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.

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).

Fields

lookupPlatformConstants :: [FilePath] -> IO (Maybe PlatformConstants) Source #

Try to locate "DerivedConstants.h" file in the given dirs and to parse the PlatformConstants from it.
