+ // Overview:
+ // The Pass Manager Infrastructure manages passes. It's responsibilities are:
+ //
+ // o Manage optimization pass execution order
+ // o Make required Analysis information available before pass P is run
+ // o Release memory occupied by dead passes
+ // o If Analysis information is dirtied by a pass then regenerate Analysis
+ // information before it is consumed by another pass.
+ //
+ // Pass Manager Infrastructure uses multiple pass managers. They are
+ // PassManager, FunctionPassManager, MPPassManager, FPPassManager,
BBPassManager.
+ // This class hierarcy uses multiple inheritance but pass managers do not
derive
+ // from another pass manager.
+ //
+ // PassManager and FunctionPassManager are two top-level pass manager that
+ // represents the external interface of this entire pass manager
infrastucture.
+ //
+ // Important classes :
+ //
+ // [o] class PMTopLevelManager;
+ //
+ // Two top level managers, PassManager and FunctionPassManager, derive from
+ // PMTopLevelManager. PMTopLevelManager manages information used by top level
+ // managers such as last user info.
+ //
+ // [o] class PMDataManager;
+ //
+ // PMDataManager manages information, e.g. list of available analysis info,
+ // used by a pass manager to manage execution order of passes. It also
provides
+ // a place to implement common pass manager APIs. All pass managers derive
from
+ // PMDataManager.
+ //
+ // [o] class BBPassManager : public FunctionPass, public PMDataManager;
+ //
+ // BBPassManager manages BasicBlockPasses.
+ //
+ // [o] class FunctionPassManager;
+ //
+ // This is a external interface used by JIT to manage FunctionPasses. This
+ // interface relies on FunctionPassManagerImpl to do all the tasks.
+ //
+ // [o] class FunctionPassManagerImpl : public ModulePass, PMDataManager,
+ // public PMTopLevelManager;
+ //
+ // FunctionPassManagerImpl is a top level manager. It manages FPPassManagers
+ //
+ // [o] class FPPassManager : public ModulePass, public PMDataManager;
+ //
+ // FPPassManager manages FunctionPasses and BBPassManagers
+ //
+ // [o] class MPPassManager : public Pass, public PMDataManager;
+ //
+ // MPPassManager manages ModulePasses and FPPassManagers
+ //
+ // [o] class PassManager;
+ //
+ // This is a external interface used by various tools to manages passes. It
+ // relies on PassManagerImpl to do all the tasks.

[llvm-commits] CVS: llvm/include/llvm/PassManagers.h
Changes in directory llvm/include/llvm:
PassManagers.h updated: 1.17 -> 1.18
---
Log message:
Use 'static const char' instead of 'static const int'.
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.
