| | | | | | | Using `ghc-prim <= 0.6.1` is somewhat dodgy from a PVP point of view, as it makes it awkward to support new minor releases of `ghc-prim`. Let's instead use `< 0.7`, which is the idiomatic way of expressing PVP-compliant upper version bounds.

* Make GHC (the library) flexible in the choice of integer libraryJoachim Breitner2018-10-031-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We have more and more users of GHC as a library, for example the Haskell-to-WebAssembly-compiler https://github.com/tweag/asterius. These need to make different decisions about various aspects of code generation than the host compiler, and ideally GHC-the-library allows them to set the `DynFlags` as needed. This patch adds a new `DynFlag` that configures which `integer` library to use. This flag is initialized by `cIntegerLibraryType` (as before), and is only used in `CorePrep` to decide whether to use `S#` or not. The other code paths that were varying based on `cIntegerLibraryType` are no now longer varying: The trick is to use `integer-wired-in` as the `-this-unit-id` when compiling either `integer-gmp` or `integer-simple`. Test Plan: Validate is happy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's how the rube goldberg machine triggered the old bug: 1. If you have a file gmp/config.mk.in, then Cabal will create a generated file in $DIST/build/gmp/config.mk 2. When you attempt to load inplace integer-gmp via GHCi, it will ask gcc (aka clang on OS X) for the file name of 'gmp', with base directory set to $DIST/build 3. There is a folder named 'gmp', and so this folder is returned as the 'library' for gmp 4. GHCi loadArchive chokes to death trying to open a library that is actually a folder This patch solves the problem by breaking the chain at (1): if we don't put config.mk in a folder named gmp, NO PROBLEM.

| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This came up when trying to build GHC HEAD with nix. We do not set CCX for integer-gmp when running ./configure. We do this however for libffi. The result is, that if CCX is not set, we default to the system one, of which there might be none (as in nixos's case). This will not show on a debian+nix or similar setup, where the system `cxx` is still in place, and only shows up when the system tries hard to sandbox everything (even cxx) as nixOS does.

| | | | | | | | | | | | | | | | | | | | | | | | | These two special cases were created in D2278 by mechanically inlining negateInteger into plusInteger. They aren't needed (the `minusInteger (S# x#) (S# y#)` case already handles all values correctly), and they can never help by avoiding an allocation, unlike the original special case in plusInteger, since we still have to allocate the result. Removing these special cases will save a couple comparisons and conditional branches in the common case of subtracting two small Integers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In `x shiftR y`, any of the following conditions cause an abort: - `x` is a negative big integer - The size of `x` and `y` is a multiple of `GMP_NUMB_BITS` - The bit of the absolute value of `x` is filled with `1` For example: Assuming `GMP_NUMB_BITS = 2`, the processing of `-15 shiftR 2` is as follows: 1. -15 = -1111 (twos complement: 10001) 2. right shift 2 (as a positive number) -> 0011 3. Due to the shift larger than GMP_NUMB_BITS, the size of the destination is decreasing (2bit) -> 11 4. Add 1, and get carry: (1) 00 5. abort I fixed it that the destination size does not decrease in such a case. Test Plan: I tested the specific case being reported.

Here are some of the pieces of that proposal: * Some of RuntimeRep's constructors have been shortened. * TupleRep and SumRep are now parameterized over a list of RuntimeReps. * This means that two types with the same kind surely have the same representation. Previously, all unboxed tuples had the same kind, and thus the fact above was false. * RepType.typePrimRep and friends now return a *list* of PrimReps. These functions can now work successfully on unboxed tuples. This change is necessary because we allow abstraction over unboxed tuple types and so cannot always handle unboxed tuples specially as we did before. * We sometimes have to create an Id from a PrimRep. I thus split PtrRep * into LiftedRep and UnliftedRep, so that the created Ids have the right strictness. * The RepType.RepType type was removed, as it didn't seem to help with * much. * The RepType.repType function is also removed, in favor of typePrimRep. * I have waffled a good deal on whether or not to keep VoidRep in TyCon.PrimRep. In the end, I decided to keep it there. PrimRep is *not* represented in RuntimeRep, and typePrimRep will never return a list including VoidRep. But it's handy to have in, e.g., ByteCodeGen and friends. I can imagine another design choice where we have a PrimRepV type that is PrimRep with an extra constructor. That seemed to be a heavier design, though, and I'm not sure what the benefit would be. * The last, unused vestiges of # (unliftedTypeKind) have been removed. * There were several pretty-printing bugs that this change exposed; * these are fixed. * We previously checked for levity polymorphism in the types of binders. * But we also must exclude levity polymorphism in function arguments. This is hard to check for, requiring a good deal of care in the desugarer. See Note [Levity polymorphism checking] in DsMonad. * In order to efficiently check for levity polymorphism in functions, it * was necessary to add a new bit of IdInfo. See Note [Levity info] in IdInfo. * It is now safe for unlifted types to be unsaturated in Core. Core Lint * is updated accordingly. * We can only know strictness after zonking, so several checks around * strictness in the type-checker (checkStrictBinds, the check for unlifted variables under a ~ pattern) have been moved to the desugarer. * Along the way, I improved the treatment of unlifted vs. banged * bindings. See Note [Strict binds checks] in DsBinds and #13075. * Now that we print type-checked source, we must be careful to print * ConLikes correctly. This is facilitated by a new HsConLikeOut constructor to HsExpr. Particularly troublesome are unlifted pattern synonyms that get an extra void# argument. * Includes a submodule update for haddock, getting rid of #. * New testcases: typecheck/should_fail/StrictBinds typecheck/should_fail/T12973 typecheck/should_run/StrictPats typecheck/should_run/T12809 typecheck/should_fail/T13105 patsyn/should_fail/UnliftedPSBind typecheck/should_fail/LevPolyBounded typecheck/should_compile/T12987 typecheck/should_compile/T11736 * Fixed tickets: #12809 #12973 #11736 #13075 #12987 * This also adds a test case for #13105. This test case is * "compile_fail" and succeeds, because I want the testsuite to monitor the error message. When #13105 is fixed, the test case will compile cleanly.

Needs a version test so I resurrected the old test we had (sorry rwbarton!) - I've *undeprecated* -package-name, so that we are in the same state as GHC 7.10, since the "correct" flag will have only entered circulation in GHC 8.0. - I removed -package-key.
