The +compiler is the interpreter extended with the capability of generating +executable files. The compiler can produce standalone executables or compiled +modules which can be loaded at run time. Interpreted code and compiled code +can be freely mixed. + +Gambit-C is a version of the Gambit programming system in which the compiler +generates portable C code. The main features of Gambit-C are: + + * Conformance: The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme + standards and implements all optional features. Tail calls and first class + continuations conform to the Scheme semantics. The full numeric tower is + implemented, including: arbitrary precision integers (bignums), rationals, + inexact reals (floating point numbers), and complex numbers. Several + extensions to Scheme are provided, including: lightweight threads, a + foreign-function interface (FFI), and extended I/O capabilities (Unicode, + networking, subprocesses, ...). + + * Portability: Because the system is mostly written in Scheme and the compiler + generates portable C code, it is easy to port the system as well as programs + compiled with it to any platform with a decent C or C++ compiler. There + is no reliance on a particular C compiler, although the system can + take advantage of some gcc-specific constructs. The C code generated + is oblivious to the endianness and word size of the target environment + (32 and 64 bit architectures are currently supported). + + * Performance: The compiler includes several powerful program transformations + such as user procedure inlining, partial-evaluation, and + lambda-lifting. With appropriate declarations in the source code the + executable programs generated by the compiler run roughly as fast as + equivalent C programs. Programs containing no declarations are also + optimized without compromising the Scheme semantics by speculatively + inlining predefined procedures (see the benchmarks page for a comparison + with other Scheme implementations and other languages). Thanks to an + efficient implementation of continuations, the thread system is very + efficient and can support millions of concurrent threads. + + * Reliability: Stable releases typically have very few bugs. Bug tracking is + done with bugzilla. Gambit-C has been used to develop large-scale real-world + software and services in academic and commercial settings. +EOF |
