Hi Guille, I don't get something here. If you are using Exupery to generate asm code why are you talking about a C compiler? > I compile the ST code from .st files to .s (assembler) using > SmaCC, RefactoryBrowser, and then exupery, I still need > squeak in order to run all that. > I only use the bottom layer of exupery, (does not use > IntermediateXXXXXX > classes) > I implemented the cmovxx instruction in exupery, because it > is very useful. > But I need jump tables to implement for example, faster > versions of ifTrue:ifFalse:, and a lot of other things.
