Randy Heit	db5938d22a	- Added assembly versions of rt_add4cols and rt_addclamp4cols. ... SVN r773 (trunk)	2008-02-28 05:24:06 +00:00
Randy Heit	9cb674c60c	- Added an assembly version of rt_shaded4cols, since that's the main decal ... drawing function. The most improvement came from being able to turn some constant variables into immediate values with self-modifying code, but I also managed to reorder it to make it a little faster. It's about 9% faster than VC++'s code and 19% faster than GCC's code. That's not a huge improvement (for VC++), but at least it's measurable. - Removed the solid fill "optimization" from rt_shaded4cols(), because in my testing, it didn't help any and in fact, hurt just a little bit. - In the name of simplification, all the rt_tlate* drawers were changed to do the translation in one step and the drawing in another. This lets me call the untranslated drawer to do the real drawing instead of mostly duplicating them. Performance wise, there is practically no difference from before.

Randy Heit	e666cde418	- Fixed some more GCC warnings. ... - Updated project files for nasm 2.0, which is now named nasm.exe for the Windows version, rather than nasmw.exe. Also fixed the annoying new warnings it generated. SVN r593 (trunk)	2007-12-11 02:38:38 +00:00
Randy Heit	bac407c543	- Fixed: The SafeDivScales used a signed shift for their if test. This fails ... when a == 0x80000000, because the result of abs will still be negative as long as we use signed math. - Fixed: SafeDivScale31 performed DivScale32 instead. - Fixed: R_DrawSpanP_ASM had a short jump into a different section.

Randy Heit	cf11cbdb30	Directory restructuring to make it easier to version projects that don't build zdoom.exe. ... SVN r4 (trunk)	2006-02-24 04:48:15 +00:00
