#11312: GHC inlining primitive string literals can affect program output -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Incorrect result Unknown/Multiple | at runtime Test Case: | Blocked By: Blocking: | Related Tickets: #11292 Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- First noted in #11292, this program, when compiled with `-O1` or higher: {{{#!hs {-# LANGUAGE MagicHash #-} module Main (main) where import GHC.Exts (Addr#, isTrue#) import GHC.Prim (eqAddr#) data A = A { runA :: Addr# } a :: A a = A "a"# main :: IO () main = print (isTrue# (eqAddr# (runA a) (runA a))) }}} will result in the following after inlining: {{{ Main.main2 = case GHC.Prim.tagToEnum# @ GHC.Types.Bool (GHC.Prim.eqAddr# "a"# "a"#) of _ [Occ=Dead] { GHC.Types.False -> GHC.Show.shows26; GHC.Types.True -> GHC.Show.shows24 } }}} As a result, there are two of the same string constant with different addresses, which causes `eqAddr#` to return `False`. If compiled without optimizations, `"a"#` is not inlined, and as a result, `eqAddr#` returns `True`. Two questions: 1. Is this okay semantics-wise? Or is this a necessary risk when working with primitive string literals, and should programmers judiciously use `{-# NOINLINE #-}` with them? 2. Is this okay from a code duplication standpoint? As Reid Barton noted in #11292, `"a"#` is duplicated due to inlining. In this example, not much is duplicated, but if it were a longer string constant, that could result in a noticeable increase in the object file size. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11312> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #13257: out-of-range warnings for negative literals, without -XNegativeLiterals

#13257: out-of-range warnings for negative literals, without -XNegativeLiterals -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- By default (without `NegativeLiterals`) a negated literal `-1` is desugared as `negate (fromInteger 1)`. Hence the existing out-of-range literal warning doesn't trigger for `-1 :: Word`. But we could also recognize the pattern `negate (fromInteger lit)`, and give a warning when `-lit` is out-of-range (for `Word`, this is whenever `lit` is positive). Actually this could apply to signed integer types too: if we recognized `negate (fromInteger lit)` in preference to `fromInteger lit`, we could correctly not warn about `-128 :: Int8`, even when `NegativeLiterals` is not enabled. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13257> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#13366: addCStub doesn't allow control over compiler flags or source file file -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Currently if you pass a C source file on the GHC command line you can control whether the compiler treats it as C or C++ via the it's extension: GCC will treat a file ending in `.c` as C, whereas `.cpp` is treated as C++. However, we currently have no means of controlling what language a stub added with in Template Haskell with `addCStub` will be treated as. Consequently it is currently impossible to compile a C++ source file with `addCStub` without using `-optc`. Moreover, you can't have mixed C/C++ stubs at all. It really seems like this interface should be amended to fix this before we release it in 8.2. Perhaps `addCStub` should accept both the source and a set of compiler flags which will be added to the usual flags (allowing one to pass `-x c++` to the compiler when compiling C++ files)? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13366> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#13543: Improve demand analysis for join points -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Consider {{{ g :: (Int,Int) -> Int g (p,q) = p+q f :: Int -> Int -> Int f x p = g (join j y = (p,y) in case x of True -> j 3 False -> j 4) }}} If `j` was a vanilla function definition, we'd analyse its body with `evalDmd`, and think that it was lazy in `p`. But for a join point we can do better. We know that `j`'s body (if evaluated at all) will be evaluated with the demand that consumes the entire join-binding, in this case the argument demand from `g`. Whizzo! `g` evaluates both components of its arugment pair, so j is strict in `p`. So, when analysing a join point, we can analyse its body with the demand from the entire join-binding.

I see why it does but it seems like eliding the comments before pre-processing would be less surprising. Eg. compiling: {{{#!hs {-# LANGUAGE CPP -#} -- | Some folder foo/bar/* }}} gives the error: {{{ error: unterminated comment -- | Some folder foo/bar/* }}} because the `/*` in the comment is interpreted as starting a C comment. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13844> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

B10])) print $ qaax B1 }}} When `Char` or ''enum-like'' ADT is returned, I see lots of case branches, which only differ in the first instruction. E.g. {{{ c30l: // global R1 = stg_CHARLIKE_closure+1649; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; c30m: // global R1 = stg_CHARLIKE_closure+1665; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; u30Z: // global if (_c30p::I64 < 9) goto c30n; else goto c30o; c30n: // global R1 = stg_CHARLIKE_closure+1681; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; c30o: // global R1 = stg_CHARLIKE_closure+1697; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; }}} It would be nice to factor out the common tails, e.g. by branching to the first tail already emitted. Bonus points for rewriting switch tables to contain the above numbers and compile to a lookup + common code. This is what I am talking about: {{{ c307: // global _s2ON::P64 = R1; _c30j::P64 = _s2ON::P64 & 7; switch [1 .. 7] _c30j::P64 { case 1 : goto c30d; case 2 : goto c30e; case 3 : goto c30f; case 4 : goto c30g; case 5 : goto c30h; ... } ... c30h: // global R1 = stg_CHARLIKE_closure+1617; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; c30g: // global R1 = stg_CHARLIKE_closure+1601; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; c30f: // global R1 = stg_CHARLIKE_closure+1585; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; c30e: // global R1 = stg_CHARLIKE_closure+1569; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; c30d: // global R1 = stg_CHARLIKE_closure+1553; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; }}} There should be an array [1553, 1569, 1585, ...] and each case should be the same: {{{ R1 = stg_CHARLIKE_closure; R1 = R1 + array[tag]; Sp = Sp + 8; call (P64[Sp])(R1) args: 8, res: 0, upd: 8; }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/14372> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#14335: Annotations aren't supported with -fexternal-interpreter -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.2.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- It seems that using `{-# ANN #-}` pragmas from a plugin cause GHC to crash when run with `-fexternal-interpreter` with {{{ ghc: this operation requires -fno-external-interpreter }}} It seems that the culprit is likely the use of `wormhole` in `convertAnnotationWrapper`. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/14335> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
