Hi! I'm attempting to build a iWMMXt/Linux EABI toolchain using gcc HEAD. I'm
using the target xscale-iwmmxt-linux-gnueabi, I've added support for this
target to binutils and built a cross linker etc.
I've proceeded to add a suitable target in config.gcc which supports EABI,
xscale and Linux basing it on the existing arm/linux target and replacing the
linux-elf.h file with a modified one based on xscale-elf.h which I've called
xscale-linux-elf.h.
I then attempted to build a stage1 compiler with "--with-abi=iwmmxt
--with-cpu=iwmmxt --with-arch=iwmmxt", but as soon as the build tries to run
xgcc I get the error below. It looks like it's getting the types wrong, but
I'm very new to GCC internals and I'm not sure where to look.
