#9630: compile-time performance regression (probably due to Generics) -------------------------------------+------------------------------------- Reporter: hvr | Owner: simonpj Type: bug | Status: new Priority: high | Milestone: 7.10.1 Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Compile- | Blocked By: time performance bug | Related Tickets: #9583 Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): Might it be worth leaving a few comments in the `GBInary` class to highlight that innocently inlining those methods is dangerous? And we still don't really understand why, I think. `gget` looks as if it has lots of cpp-generated code, but the others look small. Unless the things they call are in turn INLINE. So, a good fix, but it might be worth more investigation to figure out the best way to solve this in the end. I think Pedro's goal was to eliminate all the intermediate structure.
