- Handle version 1a of NT_PRPSINFO notes which include the pr_pid field. - Replace patch-sigev with upstream version. Note that upstream GDB doesn't define SIGLIBRT on older OS versions, so do that in the port Makefile instead. - Use PT_GET_EVENT_MASK/PT_SET_EVENT_MASK (new in 12). - Fix a bug where fork and LWP events weren't enabled in new child processes when following child processes after a fork. - Handle "real" vfork done events via PTRACE_VFORK (new in 12).

commit bc7b765ab71f967eb2a9c3da111d7529eec46fbe

Pass SIGLIBRT directly to child processes.
|
|
|
|
FreeBSD's librt uses SIGLIBRT as an internal signal to implement
|
|
SIGEV_THREAD sigevent notifications. Similar to SIGLWP or SIGCANCEL
|
|
this signal should be passed through to child processes by default.
|
|
|
|
include/ChangeLog:
|
|
|
|
* signals.def: Add GDB_SIGNAL_LIBRT.
|
|
|
|
gdb/ChangeLog:
|
|
|
|
* common/signals.c (gdb_signal_from_host): Handle SIGLIBRT.
|
|
(do_gdb_signal_to_host): Likewise.
|
|
* infrun.c (_initialize_infrun): Pass GDB_SIGNAL_LIBRT through to
|
|
programs.
|
|
* proc-events.c (signal_table): Add entry for SIGLIBRT.
