Brian Chen (Oct 02 2023 at 02:50): Brian Chen (Oct 02 2023 at 02:50):I've been trying to figure out this mysterious issue posted today on Discourse. A user is seeing allocations, yet using @code_* and Cthulhu don't turn up any calls which could be responsible for so many allocations. Using the allocation profiler wasn't much help either: it showed a bunch of allocations seemingly related to tuple indexing and dynamic dispatch (e.g. apply stuff), but I can't tell why those are happening because I can't coax out IR which shows such calls.
Brian Chen (Oct 02 2023 at 02:51):More vexing is that trying to reduce the MWE to use lower-level library functions makes the allocations go away. Normally that would make me suspect something like inlining, but I have no way to test that because again the IR looks fine...
