[GHC] #8602: Wrong argument order to Haskell pre-processor (-F, -pgmF, -optF)

8 Dec 2013

      ...
Additional arguments to the pre-processor can be passed in using the
 {{{-optF}}} option. These are fed to cmd on the command line after the
#8602: Wrong argument order to Haskell pre-processor (-F, -pgmF, -optF)

 So far, and that is what is documented

 three standard input and output arguments.

 However, {{{GHC 7.7.20131026}}} passes additional arguments (specified
 with {{{-optF}}}) before the three standard arguments.

 Steps to reproduce:

 {{{
 $ echo '{-# OPTIONS_GHC -F -pgmF ./foo.sh -optF bar #-}' > Foo.hs
 $ echo 'echo $*' > foo.sh
 $ chmod +x foo.sh
 $ ghci Foo.hs
 }}}

 Expected result: {{{Foo.hs Foo.hs /tmp/ghc16665_0/ghc16665_1.hspp bar}}}
 is printed to stdout

 Actual result: {{{bar Foo.hs Foo.hs /tmp/ghc16665_0/ghc16665_1.hspp}}} is
 printed to stdout
