GHC.Platform

Description

A description of the platform we're compiling for.

Synopsis

Documentation

data PlatformMini Source #

Contains the bare-bones arch and os information. This isn't enough for code gen, but useful for tasks where we can fall back upon the host platform, as this is all we know about the host platform.

data Platform Source #

Contains enough information for the native code generator to emit code for this platform.

platformArch :: Platform -> Arch Source #

Legacy accessor

Legacy accessor

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.

data OS Source #

Operating systems that the native code generator knows about. Having OSUnknown should produce a sensible default, but no promises.

target32Bit :: Platform -> Bool Source #

This predicate tells us whether the platform is 32-bit.

osElfTarget :: OS -> Bool Source #

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

osMachOTarget :: OS -> Bool Source #

This predicate tells us whether the OS support Mach-O shared libraries.

data PlatformMisc Source #

Platform-specific settings formerly hard-coded in Config.hs.

These should probably be all be triaged whether they can be computed from other settings or belong in another another place (like Platform above).
