parseIRError: Raise an error from parseIR

In doktorschiwago/Rllvm2: Interface to llvm for dynamically compiling native code.

Description

This is an R-level function for raising an error specifically from parsing an IR file. This is implemented in R and called from C++ code because the messages were calling problems and also because it is easier to raise richer errors, i.e. with classes and extra information.

Usage

parseIRError(line, col, msg)

Arguments

line	the line number in the file where the error occurred
col	the column number in the line where the error occurred
msg	the message describing the error as provided by LLVM

Value

An error object of class ParseIRError and LLVMError.
