NAME
Faster::Maths - make mathematically-intense programs faster
SYNOPSIS
use Faster::Maths;
# and that's it :)
DESCRIPTION
This module installs an optimizer into the perl compiler that looks for
sequences of maths operations that it can make faster.
When this module is lexically in scope, mathematical expressions
composed of the four basic operators (+, -, *, /) operating on lexical
variables and constants will be compiled into a form that is more
efficient at runtime.
TODO
* Recognise more potential arguments - padrange and package variables
at least.
* Recognise more operators - %, unary - and sqrt, possibly other
unary operators like sin.
* Recognise the presence of overloading magic on variables and fall
back to slower-but-correct operation in that case.
* Split the runtime loop into IV/UV/NV cases, further optimise the
accumulator value in each case.
* Store IV/UV constants as values directly in the UNOP_AUX structure
avoiding the need for SV lookup on them.
* Back-compatibility to perls older than 5.22.0 by providing an
UNOP_AUX implementation.
