#11158: Combine exprIsTrivial and cpe_ExprIsTrivial -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Look at `CoreUtils.exprIsTrivial` and `CorePrep.cpe_ExprIsTrivial`. They are identical! The latter has a comment saying {{{ cpe_ExprIsTrivial :: CoreExpr -> Bool -- Version that doesn't consider an scc annotation to be trivial. }}} but the code does not treat ticks any differently. So the question is: '''are they supposed to be different'''? And if not, can we just combine them? Peter W, Simon M: this is your territory. I don't understand tick stuff well enough.
