add methods - These methods are used to add different types of instructions to the alias sets. Adding a new instruction can result in one of three actions happening: 1. If the instruction doesn't alias any other sets, create a new set. 2. If the instruction aliases exactly one set, add it to the set 3. If the instruction aliases multiple sets, merge the sets, and add the instruction to the result. These methods return true if inserting the instruction resulted in the addition of a new alias set (i.e., the pointer did not alias anything).

|
containsPointer - Return true if the specified location is represented by this alias set, false otherwise. This does not modify the AST object or alias sets. Definition at line 209 of file AliasSetTracker.cpp. |
|
copyValue - This method should be used whenever a preexisting value in the program is copied or cloned, introducing a new value. Note that it is ok for clients that use this method to introduce the same value multiple times: if the tracker already knows about a value, it will ignore the request. Definition at line 453 of file AliasSetTracker.cpp. References llvm::AliasSet::addPointer(), llvm::AliasAnalysis::copyValue(), and I. |
|
deleteValue method - This method is used to remove a pointer value from the AliasSetTracker entirely. It should be used when an instruction is deleted from the program to update the AST. If you don't use this, you would have dangling pointers to deleted instructions.

|
getAliasAnalysis - Return the underlying alias analysis object used by this tracker. Definition at line 317 of file AliasSetTracker.h. Referenced by llvm::AliasSet::mergeSetIn(). |
|
getAliasSetForPointer - Return the alias set that the specified pointer lives in. If the New argument is non-null, this method sets the value to true if a new alias set is created to contain the pointer (because the pointer didn't alias anything). Definition at line 237 of file AliasSetTracker.cpp. References llvm::AliasSet::addPointer(), and AliasSet. |
|
getAliasSetForPointerIfExists - Return the alias set containing the location specified if one exists, otherwise return null. Definition at line 306 of file AliasSetTracker.h. |
|
getAliasSets - Return the alias sets that are active. Definition at line 296 of file AliasSetTracker.h. |

remove methods - These methods are used to remove all entries that might be aliased by the specified instruction. These methods return true if any alias sets were eliminated. Definition at line 369 of file AliasSetTracker.cpp. Referenced by remove(). |
