* perf ci: Start searching form the performance baselineMatthew Pickering2021-12-221-3/+4
| | | | | | | | | | If you specify PERF_BASELINE_COMMIT then this can fail if the specific commit you selected didn't have perf test metrics. (This can happen in CI for example if a build fails on master). Therefore instead of just reporting all tests as new, we start searching downwards from this point to try and find a good commit to report numbers from.
* testsuite: Remove reqlib modifierMatthew Pickering2021-12-22123-7190/+6
| | | | | | | | | | | | | | | | | | | | The reqlib modifer was supposed to indicate that a test needed a certain library in order to work. If the library happened to be installed then the test would run as normal. However, CI has never run these tests as the packages have not been installed and we don't want out tests to depend on things which might get externally broken by updating the compiler. The new strategy is to run these tests in head.hackage, where the tests have been cabalised as well as possible. Some tests couldn't be transferred into the normal style testsuite but it's better than never running any of the reqlib tests. https://gitlab.haskell.org/ghc/head.hackage/-/merge_requests/169 A few submodules also had reqlib tests and have been updated to remove it. Closes #16264 #20032 #17764 #16561
* Fix panic trying to -ddump-parsed-ast for implicit fixityAlan Zimmerman2021-12-227-8/+185
| | | | | | | | | | | | | | A declaration such as infixr ++++ is supplied with an implicit fixity of 9 in the parser, but uses an invalid SrcSpan to capture this. Use of this span triggers a panic. Fix the problem by not recording an exact print annotation for the non-existent fixity source. Closes #20846
* ci: Fix master CIMatthew Pickering2021-12-221-1/+1
| | | | | I made a mistake in the bash script so there were errors about "$CI_MERGE_REQUEST_DIFF_BASE_SHA" not existing.

* Only use -ldl conditionally to fix T3807Greg Steuck2021-12-212-1/+7
| | | | | OpenBSD doesn't have this library and so the linker complains: ld.lld: error: unable to find library -ldl
* Use libc++ instead of libstdc++ on openbsd in addition to freebsdGreg Steuck2021-12-212-3/+6
| | | | | | | | This is not entirely accurate because some openbsd architectures use gcc. Yet we don't have ghc ported to them and thus the approximation is good enough. Fixes ghcilink006 test
* Give plugins a better interface (#17957)Sylvain Henry2021-12-2115-75/+91
| | | | | | | | | | | | Plugins were directly fetched from HscEnv (hsc_static_plugins and hsc_plugins). The tight coupling of plugins and of HscEnv is undesirable and it's better to store them in a new Plugins datatype and to use it in the plugins' API (e.g. withPlugins, mapPlugins...). In the process, the interactive context (used by GHCi) got proper support for different static plugins than those used for loaded modules. Bump haddock submodule
* Introduce -dlint flagBen Gamari2021-12-212-0/+30
| | | | | | As suggested in #20601, this is a short-hand for enabling the usual GHC-internal sanity checks one typically leans on when debugging runtime crashes.
* Rename -fcatch-bottoms to -fcatch-nonexhaustive-casesBen Gamari2021-12-215-10/+11
| | | | As noted in #20601, the previous name was rather misleading.
* rts: Add optional bounds checking in out-of-line primopsBen Gamari2021-12-211-0/+18
|
* codeGen: Introduce flag to bounds-check array accessesBen Gamari2021-12-2112-1/+242
| | | | | | | Here we introduce code generator support for instrument array primops with bounds checking, enabled with the `-fcheck-prim-bounds` flag. Introduced to debug #20769.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This place ensures that the default -dcore-lint option is disabled by default when collect_compiler_stats is used but you can still pass -dcore-lint as an additional option (see T1969 which tests core lint performance).

* Demand: `Eq DmdType` modulo `defaultFvDmd` (#20827)Sebastian Graf2021-12-171-5/+35
| | | | | | Fixes #20827 by filtering out any default free variable demands (as per `defaultFvDmd`) prior to comparing the assocs of the `DmdEnv`. The details are in `Note [Demand type Equality]`.
* Binary: make withBinBuffer safeCheng Shao2021-12-171-5/+1
| | | | | | | With this patch, withBinBuffer will construct a ByteString that properly captures the reference to the BinHandle internal MutableByteArray#, making it safe to convert a BinHandle to ByteString and use that ByteString outside the continuation.

* ci: Use correct metrics baselineMatthew Pickering2021-12-172-3/+13
| | | | | | | | | | | It turns out there was already a function in the CI script to correctly set the baseline for performance tests but it was just never called. I now call it during the initialisation to set the correct baseline. I also made the make testsuite driver take into account the PERF_BASELINE_COMMIT environment variable Fixes #20811

* Change isUnliftedTyCon to marshalablePrimTyCon (#20401)Krzysztof Gogolewski2021-12-178-203/+42
| | | | | | | | | | | | | | | | | | | | | | | | isUnliftedTyCon was used in three places: Ticky, Template Haskell and FFI checks. It was straightforward to remove it from Ticky and Template Haskell. It is now used in FFI only and renamed to marshalablePrimTyCon. Previously, it was fetching information from a field in PrimTyCon called is_unlifted. Instead, I've changed the code to compute liftedness based on the kind. isFFITy and legalFFITyCon are removed. They were only referred from an old comment that I removed. There were three functions to define a PrimTyCon, but the only difference was that they were setting is_unlifted to True or False. Everything is now done in mkPrimTyCon. I also added missing integer types in Ticky.hs, I think it was an oversight. Fixes #20401

