From: Mark Kettenis Date: Sat, 26 Feb 2000 15:04:30 +0000 (+0000) Subject: 2000-02-26 Mark Kettenis X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=942fd805e449dc8c9747ae343f66f0e98f5e5ece;p=binutils-gdb.git 2000-02-26 Mark Kettenis * gnu-nat.c: Include "gdbthread.h". Include . Reorder headers a bit. Overall cleanup and minor reformatting. (MIG_SERVER_DIED): Remove define. (proc_update_sc): Add braces to silence compiler warning. (proc_steal_exc_port): Initialize err to zero. (make_proc): Add braces to silence compiler warning. (inf_validate_task_sc): Add cast to silence compiler warning. (inf_set_traced): Reorganize a bit to silence compiler warning. (inf_validate_procs): Use mach_msg_type_number_t for all thread numbers and add braces to silence compiler warning. (gnu_wait): Add prototypes for server functions and add braces to silence compiler warnings. (S_exception_raise_request): Pass subcode to inf_debug call. (gnu_write_inferior): Remove unused variable `protection_changed'. (gnu_xfer_memory): Remove unused variable `result'. (set_sig_thread_cmd): Remove unused varible `tid'. (set_signals_cmd): Remve unused variable `trace'. (add_task_commands): Provide complete prototype. Reformat help strings a bit to make sure the first line is a full sentence. Call info_port_rights_cmd instead of info_send_rights_cmd for the "info port-rights" command. (add_thread_commands): Provide complete prototype. Make static. Reformat help strings a bit to make sure the first line is a full sentence. (_initialize_gnu_nat): Provide complete prototype. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2e67f2eb3d3..bc8b82224d5 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,31 @@ +2000-02-26 Mark Kettenis + + * gnu-nat.c: Include "gdbthread.h".
