David Given	ed67d427c9	Replaced the block splicer with a trivial block eliminator (which rewrites ... jumps to blocks which contain only a jump). Don't bother storing the bb graph in the ir nodes; we can find it on demand by walking the tree instead --- slower, but much easier to understand and more robust. Added a terrible map library.	2016-09-23 23:59:15 +02:00
David Given	f8bbf9e87d	Each pass now lives in its own source file; much cleaner.	2016-09-23 21:07:16 +02:00
David Given	9077baa850	Add a bodged in algorithm for converting basic block communication from stacked ... variables to SSA. Also add dead block removal and block splicing. IR code is much better now.	2016-09-22 23:19:29 +02:00
David Given	6a74cb2e11	Tracing cleanup. Simplified the IR code. Some more opcodes.	2016-09-22 00:15:48 +02:00
