# By default this script leaves out these machine-dependent optimizations.
# If your machine supports these, feel free to add them to the configure
# options. Note that fftw may refuse to compile by doing so -- watch for
# error messages about the precision not matching. See the link below.
#
# --enable-fma enable optimizations for machines with fused multiply-add
# --enable-k7 enable AMD K7 optimizations, including 3dNow!
# --enable-sse enable SSE optimizations (Pentium III+)
# --enable-sse2 enable SSE2 optimizations (Pentium IV+)
# --enable-altivec enable Altivec optimizations (PowerPC G4+)
# --enable-portable-binary
# disable compiler optimizations that would produce
# unportable binaries
#
# Compiling with the default options creates a double-precision library
# named libfftw3. --enable-float or --enable-single builds a single
# precision library (libfftw3f), and --enable-long-double builds a
# long-double precision library (libfftw3l). This script builds all three
# libraries since they can coexist on the same machine.
#
# You may be able to --enable one of the SIMD options when compiling for
# one precision, but not for another. Check this page for details:
# http://www.fftw.org/fftw3_doc/Installation-on-Unix.html
