Diatchki <diatchki@…>
Make type-level evaluation work with :kind! The main change is to add a case to `reduceTyFamApp_maybe` to evaluate built-in type constructors (e.g., (+), (*), and friends). To avoid problems with recursive modules, I moved the definition of TcBuiltInSynFamily from `FamInst` to `FamInstEnv`. I am still not sure if this is the right place. There is also a wibble that it'd be nice to fix: when we evaluate a built-in type function, using`sfMatchFam`, we get a `TcCoercion`. However, `reduceTyFamApp_maybe` needs a `Corecion`. I couldn't find a nice way to convert between the two, so I resorted to a bit of hack (marked with `XXX`). The hack is that we happen to know that the built-in constructors for the type-nat functions always return coercions of shape `TcAxiomRuleCo`, with no assumptions, so it easy to convert `TcCoercion` to `Coercion` in this one case. This is enough to make things work, but it is clearly a cludge.

Warn if you use ANN annotations with a stage-1 compiler (Trac #4268) This makes us give a civilised warning when we hit an {-# ANN f foo #-} pragma in a stage-1 compiler. We decided that, since it's a pragma, it does not need a language extension flag to enable it.

Fix egregious omission in CSE (Trac #5996) This patch fixes a bad omission in CSE, thanks to 'michaelt' for spotting it, and correctly identifying the fix (in cseRhs). The trouble was with x1 = C a b x2 = C x1 b y1 = C a b y2 = C y1 b we were not commoning up y2=x2, because we failed to substitute y1:=x1, so y2's RHS looked different to x2's I also refactoring, so taht the cs_map in a CSEnv map is cs_map :: CoreMap (OutExpr, Id) instead of cs_map :: CoreMap (OutExpr, OutExpr) Much nicer! This doesn't make much difference to allocation, but it gives a surprisingly big benefit to binary size. -------------------------------------------------------------------------------- Program Size Allocs Runtime Elapsed TotalMem -------------------------------------------------------------------------------- ansi -1.7% -0.8% 0.00 0.00 +0.0% bspt -1.6% -1.5% 0.01 0.01 +0.0% cacheprof -1.8% -0.2% +1.6% +1.9% +2.7% fft -1.4% -1.3% 0.06 0.06 +11.1% ida -1.4% -1.0% 0.12 0.12 +0.0% rfib -1.4% -0.1% 0.03 0.03 +0.0% scs -1.6% -0.1% +1.5% +1.5% +0.0% spectral-norm -1.3% -0.1% -0.2% -0.2% +0.0% tak -1.4% -0.1% 0.02 0.02 +0.0% veritas -1.4% -0.1% 0.00 0.00 +0.0% -------------------------------------------------------------------------------- Min -2.5% -1.5% -11.8% -11.8% -8.0% Max -1.0% +0.0% +2.7% +2.5% +11.1% Geometric Mean -1.3% -0.1% -2.6% -2.6% +0.0%

Improve eta expansion (again) The presenting issue was that we were never eta-expanding f (\x -> case x of (a,b) -> \s -> blah) and that meant we were allocating two lambdas instead of one. See Note [Eta expanding lambdas] in SimplUtils. However I didn't want to eta expand the lambda, and then try all over again for tryEtaExpandRhs. Yet the latter is important in the context of a let-binding it can do simple arity analysis. So I ended up refactoring CallCtxt so that it tells when we are on the RHS of a let. I also moved findRhsArity from SimplUtils to CoreArity. Performance increases nicely. Here are the ones where allocation improved by more than 0.5%. Notice the nice decrease in binary size too. -------------------------------------------------------------------------------- Program Size Allocs Runtime Elapsed TotalMem -------------------------------------------------------------------------------- ansi -2.3% -0.9% 0.00 0.00 +0.0% bspt -2.1% -9.7% 0.01 0.01 -33.3% fasta -1.8% -11.7% -3.4% -3.6% +0.0% fft -1.9% -1.3% 0.06 0.06 +11.1% reverse-complem -1.9% -18.1% -1.9% -2.8% +0.0% sphere -1.8% -4.5% 0.09 0.09 +0.0% transform -1.8% -2.3% -4.6% -3.1% +0.0% -------------------------------------------------------------------------------- Min -3.0% -18.1% -13.9% -14.6% -35.7% Max -1.3% +0.0% +7.7% +7.7% +50.0% Geometric Mean -1.9% -0.6% -2.1% -2.1% -0.2%

SysTools.getTempDir: don't retry after catching a does-not-exist error Previously, a command like $ ghc -tmpdir blah Foo where the directory blah/ does not exist, would loop forever: getTempDir would repeatedly try to create a temporary subdirectory inside blah/, catching the does-not-exist error thrown by createDirectory and retrying, in vain, with another suffix. Now instead the above compiler invocation will fail with an error: blah/ghc25781_0: createDirectory: does not exist (No such file or directory)
