/* This include file defines the interface between the main part
|
|
|
|
|
of the debugger, and the part which is target-specific, or
|
|
|
|
|
specific to the communications interface between us and the
|
|
|
|
|
target.
|
|
|
|
|
|
|
|
|
|
A TARGET is an interface between the debugger and a particular
|
|
|
|
|
kind of file or process. Targets can be STACKED in STRATA,
|
|
|
|
|
so that more than one target can potentially respond to a request.
|
|
|
|
|
In particular, memory accesses will walk down the stack of targets
|
|
|
|
|
until they find a target that is interested in handling that particular
|
|
|
|
|
address. STRATA are artificial boundaries on the stack, within
|
|
|
|
|
which particular kinds of targets live. Strata exist so that
|
|
|
|
|
people don't get confused by pushing e.g. a process target and then
|
|
|
|
|
a file target, and wondering why they can't see the current values
|
|
|
|
|
of variables any more (the file target is handling them and they
|
|
|
|
|
never get to the process target). So when you push a file target,
|
|
|
|
|
it goes into the file stratum, which is always below the process
|
|
|
|
|
stratum. */

(1) This set of signals represents a widely-accepted attempt to

|
|
represent events of this sort in a portable fashion, (2) we want a
|
|
|
|
|
signal to make it from wait to child_wait to the user intact, (3) many
|
|
|
|
|
remote protocols use a similar encoding. However, it is
|
|
|
|
|
recognized that this set of signals has limitations (such as not
|
|
|
|
|
distinguishing between various kinds of SIGSEGV, or not
|
|
|
|
|
distinguishing hitting a breakpoint from finishing a single step).
|
|
|
|
|
So in the future we may get around this either by adding additional
|
|
|
|
|
signals for breakpoint, single-step, etc., or by adding signal
|
|
|
|
|
codes; the latter seems more in the spirit of what BSD, System V,

etc. are doing to address these issues. */

/* post process changes to signal handling in the inferior. */
|
|
|
|
|
|
* target.h: Add enum target_waitkind, enum target_signal, and
struct target_waitstatus. Change status argument to target_wait to
be struct target_waitstatus * instead of int *.
* target.h, infrun.c, all targets: Change type of signal arguments
to resume(), proceed(), and target_resume() from int to enum
target_signal.
* All targets (*_wait, *_resume): Change accordingly.
* infcmd.c (program_info, signal_command), throughout infrun.c,
* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
signal code stuff right with the new signals would be non-trivial).
* inferior.h (stop_signal): Make it enum target_signal not int.
* target.c, target.h (target_signal_to_string, target_signal_to_name,
target_signal_from_name): New functions.
* inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
store_waitstatus): New functions.
* procfs.c (procfs_notice_signals): Use them.
* i960-tdep.c (i960_fault_to_signal): New function, to replace
print_fault.
* config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
