2024-03-26gdb, gdbserver, gdbsupport: remove includes of early headersSimon Marchi1-1/+0
Now that defs.h, server.h and common-defs.h are included via the `-include` option, it is no longer necessary for source files to include them. Remove all the inclusions of these files I could find. Update the generation scripts where relevant. Change-Id: Ia026cff269c1b7ae7386dd3619bc9bb6a5332837 Approved-By: Pedro Alves <pedro@palves.net>
2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
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.
2021-11-18gdbsupport: make gdb_assert_not_reached accept a format stringSimon Marchi1-2/+2
Change gdb_assert_not_reached to accept a format string plus corresponding arguments. This allows giving more precise messages. Because the format string passed by the caller is prepended with a "%s:" to add the function name, the callers can no longer pass a translated string (`_(...)`). Make the gdb_assert_not_reached include the _(), just like the gdb_assert_fail macro just above. Change-Id: Id0cfda5a57979df6cdaacaba0d55dd91ae9efee7

2020-10-09gdb: Delay releasing target_desc_up in more casesAndrew Burgess1-11/+14
After commit: commit 51a948fdf0e14fb69ab9e0c79ae8b2415801f9a3 Date: Mon Jul 20 14:18:04 2020 +0100 gdb: Have allocate_target_description return a unique_ptr There were a few places where we could (should?) have delayed releasing the target_desc_up until a little later. This commit catches these cases. In the case of ARC, the target_desc_up is now exposed right out to gdbserver, which means making a small change there too. There should be no user visible changes after this commit. gdb/ChangeLog: * arch/aarch32.c (aarch32_create_target_description): Release the target_desc_up as late as possible. * arch/aarch64.c (aarch64_create_target_description): Likewise. * arch/amd64.c (amd64_create_target_description): Likewise. * arch/arc.c (arc_create_target_description): Return a target_desc_up, don't release it. * arch/arc.h (arc_create_target_description): Update declaration.

2020-10-08gdb: Have allocate_target_description return a unique_ptrAndrew Burgess1-1/+1
Update allocate_target_description to return a target_desc_up, a specialisation of unique_ptr. This commit does not attempt to make use of the unique_ptr in the best possible way, in almost all cases we immediately release the pointer from within the unique_ptr and then continue as before. There are a few places where it was easy to handle the unique_ptr, and in these cases I've done that. Everything under gdb/features/* is auto-regenerated. There should be no user visible changes after this commit. gdb/ChangeLog: * arch/aarch32.c (aarch32_create_target_description): Release unique_ptr returned from allocate_target_description. * arch/aarch64.c (aarch64_create_target_description): Likewise. * arch/amd64.c (amd64_create_target_description): Likewise. * arch/arc.c (arc_create_target_description): Likewise. * arch/arm.c (arm_create_target_description): Likewise. * arch/i386.c (i386_create_target_description): Likewise. * arch/riscv.c (riscv_create_target_description): Update return type.

