I noticed in the GCC 3.4 release notes that gcc now support the MaverickCrunch engine on the Cirrus Logic EP93XX ARM920T devices. It also says that multilib support can be enabled for this part by editing "gcc/config/arm/t-arm-elf". However, I understand that crosstool disables multilib so if I want to use the MaverickCrunch support in libgcc then I need to build a new crosstool target. I decided to use demo-arm9tdmi.sh and arm9tdmi.dat as a starting point for the EP9312 build so I copied them to demo-arm-ep9312.sh and arm-ep9312.dat. (I've attached the patch) The toolchain compiled, and it appears to be building code with crunch instructions; could somebody please take a look at what I've done and let me know if I'm doing things right? Thanks, g.
