* target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
* target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook. * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with code which looks for those two waitkinds. Use switch statement. * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with CHILD_SPECIAL_WAITSTATUS.

* target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
|
||||
* target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
|
||||
* infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
|
||||
code which looks for those two waitkinds. Use switch statement.
|
||||
* config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
|
||||
CHILD_SPECIAL_WAITSTATUS.
|
||||
|
||||
* procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
|
||||
* Move target_signal_from_host, target_signal_to_host, and
|
||||
store_waitstatus from inftarg.c to target.c. procfs needs them.
|
||||
* target.c: Include "wait.h" and <signal.h>.
|
||||
* target.h, infrun.c (proceed), proceed callers: Pass new code
|
||||
TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
|
||||
enums being treated as unsigned and is cleaner.
|
||||
* infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
|
||||
TARGET_SIGNAL_0.
|
||||
* infcmd.c (signal_command), infrun.c (signals_info):
|
||||
Don't allow user to specify numeric equivalent of
|
||||
TARGET_SIGNAL_DEFAULT.
