Summary: Eliminate the Annotable and Annotation classes by making
MachineFunction a pass
Product: libraries
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Core LLVM classes
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
The only use of the Annotable and Annotation classes are for putting a
MachineFunction on Function. This class is bad for a number of reasons and
should be removed.
The fix is to make MachineFunction be an analysis group that is provided by the
various instruction selectors and required/preserved by MachineFunctionPass.
That way the lifetime of the MachineFunction is managed by PassMgr, not be
explicit code.
