Re: Question about profiling reports

Hi Celeste, You may already be aware, but there’s an alternative format to visualise profiles graphically. Instead of `-p`, use `-pj` to produce the profiling report in JSON format, and then load the resulting .prof file into speedscope.app <https://www.speedscope.app/>. Cheers, R

Re: CountDeps

Hey Simon CountDepsParser and CountDepsAST list the closure of the Parser/AST modules dependencies respectively. This test helps keep in check our goal of making the AST not depend on GHC.* modules (the overarching goal of #21592). In your case, you’ve extended the closure by adding dependencie

Unfortunately you’re not the only developer facing these build errors. They've been reported in #23810 and #23789 . It might be worth pasting your workaround there too. Thanks, Rodrigo > On 8

Re: Configure errors

The trace is akin to the configure trace — it shows invocations of the toolchain in trying to determine properties of said toolchain e.g. which flags are supported. For example > checking for -Qunused-arguments support... > Entering: checking for -Qunused-arguments support > Execute: /u

Re: Configure errors

Thanks for pointing this out, Simon What you’ve pasted is the trace of the ghc-toolchain program. We should probably lower the verbosity after !10976 lands, but in the meantime it’s just useful to debug mostly CI. At the end of the configure step there might be a message that starts with “Don’t

Why do the reverse binder swap transformation?

Dear GHC devs, I’m wondering about the reverse binder swap transformation, the one in which we substitute occurrences of the case binder by occurrences of the scrutinee (when the scrut. is a variable): case x of z { r -> e } ===> case x of z { r -> e[x/z] } My question

Re: Can't build nofib

From the error message it looks like you’re using ghc-9.6(and base 4.18) while nofib requires base < 4.17. I’d say as a temporary workaround you can likely run your invocation additionally with —allow-newer, and hope that doesn’t break. Otherwise you could downgrade to 9.4 or bump the version ma

The root of the second problem was !10723, which started failing on its own pipeline after being rebased. I’m pushing a fix. - Rodrigo > On 28 Jun 2023, at 06:41, Bryan Richter via ghc-devs > wrote: > > Two things are negatively impacting GHC CI right now: > > Darwin runner capacity is down

Indeed, this is included in the GHC 9.6.x Migration Guide . Unfortunately, I’m also not sure there is a solution for this particular where (T m) is only a Monad if m instances MonadIO. As
