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

Maximum representable Int value for the given platform
platformMaxWord :: Platform -> Integer Source #
Maximum representable Word value for the given platform

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.

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).
