2020-05-15Enable hardware breakpoints for gdbserver on WindowsHannes Domani1-0/+3
When trying to use hardware breakpoints with gdbserver you get this error: (gdb) hbreak main Hardware assisted breakpoint 2 at 0x40162d: file gdb-9493.c, line 5. (gdb) c Continuing. Warning: Cannot insert hardware breakpoint 2. Could not insert hardware breakpoints: You may have requested too many hardware breakpoints/watchpoints. It turns out the respective types just needed to be added to the appropriate callback functions, because x86_dr_(insert|remove)_watchpoint already handles them. gdbserver/ChangeLog: 2020-05-15 Hannes Domani <ssbssa@yahoo.de> * win32-i386-low.cc (i386_supports_z_point_type): Handle Z_PACKET_HW_BP z_type. (i386_insert_point): Handle raw_bkpt_type type. (i386_remove_point): Likewise.

gdbserver/ChangeLog: 2020-04-30 Hannes Domani <ssbssa@yahoo.de> * configure.srv <x86_64-*-mingw*, x86_64-*-cygwin*> (srv_tgtobj): Add arch/i386.o. * win32-arm-low.cc (arm_num_regs): New function.

2020-04-08Introduce win32_target_ops::decr_pc_after_breakTom Tromey1-0/+1
This adds a decr_pc_after_break member to win32_target_ops and updates the two Windows targets to set it. Note that I can't test the win32-arm-low.c change. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.h (struct win32_target_ops) <decr_pc_after_break>: New field. * win32-i386-low.c (the_low_target): Update. * win32-arm-low.c (the_low_target): Update.
2020-04-08Add read_pc / write_pc support to win32-lowTom Tromey1-0/+46
This changes win32-low.c to implement the read_pc and write_pc methods. A subsequent patch will need these. Note that I have no way to test, or even compile, the win32-arm-low.c change. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.h (win32_process_target::read_pc) (win32_process_target::write_pc): Declare. * win32-low.c (win32_process_target::read_pc) (win32_process_target::write_pc): New methods. * win32-i386-low.c (i386_win32_get_pc, i386_win32_set_pc): New functions. (the_low_target): Update. * win32-arm-low.c (arm_win32_get_pc, arm_win32_set_pc): New functions. (the_low_target): Update.
2020-04-08Wrap shared windows-nat code in windows_nat namespaceTom Tromey1-0/+2
This wraps the shared windows-nat code in a windows_nat namespace. This helps avoid name clashes. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c: Add "using namespace". * nat/windows-nat.h: Wrap contents in windows_nat namespace. * nat/windows-nat.c: Wrap contents in windows_nat namespace. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.h (struct win32_target_ops): Use qualified names where needed. * win32-i386-low.c: Add "using namespace". * win32-low.c: Add "using namespace". * win32-arm-low.c: Add "using namespace".
2020-04-08Change two windows_thread_info members to "bool"Tom Tromey1-3/+3
This changes a couple of fields of windows_thread_info to have type "bool". It also updates the comment of another field, to clarify the possible values it can hold. gdb/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * windows-nat.c (thread_rec) (windows_nat_target::fetch_registers): Update. * nat/windows-nat.h (struct windows_thread_info) <suspended>: Update comment. <debug_registers_changed, reload_context>: Now bool. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-i386-low.c (update_debug_registers) (i386_prepare_to_resume, i386_thread_added): Update.
2020-04-08Rename win32_thread_info to windows_thread_infoTom Tromey1-9/+9
This renames win32_thread_info to windows_thread_info in gdbserver. This renaming helps make it possible to share some code between gdb and gdbserver. gdbserver/ChangeLog 2020-04-08 Tom Tromey <tromey@adacore.com> * win32-low.h (struct windows_thread_info): Rename from win32_thread_info. Remove typedef. (struct win32_target_ops, win32_require_context): Update. * win32-low.c (win32_get_thread_context) (win32_set_thread_context, win32_prepare_to_resume) (win32_require_context, thread_rec, child_add_thread) (delete_thread_info, continue_one_thread) (child_fetch_inferior_registers, child_store_inferior_registers) (win32_resume, suspend_one_thread, win32_get_tib_address): Update. * win32-i386-low.c (update_debug_registers) (win32_get_current_dr, i386_get_thread_context) (i386_prepare_to_resume, i386_thread_added, i386_single_step) (i386_fetch_inferior_register, i386_store_inferior_register): Update. * win32-arm-low.c (arm_get_thread_context) (arm_fetch_inferior_register, arm_store_inferior_register): Update.
2020-02-13gdbserver: rename source files to .ccSimon Marchi1-0/+468
For the same reasons outlined in the previous patch, this patch renames gdbserver source files to .cc. I have moved the "-x c++" switch to only those rules that require it. gdbserver/ChangeLog: * Makefile.in: Rename source files from .c to .cc. * %.c: Rename to %.cc. * configure.ac: Rename server.c to server.cc. * configure: Re-generate.
