Hello Mono Community,
We are working on a port of Mono to Tilera's Tile-GX 100-core CPU.

I have a question about the register allocator.  The Tile-GX does not have separate floating point registers - floating point operations use the 55 64-bit general-purpose registers.  As far as I can tell all other Mono architectures have separate floating point registers.

Is the register allocator able to accommodate using general-purpose registers for floating point operations?  Do I simply specify src1:i instead of src1:f in the machine description file?
