SDK v1.2.0

Pessimizations

• Prevent power-of-two memcpy's of more than one byte from being lowered to integer loads and stores. This causes memcpy to be emitted in more places for now, but preserves the fact that the source and destination cannot alias. This will allow a more efficient lowering of these memcpy's in a nearby release.

New target

• #127 -- PC Engine CD-ROM^2 / TurboGrafx-CD (pce-cd) -- @asiekierka

Bug fixes

• #125 -- Corrected X16 imaginary register layout WRT callee/caller saved registers. -- @asiekierka

Optimizations

• Enable alias analysis in machine scheduler, which allows loads and stores that cannot alias to move past each other to reduce register pressure.

Libraries

• #128 -- Various additions to libc -- @asiekierka
