2022-04-28Remove "typedef enum ..."Tom Tromey1-2/+2
I noticed a few spots in GDB that use "typedef enum". However, in C++ this isn't as useful, as the tag is automatically entered as a typedef. This patch removes most uses of "typedef enum" -- the exceptions being in some nat-* code I can't compile, and glibc_thread_db.h, which I think is more or less a copy of some C code from elsewhere. Tested by rebuilding.
2022-02-11gdb: extend the information printed by 'maint info jit'Jan Vrany1-2/+11
This commit updates the output of 'maint info jit' to print not just the jit_code_entry address, but also the symfile address, and the symfile size. The new information could be obtained by looking into target memory at the contents of the jit_code_entry, but, by storing this information within gdb at the time the jit object is loaded, it is now possible to check if the jit_code_entry has been modified in target memory behind gdb's back. Additionally, the symfile address is the same address that is now used in the objfile names after commit 4a620b7e. One test that relies on the output of 'maint info jit' was updated to allow for the new output format.

2020-12-04gdb: add inferior_execd observableSimon Marchi1-7/+0
I want to add another action (clearing displaced stepping state) that happens when an inferior execs. I think it would be cleaner to have an observer for this event, rather than have infrun know about each other sub-component. Replace the calls to solib_create_inferior_hook and jit_inferior_created_hook in follow_exec by observers. gdb/ChangeLog: * observable.h (inferior_execd): Declare new observable. * observable.c (inferior_execd): Declare new observable. * infrun.c (follow_exec): Notify inferior_execd observer. * jit.c (jit_inferior_created_hook): Make static. (_initialize_jit): Register inferior_execd observer. * jit.h (jit_inferior_created_hook): Remove declaration. * solib.c (_initialize_solib): Register inferior_execd observer. Change-Id: I000cce00094e23baa67df693d912646b6ae38e44
2020-10-25gdb: make jit.c use the inferior_created inferior parameterSimon Marchi1-1/+2
Use the inferior parameter now available in jit_inferior_created_hook. It is passed down to jit_inferior_init, which uses it as much as possible instead of the current inferior or current program space. gdb/ChangeLog: * jit.c (jit_reader_load_command): Pass current inferior. (jit_inferior_init): Change parameter type to inferior, use it. (jit_inferior_created): Remove. (jit_inferior_created_hook): Pass inferior parameter down. (_initialize_jit): Use jit_inferior_created_hook instead of jit_inferior_created. * jit.h (jit_inferior_created_hook): Add inferior parameter. * infrun.c (follow_exec): Pass inferior to jit_inferior_created_hook.

2020-07-22gdb/jit: remove jiter_objfile_data -> objfile back-linkSimon Marchi1-7/+0
This is no longer needed, remove it. gdb/ChangeLog: 2020-07-22 Simon Marchi <simon.marchi@polymtl.ca> * jit.h (struct jiter_objfile_data) <jiter_objfile_data, objfile>: Remove. * jit.c (get_jiter_objfile_data): Update.
2020-07-22gdb/jit: move cached_code_address and jit_breakpoint to jiter_objfile_dataSimon Marchi1-0/+8
This is in preparation for allowing more than one JITer objfile per program space. Once we do that, each JITer objfile will have its own JIT breakpoint (on the __jit_debug_register_code function it provides). The cached_code_address field is just the runtime / relocated address of that symbol. Since they are going to become JITer-objfile-specific and not program-space-specific, move these fields from jit_program_space_data to jiter_objfile_data. gdb/ChangeLog: 2020-07-22 Simon Marchi <simon.marchi@polymtl.ca> * jit.h (struct jiter_objfile_data) <cached_code_address, jit_breakpoint>: Move to here from ... * jit.c (jit_program_space_data): ... here. (jiter_objfile_data::~jiter_objfile_data): Update. (jit_breakpoint_deleted): Update. (jit_breakpoint_re_set_internal): Update.
