Platform description

This is used to describe platforms so that we can generate code for them.

Constructors

Platform
- platformArchOS :: !ArchOS
  Architecture and OS
- platformWordSize :: !PlatformWordSize
  Word size
- platformByteOrder :: !ByteOrder
  Byte order (endianness)
- platformUnregisterised :: !Bool
- platformHasGnuNonexecStack :: !Bool
- platformHasIdentDirective :: !Bool
- platformHasSubsectionsViaSymbols :: !Bool
  Enable Darwin .subsections_via_symbols directive
  See Note [Subsections Via Symbols] in GHC.CmmToAsm.X86.Ppr
- platformIsCrossCompiling :: !Bool
- platformLeadingUnderscore :: !Bool
  Symbols need underscore prefix
- platformTablesNextToCode :: !Bool
  Determines whether we will be compiling info tables that reside just before the entry code, or with an indirection to the entry code. See TABLES_NEXT_TO_CODE in rtsincludertsstorageInfoTables.h.
- platformHasLibm :: !Bool
  Some platforms require that we explicitly link against libm if any math-y things are used (which we assume to include all programs). See #14022.
- platform_constants :: !Maybe PlatformConstants
  Constants such as structure offsets, type sizes, etc.

valuetarget32Bit :: Platform -> Bool

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

valueosElfTarget :: OS -> Bool

This predicate tells us whether the OS uses the ELF as its primary object format.

valueosMachOTarget :: OS -> Bool

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

Test if the given Integer is representable with a platform Int

valueplatformInWordRange :: Platform -> Integer -> Bool

Test if the given Integer is representable with a platform Word

valueplatformCConvNeedsExtension :: Platform -> Bool

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.

valueplatformHasRTSLinker :: Platform -> Bool

Does this platform have an RTS linker?

datadata PlatformMisc

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).
