David Given 3a973a19f3 Move fatal(), warning() and aprintf() into the new data module (because they're
really useful).

David Given e77c5164cf Fleshed out hops and vregs. The result is almost looking like code now ---
uncanny.

David Given 629e0ddfc6 Some instruction selection is now happening. 2016-09-24 22:46:08 +02:00
David Given bb9aa030a5 Procedure compilation now happens after the entire EM file has been read in (so
that we can look inside data blocks which might be defined in the future...
sigh, csa and csb). csa and csb no longer generate invalid IR.

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.

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.

David Given 6a74cb2e11 Tracing cleanup. Simplified the IR code. Some more opcodes. 2016-09-22 00:15:48 +02:00