2020-07-22gdb/jit: split jit_objfile_data in twoSimon Marchi1-11/+17
The jit_objfile_data is currently used to hold information about both objfiles that are the result of JIT compilation (JITed) and objfiles that can produce JITed objfiles (JITers). I think that this double use of the type is confusing, and that things would be more obvious if we had one type for each role. This patch splits it into: - jited_objfile_data: for data about an objfile that is the result of a JIT compilation - jiter_objfile_data: for data about an objfile which produces JITed objfiles There are now two JIT-related fields in an objfile, one for each kind. With this change, the following invariants hold: - an objfile has a non-null `jiter_data` field iff it defines the required symbols of the JIT interface - an objfile has a non-null `jited_data` field iff it is the product of JIT compilation (has been produced by some JITer) gdb/ChangeLog: 2020-07-22 Simon Marchi <simon.marchi@polymtl.ca> * jit.h (struct jit_objfile_data): Split into... (struct jiter_objfile_data): ... this ... (struct jited_objfile_data): ... and this. * objfiles.h (struct objfile) <jit_data>: Remove. <jiter_data, jited_data>: New fields. * jit.c (jit_objfile_data::~jit_objfile_data): Rename to ... (jiter_objfile_data::~jiter_objfile_data): ... this. (get_jit_objfile_data): Rename to ... (get_jiter_objfile_data): ... this. (add_objfile_entry): Update. (jit_read_descriptor): Use get_jiter_objfile_data. (jit_find_objf_with_entry_addr): Use objfile's jited_data field. (jit_breakpoint_re_set_internal): Use get_jiter_objfile_data. (jit_inferior_exit_hook): Use objfile's jited_data field.
2020-07-22gdb/jit: link to jit_objfile_data directly from the objfile structSimon Marchi1-0/+29
Remove the use of objfile_data to associate a jit_objfile_data with an objfile. Instead, directly link to a jit_objfile_data from an objfile struct. The goal is to eliminate unnecessary abstraction. The free_objfile_data function naturally becomes the destructor of jit_objfile_data. However, free_objfile_data accesses the objfile to which the data is attached, which the destructor of jit_objfile_data doesn't have access to. To work around this, add a backlink to the owning objfile in jit_objfile_data. This is however temporary, it goes away in a subsequent patch. gdb/ChangeLog: 2020-07-22 Simon Marchi <simon.marchi@polymtl.ca> * jit.h: Forward-declare `struct minimal_symbol`. (struct jit_objfile_data): Migrate to here from jit.c; also add a constructor, destructor, and an objfile* field. * jit.c (jit_objfile_data): Remove. (struct jit_objfile_data): Migrate from here to jit.h. (jit_objfile_data::~jit_objfile_data): New destructor implementation with code moved from free_objfile_data. (free_objfile_data): Delete. (get_jit_objfile_data): Update to use the jit_data field of objfile. (jit_find_objf_with_entry_addr): Ditto. (jit_inferior_exit_hook): Ditto. (_initialize_jit): Remove the call to register_objfile_data_with_cleanup. * objfiles.h (struct objfile) <jit_data>: New field.
2020-07-22gdb/jit: pass the jiter objfile as an argument to jit_event_handlerTankut Baris Aktemur1-2/+5
This is a refactoring that adds a new parameter to the `jit_event_handler` function: the JITer objfile. The goal is to distinguish which JITer triggered the JIT event, in case there are multiple JITers -- a capability that is added in a subsequent patch. gdb/ChangeLog: 2020-07-22 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * jit.h: Forward-declare `struct objfile`. (jit_event_handler): Add a second parameter, the JITer objfile. * jit.c (jit_read_descriptor): Change the signature to take the JITer objfile as an argument instead of the jit_program_space_data. (jit_inferior_init): Update the call to jit_read_descriptor. (jit_event_handler): Use the new JITer objfile argument when calling jit_read_descriptor. * breakpoint.c (handle_jit_event): Update the call to jit_event_handler to pass the JITer objfile.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
