Collection of generic functions for LLVM objects

Description

These are some of the generic functions for LLVM

Usage

clone(x, ...)
eraseFromParent(x, delete = TRUE, ...)
getCalledFunction(obj, ...)
getDataLayout(from, asRef = FALSE, ...)
getDescription(x, ...)
getElementTypes(x, ...)
getModule(obj, ...)
getNumElements(x, ...)
getParent(x, ...)
getReturnType(obj, ...)
hasMetadata(x, ...)
hasMetadataOtherThanDebugLoc(x, ...)
isArithmeticShift(x, ...)
isAssociative(x, ...)
isBinaryOp(x, ...)
isCommutative(x, ...)
isLogicalShift(x, ...)
isSafeToSpeculativelyExecute(x, ...)
isShift(x, ...)
isTerminator(x, ...)
mayHaveSideEffects(x, ...)
mayReadFromMemory(x, ...)
mayThrow(x, ...)
mayWriteToMemory(x, ...)
setDataLayout(x, value, ...)

Arguments

x, obj	the object to be queried or whose data layout is to be set. Currently, there are only methods forsetDataLayout for a Module
...	additional arguments for methods
delete	a logical value indicating whether to not only remove from the parent but also destroy the object
from	the object whose data layout will be set
value	a character string describing the data layout. See the LLVM documentation for the Module class http://llvm.org/docs/LangRef.html#data-layout.
asRef	scalar logical indicating whether we want a reference to the DataLayout object or just a description of it.

Note

getReturnType identifies the type of the return value in the Function definition/declaration. However, it may not correspond to what you might expect. LLVM may adapat a C/C++ routine that returns a structure or a C++ object directly (not by reference) to instead return void and add the address of such an object as the first parameter. This will have the sret attribute set on the corresponding parameter. See hasStructRet.
