      Fix second bug in Trac #4127 · 2c183f9b

      This bug concerned the awkward shadowing we do for 
      Template Haskell declaration brackets.  Lots of
      comments in

      ia64: switch handling of 'foreign import wrapper' (FIW) to libffi · e025c94f
      Sergei Trofimovich authored
      I tried to build darcs-2.4.4 with ghc-6.12.3 and got coredumps when darcs is used
      in interactive mode. I tried test from ticket #3516 and found out FIW code is broken.
      Instead of fixing it I just switched to libffi. Result built successfully, passed
      'foreign import wrapper' test from ticket #3516 and builds working darcs.

      * storage manager: preserve upper address bits on 64bit machines (thanks to zygoloid) · d12690d5
      Sergei Trofimovich authored
      Patch does not touch amd64 as it's address lengts is 48 bits at most, so amd64 is unaffected.
      
      the issue: during ia64 ghc bootstrap (both 6.10.4 and 6.12.3) I
      got the failure on stage2 phase:
          "inplace/bin/ghc-stage2"   -H32m -O -H64m -O0 -w ...

      And it helped!

      Fixing link failure of compiler on ia64 ('-Wl,' prefixed value passed directly to ld) · 615d88d1
      Sergei Trofimovich authored
          /usr/bin/ld -Wl,--relax -r -o dist-stage1/build/HSghc-6.10.4.o \
                                        dist-stage1/build/BasicTypes.o dist-stage1/build/DataCon.o ...
          /usr/bin/ld: unrecognized option '-Wl,--relax'
      
      If we just drop '-Wl,' part it will not help as '-r' and '--relax' are incompatible.
      
      Looks like '-Wl,--relax' was skipped by earlier binutils' ld as unknown option.
      Removing ia64 specific path.
