David Given 25b6712e63 Rework all the ackbuilder scripts not to use wildcards, because we can't expand
them without luaposix, which isn't available (easily) on OSX or Windows.

David Given 642956fa2f 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.

David Given 5f0164db62 Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating
*some* code.

David Given 9504aec2bd 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.

David Given 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.

David Given 3671892c34 Move the array library into the data module. 2016-09-26 22:24:49 +02:00
David Given 2acc4ed29d IR codes are now owned by mcgg; ir terminals are inserted into the table during
compilation (so you can refer to them).

David Given 1516657907 Crudely bolt on mcgg to mcg itself. 2016-09-24 17:20:40 +02:00
David Given 6a74cb2e11 Tracing cleanup. Simplified the IR code. Some more opcodes. 2016-09-22 00:15:48 +02:00
David Given 4546dd5f22 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.

David Given 6ce2495aeb Store the EM code up front and build the basic block graph *before*
generating the IR code. Lots more IR code.
