Oh --- I hadn't thought about that. We should probably set a
breakpoint in main and continue, rather than finishing.

Subject: support for ARM GNU/Linux
Date: Mon, 12 Apr 1999 13:01:00 -0000
Message-id: <E10WmL7-0006R7-00@kings-cross.london.uk.eu.org>
X-SW-Source: 1999-04/msg00011.html
Content-length: 19269
This patch adds support for GNU/Linux running on ARM systems.
p.
1999-04-12 Philip Blundell <philb@gnu.org>
Scott Bambrough <scottb@corelcomputer.com>
Support for ARM GNU/Linux:
* configure.tgt: Recognize arm*-*-linux* configuration. Set
cpu name to `arm' for any `arm*-*-*' configuration name.
* configure.host: Likewise.
* config/arm/linux.mh, config/arm/linux.mt: New files.
* config/arm/tm-linux.h, config-arm/xm-linux.h,
config/arm/nm-linux.h: Likewise.
* armlnx-tdep.c, armlnx-xdep.c, armlnx-nat.c: Likewise.
* arm-tdep.c (ARM_LE_BREAKPOINT, ARM_BE_BREAKPOINT,
THUMB_LE_BREAKPOINT, THUMB_BE_BREAKPOINT, LOWEST_PC,
LITTLE_BREAKPOINT, BIG_BREAKPOINT): Move
definitions to...
* config/arm/tm-arm.h: ... here.
