* Ticky profiling improvements.Matthew Pickering2022-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | This adds a number of changes to ticky-ticky profiling. When an executable is profiled with IPE profiling it's now possible to associate id-related ticky counters to their source location. This works by emitting the info table address as part of the counter which can be looked up in the IPE table. Add a `-ticky-ap-thunk` flag. This flag prevents the use of some standard thunks which are precompiled into the RTS. This means reduced cache locality and increased code size. But it allows better attribution of execution cost to specific source locations instead of simple attributing it to the standard thunk. ticky-ticky now uses the `arg` field to emit additional information about counters in json format. When ticky-ticky is used in combination with the eventlog eventlog2html can be used to generate a html table from the eventlog similar to the old text output for ticky-ticky.
* Remove transitive information about modules and packages from interface filesMatthew Pickering2021-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit modifies interface files so that *only* direct information about modules and packages is stored in the interface file. * Only direct module and direct package dependencies are stored in the interface files. * Trusted packages are now stored separately as they need to be checked transitively. * hs-boot files below the compiled module in the home module are stored so that eps_is_boot can be calculated in one-shot mode without loading all interface files in the home package. * The transitive closure of signatures is stored separately This is important for two reasons * Less recompilation is needed, as motivated by #16885, a lot of redundant compilation was triggered when adding new imports deep in the module tree as all the parent interface files had to be redundantly updated. * Checking an interface file is cheaper because you don't have to perform a transitive traversal to check the dependencies are up-to-date. In the code, places where we would have used the transitive closure, we instead compute the necessary transitive closure. The closure is not computed very often, was already happening in checkDependencies, and was already happening in getLinkDeps.

* Add `MessageClass`, rework `Severity` and add `DiagnosticReason`.wip/adinapoli-message-class-new-designAlfredo Di Napoli2021-03-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Other than that: * Fix T16167,json,json2,T7478,T10637 tests to reflect the introduction of the `MessageClass` type * Remove `makeIntoWarning` * Remove `warningsToMessages` * Refactor GHC.Tc.Errors 1. Refactors GHC.Tc.Errors so that we use `DiagnosticReason` for "choices" (defer types errors, holes, etc); 2. We get rid of `reportWarning` and `reportError` in favour of a general `reportDiagnostic`. * Introduce `DiagnosticReason`, `Severity` is an enum: This big commit makes `Severity` a simple enumeration, and introduces the concept of `DiagnosticReason`, which classifies the /reason/ why we are emitting a particular diagnostic. It also adds a monomorphic `DiagnosticMessage` type which is used for generic messages. * The `Severity` is computed (for now) from the reason, statically. Later improvement will add a `diagReasonSeverity` function to compute the `Severity` taking `DynFlags` into account. * Rename `logWarnings` into `logDiagnostics` * Add note and expand description of the `mkHoleError` function
* Bump ghc-prim version to 0.7.0Ryan Scott2020-07-021-1/+1

* Update testsuiteSylvain Henry2020-06-171-1/+1
| | | | | | | | | | | | | | * support detection of slow ghc-bignum backend (to replace the detection of integer-simple use). There are still some test cases that the native backend doesn't handle efficiently enough. * remove tests for GMP only functions that have been removed from ghc-bignum * fix test results showing dependent packages (e.g. integer-gmp) or showing suggested instances * fix test using Integer/Natural API or showing internal names

* Improve output from -ddump-typesSimon Peyton Jones2018-10-241-1/+1
| | | | | | | | | | | | | | | | | | This patch makes a number of improvements to the output generated by -ddump-types * Prints data constructor separately * Omits empty chunks of output I was driven initially by the unhelpful existing output for data constructors, but ended up doing some refactoring. Lots of error message wibbles, but nothing significant. Certainly no change in user behaviour. (NB: It is just possible that I have failed to cleanly separate this patch from the next one, about isPredTy and friends.)
* Better -ddump-typesSimon Peyton Jones2018-10-041-1/+1
| | | | | | | | | | | The debug flag -ddump-types is supposed to show the type of Ids, and the kinds of type constructors. It was doing the former but not the latter -- instead it was using showTyTying, which is actually less helpful when debugging. This patch changes it to print the kind and roles of the thing. I also made -ddump-types show pattern synonyms

* Simplify -ddump-json implementationMatthew Pickering2018-05-131-9/+1
| | | | | | | | | | | | | | | | | | | This patch takes the much simpler route of whenever the compiler tries to output something. We just dump a JSON document there and then. I think this should be sufficient to work with and anything more refined quickly got complicated as it was necessary to demarcate message scopes and so on.

* Add 'addWordC#' PrimOpSebastian Graf2018-05-051-2/+2
| | | | | | | | | | | | | | | | | | | This is mostly for congruence with 'subWordC#' and '{add,sub}IntC#'. I found 'plusWord2#' while implementing this, which both lacks documentation and has a slightly different specification than 'addWordC#', which means the generic implementation is unnecessarily complex. While I was at it, I also added lacking meta-information on PrimOps and refactored 'subWordC#'s generic implementation to be branchless.

* Add a flag to emit error messages as JSONMatthew Pickering2017-01-301-0/+9
This patch adds the flag `-ddump-json` which dumps all the compiler output as a JSON array. This allows tooling to more easily parse GHC's output to display to users. The flag is currently experimental and will hopefully be refined for the next release. In particular I have avoided any changes which involve significant refactoring and provided what is easy given the current infrastructure.
