/*	sse.h

	Streaming SIMD Extenstions (a.k.a. Katmai New Instructions)
	GCC interface library for IA32.

	To use this library, simply include this header file
	and compile with GCC.  You MUST have inlining enabled
	in order for sse_ok() to work; this can be done by
	simply using -O on the GCC command line.

	Compiling with -DSSE_TRACE will cause detailed trace
	output to be sent to stderr for each sse operation.
	This adds lots of code, and obviously slows execution to
	a crawl, but can be very useful for debugging.

	THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY
	EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT
	LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY
	AND FITNESS FOR ANY PARTICULAR PURPOSE.

	1999 by R. Fisher
	Based on libmmx by H. Dietz and R. Fisher

 Notes:
	This is still extremely alpha.
	Because this library depends on an assembler which understands the
	 SSE opcodes, you probably won't be able to use this yet.
	For now, do not use TRACE versions.  These both make use
	 of the MMX registers, not the SSE registers.  This will be resolved
	 at a later date.
 ToDo:
	Rewrite TRACE macros
	Major Debugging Work
