1 /* mmx.h
3 MultiMedia eXtensions GCC interface library for IA32.
5 To use this library, simply include this header file
6 and compile with GCC. You MUST have inlining enabled
7 in order for mmx_ok() to work; this can be done by
8 simply using -O on the GCC command line.
10 Compiling with -DMMX_TRACE will cause detailed trace
11 output to be sent to stderr for each mmx operation.
12 This adds lots of code, and obviously slows execution to
13 a crawl, but can be very useful for debugging.

20 1997-98 by H. Dietz and R. Fisher
22 History:
23 97-98* R.Fisher Early versions
24 980501 R.Fisher Original Release
25 980611* H.Dietz Rewrite, correctly implementing inlines, and
26 R.Fisher including direct register accesses.
27 980616 R.Fisher Release of 980611 as 980616.
28 980714 R.Fisher Minor corrections to Makefile, etc.
29 980715 R.Fisher mmx_ok() now prevents optimizer from using
30 clobbered values.
31 mmx_ok() now checks if cpuid instruction is
32 available before trying to use it.
33 980726* R.Fisher mm_support() searches for AMD 3DNow, Cyrix
34 Extended MMX, and standard MMX. It returns a
35 value which is positive if any of these are
36 supported, and can be masked with constants to
37 see which. mmx_ok() is now a call to this
38 980726* R.Fisher Added i2r support for shift functions
39 980919 R.Fisher Fixed AMD extended feature recognition bug.
40 980921 R.Fisher Added definition/check for _MMX_H.
41 Added "float s[2]" to mmx_t for use with
42 3DNow and EMMX. So same mmx_t can be used.
43 981013 R.Fisher Fixed cpuid function 1 bug (looked at wrong reg)
44 Fixed psllq_i2r error in mmxtest.c
46 * Unreleased (internal or interim) versions
48 Notes:
49 It appears that the latest gas has the pand problem fixed, therefore
50 I'll undefine BROKEN_PAND by default.
51 String compares may be quicker than the multiple test/jumps in vendor
52 test sequence in mmx_ok(), but I'm not concerned with that right now.
54 Acknowledgments:
55 Jussi Laako for pointing out the errors ultimately found to be
56 connected to the failure to notify the optimizer of clobbered values.
57 Roger Hardiman for reminding us that CPUID isn't everywhere, and that
58 someone may actually try to use this on a machine without CPUID.
59 Also for suggesting code for checking this.
60 Robert Dale for pointing out the AMD recognition bug.
61 Jimmy Mayfield and Carl Witty for pointing out the Intel recognition
62 bug.
63 Carl Witty for pointing out the psllq_i2r test bug.
