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.

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

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.

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

ARM Instruction Set Architecture, Extensions and ABI
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.
osSubsectionsViaSymbols :: OS -> Bool Source #
platformWordSizeInBits :: Platform -> Int Source #
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).
