From 40e0b27177e747600d3ec186458fe0e482a1cf77 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Mon, 24 Aug 2015 15:40:26 +0100 Subject: [PATCH] Delete the remaining ROM monitor targets Ref: https://sourceware.org/ml/gdb/2015-07/msg00011.html All of these targets use gdb/monitor.c, which has bit rotted years ago (I'd guess around ~6), and nobody seems to have noticed: | target | source | |----------------+----------------------| | target dbug | gdb/dbug-rom.c | | target picobug | gdb/microblaze-rom.c | | target dink32 | gdb/dink32-rom.c | | target m32r | gdb/m32r-rom.c | | target mon2000 | gdb/m32r-rom.c | | target ppcbug | gdb/ppcbug-rom.c | This deletes them, along with finally removing monitor.c. A manual update will be done separately. gdb/ChangeLog: 2015-08-24 Pedro Alves * NEWS: Mention removed support for the various ROM monitors. * Makefile.in (ALL_TARGET_OBS): Remove dbug-rom.o, dink32-rom.o, ppcbug-rom.o, m32r-rom.o, dsrec.o and monitor.o from gdb_target_obs. * configure.tgt (h8300-*-*): Remove monitor.o and m32r-rom.o from gdb_target_obs.
