[project @ 2001-10-17 15:44:40 by simonpj] --------------------------- Better floating in CorePrep --------------------------- ** DO NOT MERGE ** [NB: this commit also changes the wrongly-named -ddump-sat flag to be called -ddump-prep ] Earlier fiddling with CorePrep meant that it was ANF-ing the top-level defn: x = length [True,False] to x = let s1 = False : [] s2 = True : s1 in length s2 This is Very Bad for big constant data structures, as show up in Happy-generated parsers, and that's why we get the big-block-alloc crash in hssource. Instead we want s1 = False : [] s2 = True : s1 x = length s2 This happens now, (I hope), but it's part of an ongoing jiggling process in the CoreTidy-CorePrep-CoreToStg part of the compiler, so it's possible I have broken something else.

[project @ 2001-10-17 13:16:03 by simonpj] ------------------------------------------- Desugar bindings into Rec groups more often [Part 2] ------------------------------------------- ** MERGE PLEASE ** [I forgot the unlifted case.] In rather obscure cases (involving functional dependencies) it is possible to get an AbsBinds [] [] (no tyvars, no dicts) which nevertheless has some "dictionary bindings". These come out of the typechecker in non-dependency order, so we need to Rec them just in case. It turns out to be a bit awkward. The smallest fix is to make dsLet always make a Rec; brutal but correct.

[project @ 2001-10-17 13:12:56 by simonmar] Use the smart constructor mkNote instead of the dumb constructor (Note) when rebuilding the expression after eta expansion.

[project @ 2001-10-16 10:01:13 by simonmar] Explicitly sign- or zero-extend the result of a ccall up to the word size if necessary. Recent discussion on glasgow-haskell-users@haskell.org suggests that this is the responsibility of the caller rather than the callee. We do it by wrapping the result in narrow{8,16,32}{Int,Word}# as appropriate, at desugaring time, because this way we only have to do it once instead of once per backend. Furthermore the narrowing is exposed to the simplifier which is generally a good thing.

[project @ 2001-10-15 16:03:04 by simonpj] -------------------------- Tidy up arity propagation (the saga continues) -------------------------- Turns out that it's not as easy as I thought. The code generator was assuming that (not . isLocalName) was enough to identify an imported thing (whose CgInfo should be right), but that's not true. Needs more thought. Meanwhile, I've made the code generator a bit more sensible about how it looks things up. But there's still a problem for GHCi: the unfoldings in the TypeEnv won't have CgIdInfo stuff. Sigh. Thinks.

[project @ 2001-10-15 15:06:01 by simonpj] -------------------------- Tidy up arity propagation -------------------------- Due to excessive complexity, correct arity information was getting lost on the way to interface files. As a result, a function that had CPR info __S SLm (say), was getting arity 0, and this confused the (old) CPR analyser ("lub of function and HasCPR"). I hope this fixes the above error (which showed up somewhere in compiling Edison), but I'm going to commit it right now anyway. Meanwhile I'll recompile Edison too. Details ~~~~~~~ Digging out the rather obscure cause made me tidy up the CgInfo stuff. The story is now * The CgInfo field of an Id gets attached to the Id *only* in the TypeEnv of the ModuleDetails, during CoreTidy. This ModuleDetails stuff is used a) to generate the interface file b) to import into other modules in GHCi * No CgInfo field is in the CoreBindings which are passed downsteam to CorePrep and thence CodeGen. Quite right too... it's the downstream stuff that *generates* the CgInfo. * But the Arity field *is* now passed on through CoreTidy (like strictness info) since it is usefully used by CorePrep. * On the way I simplified the ArityInfo field of an IdInfo to simply Arity instead of Maybe Arity
