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.

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.

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 #
platformMinInt :: Platform -> Integer Source #
Minimum representable Int value for the given platform
platformMaxInt :: Platform -> Integer Source #
Maximum representable Int value for the given platform
platformMaxWord :: Platform -> Integer Source #
Maximum representable Word value for the given platform
platformInIntRange :: Platform -> Integer -> Bool Source #
Test if the given Integer is representable with a platform Int
platformInWordRange :: Platform -> Integer -> Bool Source #
Test if the given Integer is representable with a platform Word
platformCConvNeedsExtension :: Platform -> Bool Source #
For some architectures the C calling convention is that any integer shorter than 64 bits is replaced by its 64 bits representation using sign or zero extension.
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).
