LLVM.PassManager

Description

A PassManager holds collection of passes, to be run on Modules. Build one with withPassManager:

using CuratedPassSetSpec if you want optimization but not to play with your compiler
using PassSetSpec if you do want to play with your compiler

Synopsis

Documentation

data PassManager Source #

http://llvm.org/doxygen/classllvm_1_1PassManager.html Note: a PassManager does substantive behind-the-scenes work, arranging for the results of various analyses to be available as needed by transform passes, shared as possible.

data PassSetSpec Source #

There are different ways to get a PassManager. This type embodies them.

Constructors

PassSetSpec	a `PassSetSpec` is a lower-level, detailed specification of a set of passes. It allows fine-grained control of what passes are to be run when, and the specification of passes not available through `CuratedPassSetSpec`.
Fields transforms :: [Pass] dataLayout :: Maybe DataLayout targetLibraryInfo :: Maybe TargetLibraryInfo targetMachine :: Maybe TargetMachine
CuratedPassSetSpec	This type is a high-level specification of a set of passes. It uses the same collection of passes chosen by the LLVM team in the command line tool `opt`. The fields of this spec are much like typical compiler command-line flags - e.g. -O<n>, etc.

defaultPassSetSpec :: PassSetSpec Source #

an empty PassSetSpec

defaultCuratedPassSetSpec :: PassSetSpec Source #

Helper to make a curated PassSetSpec

withPassManager :: PassSetSpec -> (PassManager -> IO a) -> IO a Source #

bracket the creation of a PassManager

runPassManager :: PassManager -> Module -> IO Bool Source #

run the passes in a PassManager on a Module, modifying the Module.
