...d to think they would belong to the same loop pass manager. But it does not seem to be the case. For example for this code snippet PM.add(createIndVarSimplifyPass()); // Canonicalize indvars MPM.add(createLoopIdiomPass()); // Recognize idioms like memset. addExtensionsToPM(EP_LateLoopOptimizations, MPM); MPM.add(createLoopDeletionPass()); // Delete dead loops .. if (!DisableUnrollLoops) MPM.add(createSimpleLoopUnrollPass(OptLevel)); // Unroll small loops I see -debug-pass=Structure output: Scalar Evolution Analysis Loop Pass Manager Induction Va...
