Compilation of Floating Point Arithmetic
in the High Performance Erlang Compiler
ASTEC Master Thesis Presentation
(performed in the context of the HiPE project)
In the context of the dynamically typed concurrent functional
programming language Erlang, we describe a simple static analysis
for identifying variables containing floating point numbers, how
this information is used by the BEAM compiler, and a scheme for
efficient compilation of floating point bytecode instructions
to native code.
The attractiveness of the scheme lies in its implementation
simplicity. It has been fully incorporated in Erlang/OTP R9,
and improves the performance of Erlang programs manipulating
floats considerably. We also show that by using this scheme,
Erlang/OTP, despite being an implementation of a dynamically
typed language, achieves performance which is competitive with
that of state-of-the-art implementations of strongly typed
strict functional languages (e.g. SML/NJ) on floating point
