I would like to add 3D now support for my program. I don't think either gcc or
pgcc supports it, but I've heard gas does. Does anyone have a link to some docs
about how to use them with gas. Also, where can I find some doc about these
instructions (except from the non-free doc from AMD)?
Thanks,
Jean-Marc

Maybe you can also find the necessery info in the AMD website.

there was an article in Linux Journal sometime last year about using AMD's
3DNow instructions to implement screaming-fast floating point arithmetic.
Perhaps a visit to the LJ web site would help?

2.6 Does PGCC support MMX or 3Dnow! instructions?
PGCC does support MMX and 3Dnow! - recent snapshots can generate MMX
instructions, and you can include them both in inline assembly. Using inline
assembler will almost certainly produce the best results. To use these
instructions, you need to be using GNU binutils-2.9.1 or later. For full
details, see the optimization section.
To get the 3Dnow! instructions you need to use the -mk6 switch.

1. 3D shutter glasses and X windows (3D-MAX)
I am seriously contemplating trying to get a stereoscopic display
working with LINUX and X-Windows and 3D-MAX LCD shutter glasses. Has
anyone experimented with getting something like this to work? If
anyone has information about someone who is working with hardware
stereo and LINUX, please send me information so that I may learn what
I can.
Short of that, I am looking for answers to the following questions, related
to hardware stereo under LINUX/X.
1) Is it possible to "trick" X into an interlaced mode, with its graphics
memory actually appropriate for a non-interlaced mode? That is, can I
force it into an interlaced mode in which what should be on the top half
of the screen is on the odd numbered scan lines, while what should be on
the bottom half of the screen is on the even numbered scan lines? I
suspect that this would be the best compromise approach to using hardware
stereo while still being able to exploit accelerated graphics operations.
2) What video cards support 120 Hz interlaced modes?
3) What monitors support 120 Hz interlaced modes?
Thank you in advance for any help that you may provide.
