-Subject: [PATCH] gdb: Fix ia64 defining TRAP_HWBKPT before including
- gdb_wait.h
-
-On ia64, gdb_wait.h eventually includes siginfo-consts-arch.h, which
-contains an enum with TRAP_HWBKPT, along with a #define. Thus we cannot
-define TRAP_HWBKPT to 4 beforehand, and so gdb_wait.h must be included
-earlier; include it from linux-ptrace.h so it can never come afterwards.
-
-gdb/ChangeLog:
-
- * nat/linux-ptrace.c: Remove unnecessary reinclusion of
- gdb_ptrace.h, and move including gdb_wait.h ...
- * nat/linux-ptrace.h: ... to here.
