GHC.Platform

Platform description

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

Platform architecture

Platform OS

Platform architecture and OS.

Architectures

Operating systems.

Using OSUnknown to generate code should produce a sensible default, but no promises.

ARM Instruction Set Architecture

ARM extensions

ARM ABI

PowerPC 64-bit ABI

Byte ordering.

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

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

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

Minimum representable Int value for the given platform

Maximum representable Int value for the given platform

Maximum representable Word value for the given platform

Test if the given Integer is representable with a platform Int

Test if the given Integer is representable with a platform Word

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.

Does this platform have an RTS linker?

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).

x86 SSE and AVX instructions

x86 BMI (bit manipulation) instructions

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