non-aligned watchpoints: insertion, deletion, and counting. If
|
||||
called with wp_count as the first argument, return the count of

||||
(go32_remove_aligned_watchpoint): New function, modeled after

|
||||
regions of arbitrary length by calling
|
||||
go32_handle_nonaligned_watchpoint as needed.
|
||||
(go32_region_ok_for_watchpoint): New function, called from
|
||||
can_use_hardware_watchpoint via the new macro

parentheses.

enable print-out depending on an environment variable GDB_SHOW_DR.
|
||||
(go32_insert_aligned_watchpoint): Look for an occupied debug
|
||||
register with the same address and access/length bits, and reuse
|
||||
it by incrementing reference the count, before occupying another
|
||||
register. Return zero upon success.
|
||||
(go32_insert_nonaligned_watchpoint): Pass the read/write bits to
|
||||
go32_remove_watchpoint.
|
||||
(go32_remove_watchpoint): Accept an additional parameter: the
|
||||
read/write bits of the watchpoint to remove, and only remove a
|
||||
watchpoint if it's occupied and its address and read/write bits
|
||||
match. Only disable the register if its reference count is zero;
|
||||
otherwise just decrease the reference count.
|
||||
(go32_remove_hw_breakpoint): Only decrease reference count and
|
||||
disable the debug register if it is occupied and its access bits
|
||||
match those of an instruction breakpoint.
|
||||
(go32_insert_hw_breakpoint): Before occupying another debug
|
||||
register, look for an already occupied register that defines an
|
||||
instruction breakpoint with the same address. If found, increment
|
||||
its reference count. Call SHOW_DR even if failed to insert a
|
||||
breakpoint.
|
||||
|
||||
* config/i386/nm-go32.h (target_remove_watchpoint): Accept the
|
||||
TYPE argument as well.

@subsection Function Prototypes
|

|
||||
Prototypes must be used to @emph{declare} functions but never to
|
||||
Prototypes must be used to @emph{declare} functions, and may be used to
|
||||
@emph{define} them. Prototypes for GDB functions must include both the
|
||||
argument type and name, with the name matching that used in the actual
|
||||
function definition.
|
||||
|
||||
For the sake of compatibility with pre-ANSI compilers, define prototypes
|
||||
with the @code{PARAMS} macro:
|
||||
|
||||
@example @code
|
||||
extern int memory_remove_breakpoint PARAMS ((CORE_ADDR addr,
|
||||
char *contents_cache));
|
||||
@end example
|
||||
|
||||
Note the double parentheses around the parameter types. This allows an
|
||||
arbitrary number of parameters to be described, without freaking out the
|
||||
C preprocessor. When the function has no parameters, it should be
|
||||
described like:
|
||||
|
||||
@example @code
|
||||
extern void noprocess PARAMS ((void));
|
||||
@end example
|
||||
|
||||
The @code{PARAMS} macro expands to its argument in ANSI C, or to a
|
||||
simple @code{()} in traditional C.
|
||||
|
||||
All external functions should have a @code{PARAMS} declaration in a
|
||||
header file that callers include, except for @code{_initialize_*}
|
||||
functions, which must be external so that @file{init.c} construction
|
||||
works, but shouldn't be visible to random source files.
