#8832: Constant-folding regression wrt `clearBit (bit 0) 0 ` -------------------------------------+------------------------------------- Reporter: hvr | Owner: thoughtpolice Type: bug | Status: new Priority: high | Milestone: 7.10.1 Component: Compiler | Version: 7.8.1-rc2 Resolution: | Keywords: Differential Revisions: | Operating System: Unknown/Multiple Architecture: | Type of failure: Runtime Unknown/Multiple | performance bug Difficulty: Unknown | Test Case: Blocked By: | simplCore/should_compile/T8832 Related Tickets: | Blocking: -------------------------------------+------------------------------------- Changes (by simonpj): * priority: normal => high Comment: The bug is fixed. The only issue is that the test has some 64-bit stuff in it, and on a 32-bit machine that doesn't constant-fold. Which is probably fine. To close the ticket we just need to make the test depend on whether we are on a 64-bit machine. I don't know how to do that, but it can't be hard. Could someone do it? I'll make it "high" priority to get it some attention, rather than because it's terribly important.
