2021-01-01Update copyright year range in all GDB filesJoel Brobecker1-1/+1
This commits the result of running gdb/copyright.py as per our Start of New Year procedure... gdb/ChangeLog Update copyright year range in copyright header of all GDB files.
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.

gdb/ChangeLog: Update copyright year range in all GDB files.
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.
