I don't understand the question...? That is a source file, it is not
#12414: Ill-formed or incorrect multiline string in compiler/main/GHC.hs -------------------------------------+------------------------------------- Reporter: ifigueroap | Owner: Type: bug | Status: closed Priority: lowest | Milestone: Component: Compiler | Version: 8.0.1 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ifigueroap): Replying to [comment:6 rwbarton]: produced by anything. GHC automatically runs it through CPP before compiling, because it has `{-# LANGUAGE CPP #-}`. The output of CPP is a valid Haskell module. Well, my point is that when running hothasktags, which internally runs cpphs and then tries to parse with haskell-src-exts I get the aforementioned "Illegal character in string gap", ''which in this particular case may mean that the output of the preprocessor is not a valid Haskell module.'' I'm not sure whether this is the case in the build process, as I didn't find how to get the post-processed file during compilation. To illustrate my point, if I manually run the preprocessor (in the compiler/main dir): {{{ cpphs -I../ -I../stage1 GHC.hs > GHC2.hs }}} (Note the two includes are for HsVersions.h in compiler/ and for ghc_autoconf.h in compiler/stage1). I get the "ill-formed" two-line string in the resulting GHC2.hs file. Of course I'm not sure what other flags are being passed to cpphs... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12414#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