2020-10-07arc: Rename "arc_gdbarch_features" structShahab Vahedi1-6/+6
"arc_gdbarch_features" is a data structure containing information about the ARC architecture: ISA version, register size, etc. This name is misleading, because although it carries the phrase "gdbarch", it has nothing to do with the type/interface in GDB. Traditionaly, "gdbarch" structures are only used for that purpose. To rectify this, this patch changes the name to "arc_arch_features". gdb/ChangeLog: * arch/arc.h: Rename "arc_gdbarch_features" to "arc_arch_features". * arc-tdep.h: Likewise. * arc-tdep.c: Likewise.
2020-08-25arc: Add ARCv2 XML target along with refactoringShahab Vahedi1-22/+86
A few changes have been made to make the register support simpler, more flexible and extendible. The trigger for most of these changes are the remarks [1] made earlier for v2 of this patch. The noticeable improvements are: - The arc XML target features are placed under gdb/features/arc - There are two cores (based on ISA) and one auxiliary feature: v1-core: ARC600, ARC601, ARC700 v2-core: ARC EM, ARC HS aux: common in both - The XML target features represent a minimalistic sane set of registers irrespective of application (baremetal or linux). - A concept of "feature" class has been introduced in the code. The "feature" object is constructed from BFD and GDBARCH data. It contains necessary information (ISA and register size) to determine which XML target feature to use. - A new structure (ARC_REGISTER_FEATURE) is added that allows providing index, names, and the necessity of registers. This simplifies the sanity checks and future extendibility. - Documnetation has been updated to reflect ARC features better. - Although the feature names has changed, there still exists backward compatibility with older names through find_obsolete_[core,aux]_names() functions. The last two points were inspired from RiscV port. [1] https://sourceware.org/pipermail/gdb-patches/2020-May/168511.html gdb/ChangeLog: * arch/arc.h (arc_gdbarch_features): New class to stir the selection of target XML. (arc_create_target_description): Use FEATURES to choose XML target. (arc_lookup_target_description): Use arc_create_target_description to create _new_ target descriptions or return the already created ones if the FEATURES is the same. * arch/arc.c: Implementation of prototypes described above. * gdb/arc-tdep.h (arc_regnum enum): Add more registers. (arc_gdbarch_features_init): Initialize the FEATURES struct. * arc-tdep.c (*_feature_name): Make feature names consistent. (arc_register_feature): A new struct to hold information about registers of a particular target/feature. (arc_check_tdesc_feature): Check if XML provides registers in compliance with ARC_REGISTER_FEATURE structs. (arc_update_acc_reg_names): Add aliases for r58 and r59. (determine_*_reg_feature_set): Which feature name to look for. (arc_gdbarch_features_init): Given MACH and ABFD, initialize FEATURES. (mach_type_to_arc_isa): Convert from a set of binutils machine types to expected ISA enums to be used in arc_gdbarch_features structs. * features/Makefile (FEATURE_XMLFILES): Add new files. * gdb/features/arc/v1-aux.c: New file. * gdb/features/arc/v1-aux.xml: Likewise. * gdb/features/arc/v1-core.c: Likewise. * gdb/features/arc/v1-core.xml: Likewise. * gdb/features/arc/v2-aux.c: Likewise. * gdb/features/arc/v2-aux.xml: Likewise. * gdb/features/arc/v2-core.c: Likewise. * gdb/features/arc/v2-core.xml: Likewise. * NEWS (Changes since GDB 9): Announce obsolence of old feature names. gdb/doc/ChangeLog: * gdb.texinfo (Synopsys ARC): Update the documentation for ARC Features. gdb/testsuite/ChangeLog: * gdb.arch/arc-tdesc-cpu.xml: Use new feature names.
2020-03-16arc: Migrate to new target featuresAnton Kolesov1-0/+58
This patch replaces usage of target descriptions in ARC, where the whole description is fixed in XML, with new target descriptions where XML describes individual features, and GDB assembles those features into actual target description. v2: Removed arc.c from ALLDEPFILES in gdb/Makefile.in. Removed vim modeline from arc-tdep.c to have it in a separate patch. Removed braces from one line "if/else". Undid the type change for "jb_pc" (kept it as "int"). Joined the unnecessary line breaks into one line. No more moving around arm targets in gdb/features/Makefile. Changed pattern checking for ARC features from "arc/{aux,core}" to "arc/". v3: Added include gaurds to arc.h. Added arc_read_description to _create_ target descriptions less. v4: Got rid of ARC_SYS_TYPE_NONE. Renamed ARC_SYS_TYPE_INVALID to ARC_SYS_TYPE_NUM. Fixed a few indentations/curly braces. Converted arc_sys_type_to_str from a macro to an inline function. gdb/ChangeLog: 2020-03-16 Anton Kolesov <anton.kolesov@synopsys.com> Shahab Vahedi <shahab@synopsys.com> * Makefile.in: Add arch/arc.o * configure.tgt: Likewise. * arc-tdep.c (arc_tdesc_init): Use arc_read_description.
