* Replace CPP assertions with Haskell functionsSylvain Henry2021-05-12178-909/+1061
| | | | | | | | | | | | | | | There is no reason to use CPP. __LINE__ and __FILE__ macros are now better replaced with GHC's CallStack. As a bonus, assert error messages now contain more information (function name, column). Here is the mapping table (HasCallStack omitted): * ASSERT: assert :: Bool -> a -> a * MASSERT: massert :: Bool -> m () * ASSERTM: assertM :: m Bool -> m () * ASSERT2: assertPpr :: Bool -> SDoc -> a -> a * MASSERT2: massertPpr :: Bool -> SDoc -> m () * ASSERTM2: assertPprM :: m Bool -> SDoc -> m ()

| | | | | | | | | | | tryWW used to always returns an Id with a zapped: * DmdEnv * Used Once info except in the case where the ID was guaranteed to be inlined. We now also zap the info in that case. Fixes #19818.

* hadrian: Don't always links against libffiMatthew Pickering2021-05-111-2/+1
| | | | | | | | | The RTS flag `ffi` is set to either True or False depending on whether we want to link against `libffi`, therefore in order to work out whether to add the build tree to the arguments we check whether `ffi` is in the extraLibs or not before adding the argument. Fixes #16022

* Fix strictness and arity info in SpecConstrSimon Peyton Jones2021-05-117-77/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In GHC.Core.Opt.SpecConstr.spec_one we were giving join-points an incorrect join-arity -- this was fallout from commit c71b220491a6ae46924cc5011b80182bcc773a58 Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Thu Apr 8 23:36:24 2021 +0100 Improvements in SpecConstr * Allow under-saturated calls to specialise See Note [SpecConstr call patterns] This just allows a bit more specialisation to take place. and showed up in #19780. I refactored the code to make the new function calcSpecInfo which treats join points separately. In doing this I discovered two other small bugs: * In the Var case of argToPat we were treating UnkOcc as uninteresting, but (by omission) NoOcc as interesting. As a result we were generating SpecConstr specialisations for functions with unused arguments. But the absence anlyser does that much better; doing it here just generates more code. Easily fixed. * The lifted/unlifted test in GHC.Core.Opt.WorkWrap.Utils.mkWorkerArgs was back to front (#19794). Easily fixed. * In the same function, mkWorkerArgs, we were adding an extra argument nullary join points, which isn't necessary. I added a test for this. That in turn meant I had to remove an ASSERT in CoreToStg.mkStgRhs for nullary join points, which was always bogus but now trips; I added a comment to explain.

* EPA: Use custom AnnsIf structure for HsIf and HsCmdIfAlan Zimmerman2021-05-119-16/+72
| | | | | | | This clearly identifies the presence and location of optional semicolons in an if statement. Closes #19813
* Minor refactoring in WorkWrapSimon Peyton Jones2021-05-111-15/+7
| | | | | | This patch just does the tidying up from #19805. No change in behaviour.
* Expand Note [Data con representation].Andreas Klebinger2021-05-111-4/+30
| | | | Not perfect. But I consider this to be a documentation fix for #19789.
* EPA: properly capture leading semicolons in statement listsAlan Zimmerman2021-05-097-8/+24
| | | | | | | | | | | | | | For the fragment blah = do { ; print "a" ; print "b" } capture the leading semicolon before 'print "a"' in 'al_rest' in AnnList instead of in 'al_trailing'. Closes #19798
* EPA: update some comments in Annotations.Alan Zimmerman2021-05-081-119/+82
| | | | Follow-up from !2418, see #19579
* Fix newtype eta-reductionSimon Peyton Jones2021-05-078-18/+130
| | | | | | | | The eta-reduction we do for newype axioms was generating an inhomogeneous axiom: see #19739. This patch fixes it in a simple way; see GHC.Tc.TyCl.Build Note [Newtype eta and homogeneous axioms]
* rts: Correctly call pthread_setname_np() on NetBSDPHO2021-05-074-5/+34
| | | | | | NetBSD supports pthread_setname_np() but it expects a printf-style format string and a string argument. Also use pthread for itimer on this platform.

* Allow visible type application for levity-poly data consSimon Peyton Jones2021-05-0729-387/+707
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch was driven by #18481, to allow visible type application for levity-polymorphic newtypes. As so often, it started simple but grew: * Significant refactor: I removed HsConLikeOut from the client-independent Language.Haskell.Syntax.Expr, and put it where it belongs, as a new constructor `ConLikeTc` in the GHC-specific extension data type for expressions, `GHC.Hs.Expr.XXExprGhcTc`. That changed touched a lot of files in a very superficial way. * Note [Typechecking data constructors] explains the main payload. The eta-expansion part is no longer done by the typechecker, but instead deferred to the desugarer, via `ConLikeTc` * A little side benefit is that I was able to restore VTA for data types with a "stupid theta": #19775. Not very important, but the code in GHC.Tc.Gen.Head.tcInferDataCon is is much, much more elegant now. * I had to refactor the levity-polymorphism checking code in GHC.HsToCore.Expr, see Note [Checking for levity-polymorphic functions] Note [Checking levity-polymorphic data constructors]

* [testlib/driver] denoiseMoritz Angermann2021-05-072-6/+11
| | | | | | | | | | this prevents the testlib/driver to be overly noisy, and will also kill some noise produiced by the aarch64-darwin cc (for now).

* hadrian: Don't depend upon bash from PATHBen Gamari2021-05-066-7/+30
| | | | | | | | Previously Hadrian depended implicitly upon whatever `bash` it found in `PATH`, offerring no way for the user to override. Fix this by detecting `sh` in `configure` and passing the result to Hadrian. Fixes #19797.
