From 93282e61398111d4b5da995f46cf5493dba47153 Mon Sep 17 00:00:00 2001 From: "K. Richard Pixley" Date: Thu, 1 Oct 1992 22:44:25 +0000 Subject: [PATCH] Sun3 native support. * config/sun3os3.mh, config/sun3os4.mh (NAT_FILE, NATDEPFILES): new macros for native support. (XDEPFILES): moved infptrace.o and inftarg.o to NATDEPFILES, removed sun3-xdep.o. * xm-sun3.h (ATTACH_DETACH, FETCH_INFERIOR_REGISTERS): moved to nm-sun3.h. * sun3-xdep.c: removed. All code is now in sun3-nat.c. * sun3-nat.c, nm-sun3.h: new files for native support. --- gdb/ChangeLog | 23 +++++++ gdb/config/sun3os3.mh | 4 +- gdb/config/sun3os4.mh | 4 +- gdb/nm-sun3.h | 26 ++++++++ gdb/sun3-nat.c | 138 ++++++++++++++++++++++++++++++++++++++++++ gdb/xm-sun3.h | 8 --- 6 files changed, 193 insertions(+), 10 deletions(-) create mode 100644 gdb/nm-sun3.h create mode 100644 gdb/sun3-nat.c diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2e64487b874..f4bb1740a0f 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,26 @@ +Thu Oct 1 14:36:42 1992 K.