* base: fix autoconf detection of C pointer typesCheng Shao2021-12-151-2/+2
| | | | | | | | We used to attempt compiling `foo_t val; *val;` to determine if `foo_t` is a pointer type in C. This doesn't work if `foo_t` points to an incomplete type, and autoconf will detect `foo_t` as a floating point type in that case. Now we use `memset(val, 0, 0)` instead, and it works for incomplete types as well.
* base: use `CUIntPtr` instead of `Ptr ()` as the autoconf detected Haskell ↵Cheng Shao2021-12-151-1/+1
| | | | | | | | | type for C pointers When autoconf detects a C pointer type, we used to specify `Ptr ()` as the Haskell type. This doesn't work in some cases, e.g. in `wasi-libc`, `clockid_t` is a pointer type, but we expected `CClockId` to be an integral type, and `Ptr ()` lacks various integral type instances.
* Plugin load order should follow the commandline order (fixes #17884)Andrei Barbu2021-12-159-6/+61
| | | | | | | In the past the order was reversed because flags are consed onto a list. No particular behavior was documented. We now reverse the flags and document the behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CodeOutput: LCGConfig, add handshake initLCGConfig Add two modules: GHC.CmmToLlvm.Config -- to hold the Llvm code gen config GHC.Driver.Config.CmmToLlvm -- for initialization, other utils CmmToLlvm: remove HasDynFlags, add LlvmConfig CmmToLlvm: add lcgContext to LCGConfig CmmToLlvm.Base: DynFlags --> LCGConfig Llvm: absorb LlvmOpts into LCGConfig CmmToLlvm.Ppr: swap DynFlags --> LCGConfig CmmToLlvm.CodeGen: swap DynFlags --> LCGConfig CmmToLlvm.CodeGen: swap DynFlags --> LCGConfig CmmToLlvm.Data: swap LlvmOpts --> LCGConfig CmmToLlvm: swap DynFlags --> LCGConfig CmmToLlvm: move LlvmVersion to CmmToLlvm.Config Additionally: - refactor Config and initConfig to hold LlvmVersion - push IO needed to get LlvmVersion to boundary between Cmm and LLvm code generation - remove redundant imports, this is much cleaner! CmmToLlvm.Config: store platformMisc_llvmTarget instead of all of platformMisc
* libiserv: Rename Lib module to IServBen Gamari2021-12-143-3/+3
| | | | As proposed in #20546.
* ghc-bin: Add --merge-objs modeBen Gamari2021-12-1413-27/+100
| | | | | | | | | | This adds a new mode, `--merge-objs`, which can be used to produce merged GHCi library objects. As future work we will rip out the object-merging logic in Hadrian and Cabal and instead use this mode. Closes #20712.
* compiler: Use withFile instead of bracketBen Gamari2021-12-141-2/+1
| | | | A minor refactoring noticed by hlint.
* compiler: Drop `Maybe ModLocation` from T_MergeForeignBen Gamari2021-12-143-8/+8
| | | | This field was entirely unused.
* users-guide: Fix documentation for -shared flagBen Gamari2021-12-141-3/+4
| | | | | | This flag was previously called `--mk-dll`. It was renamed to `-shared` in b562cbe381d54e08dcafa11339e9a82e781ad557 but the documentation wasn't updated to match.

* Ghci environment: Do not remove shadowed idsJoachim Breitner2021-12-1413-48/+199
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Names defined earier but shadowed need to be kept around, e.g. for type signatures: ``` ghci> data T = T ghci> let t = T ghci> data T = T ghci> :t t t :: Ghci1.T ``` and indeed they can be used: ``` ghci> let t2 = Ghci1.T :: Ghci1.T ghci> :t t2 t2 :: Ghci1.T ``` However, previously this did not happen for ids (non-types), although they are still around under the qualified name internally: ``` ghci> let t = "other t" ghci> t' <interactive>:8:1: error: • Variable not in scope: t' • Perhaps you meant one of these: ‘Ghci2.t’ (imported from Ghci2), ‘t’ (line 7), ‘t2’ (line 5) ghci> Ghci2.t <interactive>:9:1: error: • GHC internal error: ‘Ghci2.t’ is not in scope during type checking, but it passed the renamer tcl_env of environment: [] • In the expression: Ghci2.t In an equation for ‘it’: it = Ghci2.t ``` This fixes the problem by simply removing the code that tries to remove shadowed ids from the environment. Now you can refer to shadowed ids using `Ghci2.t`, just like you can do for data and type constructors. This simplifies the code, makes terms and types more similar, and also fixes #20455. Now all names ever defined in GHCi are in `ic_tythings`, which is printed by `:show bindings`. But for that commands, it seems to be more ergonomic to only list those bindings that are not shadowed. Or, even if it is not more ergonomic, it’s the current behavour. So let's restore that by filtering in `icInScopeTTs`. Of course a single `TyThing` can be associated with many names. We keep it it in the bindings if _any_ of its names are still visible unqualifiedly. It's a judgement call. This commit also turns a rather old comment into a test files. The comment is is rather stale and things are better explained elsewhere. Fixes #925. Two test cases are regressing: T14052(ghci) ghc/alloc 2749444288.0 12192109912.0 +343.4% BAD T14052Type(ghci) ghc/alloc 7365784616.0 10767078344.0 +46.2% BAD This is not unexpected; the `ic_tythings list grows` a lot more if we don’t remove shadowed Ids. I tried to alleviate it a bit with earlier MRs, but couldn’t make up for it completely. Metric Increase: T14052 T14052Type
