In duncantl/Rllvm: Interface to llvm for dynamically compiling native code.

Get Information about the Host Machine/Architecture

Description

These functions provide information about the machine/architecture and also the data layout for this architecture.

Usage

getHostCPUName()
getHostCPUFeatures()
getDataLayoutString()
isLittleEndian(datalayout)
getABITypeAlignment(datalayout, type)

Arguments

datalayout	a DataLayout instance
type	a Type object

Value

getHostCPUName returns a character string.
