# The DSP filters spend a lot of time spinning around in little
# loops multiplying and adding arrays of numbers.  The Intel "SSE"
# instructions, introduced in 1999 with the Pentium III series,
# can speed this up considerably.
#
# SSE2 instructions, added in 2000, don't seem to offer any advantage.
#
#
# Let's take a look at the effect of the compile options.
#
#
# Times are elapsed time to process Track 2 of the TNC test CD.
#
# i.e.   "./atest 02_Track_2.wav"
# Default demodulator type is new "E" added for version 1.2.

# gcc 4.6.3 running on Ubuntu 12.04.05.
# Intel(R) Celeron(R) CPU 2.53GHz.  Appears to have only 32 bit instructions.
# Probably from around 2004 or 2005.
#
# When gcc is generating code for a 32 bit x86 target, it assumes the ancient 
# i386 processor.  This is good for portability but bad for performance.
#
# The code can run considerably faster by taking advantage of the SSE instructions 
# available in the Pentium 3 or later.

#	2. Some older versions of gcc don't recognize "native" as a valid choice.
#	3. Results are less portable.  Not a consideration if you are 
#		building only for your own use but very important for anyone
#		redistributing a "binary" version.
#
# If you are planning to distribute the binary version to other 
# people (in some ham radio software collection, RPM, or DEB package), 
# avoid fine tuning it for your particular computer.  It could
