ ./gdb --config Exception caught while booting Guile. Error in function "open-file": No such file or directory: "/usr/share/gdb/guile/gdb/boot.scm" ./gdb: warning: Could not complete Guile gdb module initialization from: /usr/share/gdb/guile/gdb/boot.scm. Limited Guile support is available. Suggest passing --data-directory=/path/to/gdb/data-directory. Python Exception <class 'ModuleNotFoundError'> No module named 'gdb': ./gdb: warning: Could not load the Python gdb module from `/usr/share/gdb/python'. Limited Python support is available from the _gdb module. Suggest passing --data-directory=/path/to/gdb/data-directory. This GDB was configured as follows: configure --host=x86_64-redhat-linux-gnu --target=x86_64-redhat-linux-gnu [abbreviated output] The problem here is, of course, that while running in the test suite, we must pass INTERNAL_GDBFLAGS in order to pick up the --data-directory option. gdb/testsuite/ChangeLog 2020-06-17 Keith Seitz <keiths@redhat.com> * gdb.deuginfod/fetch_src_and_symbols.exp: Pass INTERNAL_GDBFLAGS when executing "gdb --configuration".

2020-06-17[gdb/testsuite] Remove dependence on tcl_unknownTom de Vries2-11/+34
In gdb_init we install a local version of ::unknown, which relies on ::tcl_unknown, which is defined by dejagnu. This proc may be moved into a namespace, or disappear altogether, as indicated by dejagnu maintainers, so we can't rely on it. Fix this by recreating tcl's version of unknown, and using that instead. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2020-06-17 Tom de Vries <tdevries@suse.de> * lib/gdb.exp (gdb_tcl_unknown): New proc. (gdb_init): Use gdb_tcl_unknown for ::unknown override. Make override conditional on presence of gdb_tcl_unknown. (gdb_finish): Make override undo conditional on presence of gdb_tcl_unknown.
2020-06-17Update thread_control_state::trap_expected commentsPedro Alves2-22/+9
The comments describing trap_expected are out of date. It predates displaced stepping and non-stop mode ("keep other threads stopped"). It predates stepping over watchpoints with breakpoints inserted (keep_going_pass_signal). Says the variable is cleared in normal_stop, when it isn't. This fixes it. gdb/ChangeLog: 2020-06-17 Pedro Alves <palves@redhat.com> * gdbthread.h (thread_control_state) <trap_expected> Update comments.

2020-06-17gdb: Convert language la_get_symbol_name_matcher field to a methodAndrew Burgess20-69/+151
This commit changes the language_data::la_get_symbol_name_matcher function pointer member variable into a member function of language_defn. There should be no user visible changes after this commit. Before this commit access to the la_get_symbol_name_matcher function pointer was through the get_symbol_name_matcher function, which looked something like this (is pseudo-code): <return-type> get_symbol_name_matcher (language_defn *lang, <other args>) { if (current_language == ada) current_language->la_get_symbol_name_matcher (<other args>); else lang->la_get_symbol_name_matcher (<other args>); } In this commit I moved the get_symbol_name_matcher as a non-virtual function in the language_defn base class, I then add a new virtual method that is only used from within get_symbol_name_matcher, this can then be overridden by specific languages as needed. So we now have: class language_defn { <return-type> get_symbol_name_matcher (<args>) { if (current_language == ada) return current_language->get_symbol_name_matcher_inner (<args>); else return this->get_symbol_name_matcher_inner (<args>); } virtual <return-type> get_symbol_name_matcher_inner (<args>) { .... } } gdb/ChangeLog: * ada-lang.c (ada_get_symbol_name_matcher): Update header comment.

2020-06-16Use macros for TUI window namesTom Tromey3-32/+41
Christian pointed out that tui-layout.c hard-codes various window names. This patch changes the code to use the macros from tui-data.h instead. For each window, I searched for uses of the name; but I only found any in tui-layout.c.

2020-06-16Fix crash when exiting TUI with gdb -tuiTom Tromey5-5/+29
PR tui/25348 points out that, when "gdb -tui" is used, then exiting the TUI will cause a crash. This happens because tui_setup_io stashes some readline variables -- but because this happens before readline is initialized, some of these are NULL. Then, when exiting the TUI, the NULL values are "restored", causing a crash in readline. This patch fixes the problem by ensuring that readline is initialized first. Back in commit 11061048d ("Give a name to the TUI SingleKey keymap"), a call to rl_initialize was removed from tui_initialize_readline; this patch resurrects the call, but moves it to the end of the function, so as not to remove the ability to modify the SingleKey map from .inputrc. gdb/ChangeLog 2020-06-16 Tom Tromey <tom@tromey.com> PR tui/25348: * tui/tui.c (tui_ensure_readline_initialized): Rename from tui_initialize_readline.

2020-06-16Add two missing return values in gdb.python/py-nested-maps.cusers/luisgpm/testGary Benson2-0/+8
Two functions in gdb.python/py-nested-maps.c are missing return values. This causes clang to fail to compile the file with the following error: warning: control reaches end of non-void function [-Wreturn-type] This commit fixes, by causing the two functions to return pointers to the objects they've just allocated and initialized. I didn't investigate how this test had been passing with other compilers; I'm assuming serendipity, that in each function the value to be returned was already in the register it would need to be in to be the function's return value. gdb/testsuite/ChangeLog: * gdb.python/py-nested-maps.c (create_map): Add missing return value.

2020-06-16x86: drop SSE4a from SSE check againJan Beulich6-11/+15
Upon re-consideration in commit 569d50f1c611 ("x86: further refine SSE check (SSE4a, SHA, GFNI)") I went too far: Mixing of SSE and AVX insns doesn't suffer as bad a penalty on AMD CPUs as on Intel ones. SSE4a being an AMD-only extension, it shouldn't be part of the ISA extensions set for which the diagnostic may get issued. Undo that part.

The PowerPC PE support is so old and bitrotted that it ought to be removed. Test results for a cross from x86_64 with no C cross compiler currently shows 109 fails. I don't think anyone cares about the target. This FIXME in bfd/peXXigen.c has been around since 1999, git commit 277d1b5e453: /* FIXME: This file has various tests of POWERPC_LE_PE. Those tests worked when the code was in peicode.h, but no longer work now that the code is in peigen.c. PowerPC NT is said to be dead. If anybody wants to revive the code, you will have to figure out how to handle those issues. */ and this one in gas/config/tc-ppc.c since 1995, git commit cd557d83d61: * FIXME: I just noticed this.
