Subject: [PATCH] Support new target S+core 3, a variant of S+core
Date: Tue, 17 Mar 2009 02:17:00 -0000 [thread overview]
Message-ID: <OFF2760387.B9E13E9A-ON4825757C.000A56D3-4825757C.000A9146@sunplusct.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 995 bytes --]
Hello,
The S+core team in our company have ported GDB to S+core 3, a variant
of S+core, now we want to contribute some patch. So here it is (see
attachment).
Please review it, and any suggestions are most welcome.
At now, I'm quite new to GDB, so if you fond something I did wrong,
please point it out.
Thanks for your time,
Don
