Platforms

The following table describes to what extent GHC currently supports various platforms. To find out who is responsible for each platform, see Contributors.

Definitions:

Reg'd (Registerised)

A catch-all term for a number of optimisations, which collectively require the mangler (a Perl script that post-processes the assembly output from gcc). Unregisterised builds require only a working C compiler and are hence far more portable. The registerised optimisations include: direct tail calls (as opposed to using the "mini-interpreter"), info-tables adjacent to entry code, and virtual machine registers mapped to real machine registers.

GHCi

The interactive environment, including dynamic linking of object code and dynamic generation of FFI calls.

NCG

Native code generator: GHC can generate assembly code directly for this platform, bypassing gcc.

f.i. wrapper

Support for foreign import "wrapper" (ghc/rts/Adjustor.c).

Dynamic libraries

Support for generating dynamically-linked sharable libraries from Haskell code.
