/*	mmx.h

	MultiMedia eXtensions 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 mmx_ok() to work; this can be done by
	simply using -O on the GCC command line.

	Compiling with -DMMX_TRACE will cause detailed trace
	output to be sent to stderr for each mmx 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.

	1997-98 by H. Dietz and R. Fisher

 History:
	97-98*	R.Fisher	Early versions
	980501	R.Fisher	Original Release
	980611*	H.Dietz		Rewrite, correctly implementing inlines, and
		R.Fisher	 including direct register accesses.
	980616	R.Fisher	Release of 980611 as 980616.
	980714	R.Fisher	Minor corrections to Makefile, etc.
	980715	R.Fisher	mmx_ok() now prevents optimizer from using
				 clobbered values.
				mmx_ok() now checks if cpuid instruction is
				 available before trying to use it.
	980726*	R.Fisher	mm_support() searches for AMD 3DNow, Cyrix
				 Extended MMX, and standard MMX.  It returns a
				 value which is positive if any of these are
				 supported, and can be masked with constants to
				 see which.  mmx_ok() is now a call to this
	980726*	R.Fisher	Added i2r support for shift functions
	980919	R.Fisher	Fixed AMD extended feature recognition bug.
	980921	R.Fisher	Added definition/check for _MMX_H.
				Added "float s[2]" to mmx_t for use with
				  3DNow and EMMX.  So same mmx_t can be used.
	981013	R.Fisher	Fixed cpuid function 1 bug (looked at wrong reg)
				Fixed psllq_i2r error in mmxtest.c

	* Unreleased (internal or interim) versions

 Notes:
	It appears that the latest gas has the pand problem fixed, therefore
	  I'll undefine BROKEN_PAND by default.
	String compares may be quicker than the multiple test/jumps in vendor
	  test sequence in mmx_ok(), but I'm not concerned with that right now.

 Acknowledgments:
	Jussi Laako for pointing out the errors ultimately found to be
	  connected to the failure to notify the optimizer of clobbered values.
	Roger Hardiman for reminding us that CPUID isn't everywhere, and that
	  someone may actually try to use this on a machine without CPUID.
	  Also for suggesting code for checking this.
	Robert Dale for pointing out the AMD recognition bug.
	Jimmy Mayfield and Carl Witty for pointing out the Intel recognition
	  bug.
	Carl Witty for pointing out the psllq_i2r test bug.
