//===- llvm/Transforms/CleanupGCCOutput.h - Cleanup GCC Output ---*- C++ -*--=//
|
|
//
|
|
// These passes are used to cleanup the output of GCC. GCC's output is
|
|
// unneccessarily gross for a couple of reasons. This pass does the following
|
|
// things to try to clean it up:
|
|
//
|
|
// * Eliminate names for GCC types that we know can't be needed by the user.
|
|
// * Eliminate names for types that are unused in the entire translation unit
|
|
// * Fix various problems that we might have in PHI nodes and casts
|
|
// * Link uses of 'void %foo(...)' to 'void %foo(sometypes)'
|
|
//
|
|
// Note: This code produces dead declarations, it is a good idea to run DCE
|
|
// after this pass.
