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.
