David Given 7aa60a6451 Register spilling to the stack frame works, more or less. 2016-10-15 22:53:56 +02:00
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 517120d0fb Allow asm names for registers which are different from the friendly names shown
in the tracing (because PowerPC register names are just numbers).

David Given f06b51c981 Keep track of register types as well as attributes --- the type being how we
find new registers when evicting values. Input constraints work (they were
being ignored before). Various bug fixing so they actually work.

David Given fac12aae32 Calculate phi congruency groups; use them to solve the
importing-hreg-from-the-future problem (probably poorly).

David Given d75cc0a663 Basic register allocation works! 2016-10-08 23:32:54 +02:00
David Given 4e49830e09 Overhaul of everything phi related; critical edge splitting now happens before
anything SSA happens; liveness calculations now look like they might be
working.

David Given 92502901a7 Better management of register data. Add struct hreg. 2016-10-05 21:00:28 +02:00
