#13844: Surprising behavior with CPP extension -------------------------------------+------------------------------------- Reporter: deech | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 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: -------------------------------------+------------------------------------- The CPP language extension performs macro substitutions in Haskell comments. 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
