From 8f25caf5ec24695da22026b4de1045b50bbb95c8 Mon Sep 17 00:00:00 2001 From: palves Date: Tue, 16 Oct 2007 18:43:24 +0000 Subject: [PATCH] * config/i386/mingw.mh, config/i386/mingw.mt: New files. * configure.tgt (i[34567]86-*-mingw32*): Set gdb_target = mingw. * win32-nat.c: Only include cygwin.h on Cygwin host. Don't include procfs.h. (cygwin_load_start, cygwin_load_end, cygwin_exceptions): Disable if not building on Cygwin. (win32_make_so, handle_output_debug_string, handle_exception) (do_initial_win32_stuff): Wrap Cygwin specific code in __CYGWIN__. (win32_attach): Only fallback to Cygwin pids if building on Cygwin. (win32_pid_to_exec_file): Disable Cygwin specific code, if not building on Cygwin. (win32_create_inferior): Disable starting the inferior through a shell, environment var processing and tty handling if not building on Cygwin. (cygwin_pid_to_str): Rename to ... (win32_pid_to_str): ... this. (init_win32_ops): Update use of win32_pid_to_str. Disable "shell" and "cygwin-exceptions" commands if not building on Cygwin. --- gdb/ChangeLog | 22 ++++++++++++++++++++ gdb/config/i386/mingw.mh | 4 ++++ gdb/config/i386/mingw.mt | 3 +++ gdb/configure.tgt | 2 +- gdb/win32-nat.c | 52 ++++++++++++++++++++++++++++++++++++++---------- 5 files changed, 71 insertions(+), 12 deletions(-) create mode 100644 gdb/config/i386/mingw.mh create mode 100644 gdb/config/i386/mingw.mt diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 7e778098aa..56ae33464d 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,25 @@ +2007-10-16 Pedro Alves + + * config/i386/mingw.mh, config/i386/mingw.mt: New files. + * configure.tgt (i[34567]86-*-mingw32*): Set gdb_target = mingw. + * win32-nat.c: Only include cygwin.h on Cygwin host.
