Nebuleon Fumika	8956d5cff2	Clean up some backslashes at the end of lines.	2012-12-30 15:30:14 -05:00
Nebuleon Fumika	d1d0c81af8	Rendering optimisations. ... tile.cpp: Optimise the common case of drawing an unclipped but possibly flipped 8x8 tile. Instead of calling WRITE_4PIXELS16 16 times, each performing setup and teardown, move the loop into DrawTile16. tile.h, tile.cpp, gfx.h, gfx.cpp: End the use of global variable GFX.ScreenColors to pass around the current frame's palette. This saves on memory stores/loads.	2012-12-30 00:20:45 -05:00
Nebuleon Fumika	e5a0c9146a	Transform macros into loops to render tiles. ... At -O3 these get unrolled; at -Os they become shorter code, fitting into the cache with other code.	2012-12-28 22:19:23 -05:00
Nebuleon Fumika	6b36e79013	Speed up rendering by an unknown amount. ... gfx.cpp, others: Avoid always checking for Settings.SixteenBit if FOREVER_16_BIT is defined. port.h: Define FOREVER_16_BIT below PIXEL_FORMAT.	2012-12-27 18:02:03 -05:00
Nebuleon Fumika	e708c127fa	Un-inline a bunch of stuff. ... With the MIPS instruction cache, this means that two consecutive SNES CPU instructions using e.g. the same addressing style or the same opcode have a chance that the second one will use the first one's code and that it will be cached.	2012-12-18 22:53:49 -05:00
