#8276: Building Haddock documentation panics with perf build on x86_64 Linux ---------------------------------------+---------------------------------- Reporter: jstolarek | Owner: thoughtpolice Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: Documentation | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 (amd64) Type of failure: Compile-time crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ---------------------------------------+---------------------------------- Comment (by thoughtpolice): hrrrrrrrrrrrrrgh. OK, so this patch mostly works but there's a problem; several libraries use `-fcpr-off` which is a !StaticFlag, meaning when it's passed to Haddock things mess up. Thinking about it, there are two other cases this could happen: * `-fno-state-hack` * `-fno-opt-coercion` To change this !StaticFlag would literally upset hundreds upon hundreds of call sites, and require substantial refactoring as it would introduce boot files and recursive dependencies across the frontend. Basically, the same thing I mentioned before. SimonH, me and Edsko are also a bit confused on how this randomly popped up out of nowhere as well. Perhaps Christiaan's patch is the way to go, but I don't like keeping code like this around since it seems broke. I'm not sure we have much of an option, however, until I get around to removing the remaining !StaticFlags. Which will take a while. Alternatively, we can still remove all this code, and simply special-case Haddock and !DocTest to totally ignore these flags and just not pass them to GHC. While they ''do'' affect how the optimizers work, I'm do not believe this could affect either Haddock or !DocTest in most situations.
