Streaming SIMD Extensions (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.
|
|
|

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
