e93c58dc8d Refactored the way hops are rendered; add support for emitting code (although
with no prologue or epilogue yet).

92bd1ac5f4 Register allocator now gets all the way through all of my test file without
crashing (albeit with register moves and swaps stubbed out). Correct code? Who
knows.

4e49830e09 Overhaul of everything phi related; critical edge splitting now happens before
anything SSA happens; liveness calculations now look like they might be
working.

88fb231d6e Better constraint syntax; mcgg now passes register usage information up to mcg;
mcg can track individual hop inputs and outputs (needed for live range
analysis!); the register allocator now puts the basic blocks into the right
order in preparation for live range analysis.

7a6fc7a72b Made sure that all files end in vim magic. 2016-10-05 21:07:29 +02:00

288ee56203 Get quite a long way towards basic output-register equality constraints (needed
to make special nodes like NOP work properly). Realise that the way I'm dealing
with the instruction selector is all wrong; I need to physically copy chunks of
tree to give to burg (so I can terminate them correctly).

91e277e046 Predicates work; we now have prefers and requires clauses. Predicates must be
functions. Not convinced that semantic types are actually working --- there are
still problems with earlier statements leaving things in the wrong registers.

0d246c0d73 Much better handling of fragments (no run-time code needed to distinguish them
from registers) and better handling of individual hops within a paragraph ---
no more ghastly hacks to try and distinguish the input from the output.

4572f1b774 Actually, I don't need vregs: hops work just as well. Particularly if I
restructure things so that I don't need to walk the blasted ir / burg tree
every time I look at an instruction.

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