Detailed Description

Represent the analysis usage information of a pass.

This tracks analyses that the pass REQUIRES (must be available when the pass runs), REQUIRES TRANSITIVE (must be available throughout the lifetime of the pass), and analyses that the pass PRESERVES (the pass does not invalidate the results of these analyses). This information is provided by a pass to the Pass infrastructure through the getAnalysisUsage virtual function.

◆ addPreserved() [2/2]

AnalysisUsage & AnalysisUsage::addPreserved ( StringRef  Arg)

Add the Pass with the specified argument string to the set of analyses preserved by this pass.

If no such Pass exists, do nothing. This can be useful when a pass is trivially preserved, but may not be linked in. Be careful about spelling!

◆ setPreservesCFG()

void AnalysisUsage::setPreservesCFG ( )

This function should be called by the pass, iff they do not:

  1. Add or remove basic blocks from the function
  2. Modify terminator instructions in any way.

This function annotates the AnalysisUsage info object to say that analyses that only depend on the CFG are preserved by this pass.
