Fix makefile

WIP on python scripting

Implement custom pretty-printing of varobj using Python code.

Pretty raw, in particular memory management is a mess.

Update

Update

Update stored value when format changes.

* varobj.c (varobj_set_display_format): Recomputed
print_value.
(c_value_of_variable): Return print_value.

Update

Update

Make mi_cmd_break_insert exception-safe.

[gdb]
* breakpoint.c (break_command_1): Return void.
(break_command_really): Return void.  Rethrow
exceptions instead of returning.
(gdb_breakpoint): Remove the error_message parameter.
Return void.  Rename to set_breakpoint.
* gdb.h (gdb_breakpoint): Rename and move to...
        * breakpoint.h (set_breakpoint): ...here.
* mi/mi-cmb-break.c (mi_cmd_break_insert): Restore
event hooks even if exception is thrown.  Adjust to
gdb_breakpoint interface changes.

[gdb/testsuite]
* gdb.mi/basic.c (return_1): New function.
* gdb.mi/mi-break.exp: Make sure that failed -break-insert
don't cause future evaluations of function to report
creation of internal breakpoints.

Update

Update

Rethrow exception properly.

[gdb]
        Properly rethrow exception.  This fixes errors
about non-existent functions for -break-insert.

* breakpoint.c (break_command_really): Use throw_exception
for rethrowing.  If rethrowing, don't print the exception.

[gdb/testsuite]
* gdb.mi/mi-break.exp (test_error): New.
Call it.

Update

Update

Update

Use vector for varobj_list_children interface.

* gdb/varobj.c (varobj_list_children): Return vector
of varobjs.
* gdb/varobj.h (varobj_list_children): Adjust
prototype.
(varobj_p): Declare.  Declare vector thereof.
* mi/mi-cmd-var.c (mi_cmd_var_list_children): Adjust
for varobj_list_children change.

Update

Update

Use multiple locations for hardware watchpoints.

This eliminates the need to traverse value chain, doing
various checks, in three different places.

* breakpoint.h (struct bp_location): New fields
lengths and watchpoint_type.
(struct breakpoint): Remove the val_chain field.
* breakpoint.c (is_hardware_watchpoint): New.
(free_valchain): Remove.
(update_watchpoint): New.
(insert_bp_location): For hardware watchpoint, just
directly insert it.
(insert_breakpoints): Call update_watchpoint_locations
on all watchpoints.  If we have failed to insert
any location of a hardware watchpoint, remove all inserted
locations.
(remove_breakpoint): For hardware watchpoints, directly
remove location.
(watchpoints_triggered): Iterate over locations.
(bpstat_stop_status): Use only first location of
a resource watchpoint.
(delete_breakpoint): Don't call free_valchain.
(print_one_breakpoint): Don't print all
locations for watchpoints.
(breakpoint_re_set_one): Use update_watchpoint for
watchpoints.

testsuite/
* gdb.base/watchpoint-solib.exp: New.
* gdb.base/watchpoint-solib.c: New.
* gdb.base/watchpoint-solib-shr.c: New.

Update

Don't reset watchpoint block on solib load.

* breakpoint.c (insert_bp_location): For watchpoints,
recompute condition.
(breakpoint_re_set_one): Instead of recomputing value
and condition for watchpoints, just reset value and
let insert_breakpoints/insert_bp_location recompute it.
Don't do anything about disabled watchpoint.

Inform about new thread in a single place.

don't try to increment PC by hand.

Update

Update

Handle solaris dynamic linker name change.

Ignore change in name of dynamic linker during
execution.  This also unbreaks pending breakpoints.

This macros has added in 1999 and used by
config/pa/nm-hppah.h. The latter file was itself
deleted in 2004, so now target_pid_or_tid_to_str
is always the same as target_pid_to_str.

* gdb/target.h (target_pid_or_tid_to_str): Remove.

Update

Update

Update

Make insert_breakpoints return void.

* breakpoint.h (insert_breakpoints): Change
return type to void.
* breakpoint.c (insert_breakpoints): Change
return type to void.  Rename local return_val
variable to error.

return value from insert_breakpoints, catch exception.

Update

Stop infrun from tracking breakpoint insertion status.

The checks of breakpoints_inserted before calling remove_breakpoints
are removed, as remove_breakpoint won't touch uninserted breakpoints.
In a number of places, we're interested if a breakpoint is inserted
at particular PC, and we now use breakpoint_inserted_here_p.  In a few
places, insert_breakpoints can be called unconditionally, since it
won't try to insert already inserted breakpoint.

* breakpoint.h (regular_breakpoint_inserted_here_p): New
declaration.
* breakpoint.c (regular_breakpoint_inserted_here_p): New.
(breakpoint_inserted_here_p): Use
regular_breakpoint_inserted_here_p.
* infrun.c (breakpoints_inserted): Remove.
(resume): Don't check for breakpoints_inserted before
remove_hw_watchpoints. Use breakpoint_inserted_here_p.
(proceed, init_wait_for_inferior): Don't set breakpoints_inserted.
(handle_inferior_event): Don't use breakpoints_inserted.
Use breakpoints_meant_to_be_inserted and
breakpoints_inserted_here_p.
(insert_step_resume_breakpoint_at_sal, keep_going): Use
breakpoints_meant_to_be_inserted. Don't set breakpoints_inserted.
(normal_stop): Don't check for breakpoints_inserted.  Don't
set breakpoints_inserted.
(keep_going): Don't check for breakpoints_inserted.

        breakpoints

comments.

Make disable_breakpoints_in_unloaded_shlib static.

* breakpoint.c (disable_breakpoints_in_unloaded_shlib):
Make static.

Update

Remove unused breakpoint fields.

* breakpoint.h (struct breakpoint): Remove
