Subject: sim/arm/armos.c: IsTTY [PATCH]
Date: Mon, 15 Aug 2005 21:19:00 -0000 [thread overview]
Message-ID: <7f45d9390508151204ca0b146@mail.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 3863 bytes --]
This patch adds support for the ARM IsTTY, Remove, and Rename SWI calls.
Please cc me in your reply. Cheers,
Shaun
2005-08-15 Shaun Jackman <sjackman@gmail.com>
* sim/arm/armos.c (unlink): Remove this macro. It is unused
in this file and conflicts with sim_callback->unlink.
(SWIremove): New function.
(SWIrename): Ditto.
(ARMul_OSHandleSWI): Handle the RDP calls SWI_IsTTY,
SWI_Remove, and SWI_Rename, as well as the RDI calls
AngelSWI_Reason_IsTTY, AngelSWI_Reason_Remove, and
AngelSWI_Reason_Rename.
