Tyler Stachecki	10d32ce427	Optimize FPU operations somewhat.	2015-01-27 10:27:13 -05:00
Tyler Stachecki	10a5983c0c	Add support for SSE4 FPU acceleration. ... 0d4a5de2f6 is wrong; we can take advantage of SSE4 rounding intrinsics.	2014-11-16 14:06:34 -05:00
Tyler Stachecki	061a04e216	Change width of fpu_state_t for x86_64. ... gcc (and probably other compilers) don't like working with 16-bit types and will zero-extend where needed. Save some overhead and just store the state as a 32-bit type.	2014-11-15 15:44:04 -05:00
Tyler Stachecki	a0f1eb5d7c	Move intrinsics to a common location.	2014-11-09 18:51:54 -05:00
Tyler Stachecki	1513f3cac2	arch/x86_64: Prefer _mm_set_s* over _mm_load_s*.	2014-11-09 18:27:14 -05:00
Tyler Stachecki	38ba3f7893	Fix x86_64 build errors in last commits.	2014-08-21 12:24:08 -04:00
Tyler Stachecki	ced4183158	More restructuring of arch/ and os/ code.	2014-08-18 16:54:01 +00:00
Tyler Stachecki	3e8ba50851	Add common arch/ folder, move headers out of os/. ... Much of the architecture-specific code uses compiler-agnostic intrinsics. For this reason, split it out into an arch/ folder, leaving only the compiler and environment-specific code in os/.	2014-08-18 16:08:45 +00:00
