mcg now uses dataf4 and dataf8 to emit floating point constants, and so doesn't
...
need flt_arith any more. (And also generates them correctly on little-endian
systems.) as now parses numbers properly, doesn't trash memory all over the
place, and can handle negative numbers.

Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating
...
*some* code.

Function termination gets routed through an exit block; we now have prologues
...
and epilogues. mcgg now exports some useful data as headers. Start factoring
out some of the architecture-specific bits into an architecture-specific file.

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.

IR codes are now owned by mcgg; ir terminals are inserted into the table during
...
compilation (so you can refer to them).

Crudely bolt on mcgg to mcg itself.

Tracing cleanup. Simplified the IR code. Some more opcodes.

Massive grammar overhaul and refactor. Hacked in support for predicates, where
...
instructions can be turned on and off based on their parameters. New lexer
using a lexer. Now quite a lot of the way towards being a real instruction
selector.

Store the EM code up front and build the basic block graph *before*
...
generating the IR code. Lots more IR code.
