Platform

Description

A description of the platform we're compiling for. Used by the native code generator. In the future, this module should be the only one that references the evil #defines for each TARGET_ARCH and TARGET_OS

Synopsis

data Platform = Platform { platformArch :: Arch platformOS :: OS } data Arch = ArchAlpha | ArchX86 | ArchX86_64 | ArchPPC | ArchPPC_64 | ArchSPARC data OS = OSUnknown | OSLinux | OSDarwin | OSSolaris | OSMinGW32 | OSFreeBSD defaultTargetPlatform :: Platform osElfTarget :: OS -> Bool

Documentation

data Platform Source

Contains enough information for the native code generator to emit code for this platform. Constructors Platform platformArch :: Arch platformOS :: OS

data Arch Source

Architectures that the native code generator knows about. TODO: It might be nice to extend these constructors with information about what instruction set extensions an architecture might support. Constructors ArchAlpha ArchX86 ArchX86_64 ArchPPC ArchPPC_64 ArchSPARC Instances Eq Arch Show Arch

data OS Source

Operating systems that the native code generator knows about. Having OSUnknown should produce a sensible default, but no promises. Constructors OSUnknown OSLinux OSDarwin OSSolaris OSMinGW32 OSFreeBSD Instances Eq OS Show OS

defaultTargetPlatform :: Platform Source

This is the target platform as far as the #ifdefs are concerned. These are set in includes/ghcplatform.h by the autoconf scripts

osElfTarget :: OS -> Bool Source

This predicates tells us whether the OS supports ELF-like shared libraries.
