Source: stalin
Section: devel
Priority: optional
Maintainer: Rob Browning <rlb@cs.utexas.edu>
Standards-Version: 2.4.1.2
Package: stalin
Architecture: any
Depends: ${shlibs:Depends}, libgc5-dev
Description: An extremely aggressive Scheme compiler.
Stalin is an aggressive self-hosting Scheme compiler. It is designed
to generate extremely efficient stand-alone executables in terms of
both computational performance and resource consumption. Stalin is a
batch mode compiler like gcc, not an interpreter. It is designed to
be used after your code has stabilized to dramatically improve code
performance.
.
In exchange for substantial performance increases, Stalin places a
few limitations on the content of the source code. The chief
limitation is that you may not not LOAD or EVAL new expressions or
procedure definitions within a running program. This restriction
allows Stalin to perform various sophisticated global analyses.
These analyses include soft, static type analysis which allows it,
when appropriate, and without any type declarations in the source, to
map Scheme types directly to native C types, and use native
arithmetic operations on a per expression basis. This analysis also
allows Stalin to reduce, or often eliminate, run-time type checking
and dispatching. Stalin also does careful lifetime analysis for all
allocated data. This allows Stalin to completely eliminate garbage
collection for data with limited scope or accessibility.
.
Stalin also performs a careful reachability analysis to eliminate any
items from the output that are inaccessible.
.
Stalin has a foreign procedure interface to both Xlib and OpenGL.
