I have a virtual CPU architecture set up that is rather strange. It has similar commands to the x86 architecture, but every registry memory location is 1 'byte' each byte is really a 32 bit floating point number. So if you go mov [345], 1 mov [346], 2e99 this moves the floating point number 1.0 into memory location 345, and floating point number 2e99 into memory location 346, even though these are 32 bit floats and each address is only 1 'byte'. Get it? I was wondering if it would be possible to write a gcc backend for this kind of cpu. I was under the impression that the backend had to have RTLs for at least mov instructions for QImode and SFmode... is it possible to have everything run in a single mode that is floating point? Thanks, Mark
