Function

From Rllvm v0.7-0 by Duncan Lang

Create an LLVM function/routine

This function and class creates a template Function object which we can use to build a native, compiled function.

This is not to be confused with the R reserved word function.

Keywords: programming

Usage

Function(name, retType, paramTypes = list(), module = Module(), varArgs = FALSE, ...)

Arguments

name: a string giving the name of the function
retType: the return type of the new function. This should be of class Type-class.
paramTypes: a list giving the types of the parameters of the function. These can be named or not.
module: the module in which the function is to be defined
varArgs: a logical value that indicates whether the routine has variadic arguments, i.e. passed to it via … (not the … in this function)
…: additional inputs for this call (not for calling the routine)

Value

An object of class Function

Examples

# NOT RUN {

# This shows how we can use LLVM to call an existing routine.
m = Module()
ee = ExecutionEngine(m)
Rf_PrintValue = declareFunction(list(VoidType, SEXPType),  "Rf_PrintValue", m)
llvmAddSymbol("Rf_PrintValue")
.llvm(Rf_PrintValue, 1:10)
# }
