./math/djbfft, Extremely fast library for floating-point convolution

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 0.76, Package name: djbfft-0.76, Maintainer: schmonz

djbfft is an extremely fast library for floating-point convolution.
The current version holds most of the speed records for double-precision
FFTs on general-purpose computers.

djbfft provides power-of-2 complex FFTs, real FFTs at twice the
speed, and fast multiplication of complex arrays. Single precision
and double precision are equally supported.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
