      Cleanup sweep and fix a bug in RTS flag processing. · 5463b55b
      Simon Marlow authored
      This code has accumulated a great deal of cruft over the years, this
      pass cleans up a lot of the surrounding cruft but leaves the actual
      argument processing alone - so there's still more that could be done.
      Bug fixed:
        - ghc_rts_opts should not be subject to the --rtsopts setting.  If
          the programmer explicitly declares options with ghc_rts_opts, they
          shouldn't also have to accept command-line RTS options to make them

      real bug, spotted by Marcin Orczyk (thanks!).  I'm not sure if it lead
      to any actual crashes.

      gen_contents_index: Improve parsing of packages file · 159fdb19
      Ian Lynagh authored
      We are now more lenient in parsing the packages file, and
      we don't use any GNUisms. Based on a patch from Matthias Kilian.

      Force re-linking if the options have changed (#4451) · 814edf44
      Simon Marlow authored
      A common sequence of commands (at least for me) is this:
      $ ghc hello
      1 of 1] Compiling Main             ( hello.hs, hello.o )
      Linking hello ...
      $ ./hello +RTS -s
      hello: Most RTS options are disabled. Link with -rtsopts to enable them.
      $ ghc hello -rtsopts
      grr, nothing happened.  I could use -fforce-recomp, but if this was a
      large program I probably don't want to recompile it all again, so:
      $ rm hello
      removed `hello'
      $ ghc hello -rtsopts
      Linking hello ...
      $ ./hello +RTS -s
      ./hello +RTS -s
      Hello World!
                51,264 bytes allocated in the heap
                 2,904 bytes copied during GC
                43,808 bytes maximum residency (1 sample(s))
                17,632 bytes maximum slop
      With this patch, GHC notices when the options have changed and forces
      a relink, so you don't need to rm the binary or use -fforce-recomp.
      This is done by adding the pertinent stuff to the binary in a special
      section called ".debug-ghc-link-info":
      $ readelf -p .debug-ghc-link-info ./hello

      And GHC itself uses the readelf command to extract it when deciding
      whether to relink.  The reason for the name ".debug-ghc-link-info" is
      that sections beginning with ".debug" are removed automatically by
      This currently only works on Linux; Windows and OS X still have the
      old behaviour.

      By default, git will clone in autocrlf mode, which on Windows means
      we get '\r's added to the ghc-packages files.
