Platform description
This is used to describe platforms so that we can generate code for them.
Constructors
PlatformplatformArchOS :: !ArchOSArchitecture and OS
platformWordSize :: !PlatformWordSizeWord size
platformByteOrder :: !ByteOrderByte order (endianness)
platformUnregisterised :: !BoolplatformHasGnuNonexecStack :: !BoolplatformHasIdentDirective :: !BoolplatformHasSubsectionsViaSymbols :: !BoolEnable Darwin .subsections_via_symbols directive
See Note [Subsections Via Symbols] in GHC.CmmToAsm.X86.Ppr
platformIsCrossCompiling :: !BoolplatformLeadingUnderscore :: !BoolSymbols need underscore prefix
platformTablesNextToCode :: !BoolDetermines 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 :: !BoolSome platforms require that we explicitly link against
libmif any math-y things are used (which we assume to include all programs). See #14022.platform_constants :: !Maybe PlatformConstantsConstants such as structure offsets, type sizes, etc.

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).
