Comment:
I think I've now done this
{{{

* The templateHaskellOk check should only run in stage2
Because rtsIsProfiled is only available in stage2
Shall I push this patch? (1/2) [ynW...], or ? for more options: y
Mon Aug 23 14:34:39 BST 2010 [email protected]
* DPH should not even be built if GhcProfiled
It's not just when cleaning!
}}}
Ian: can you add a test? (I'm not sure where to put it so that it'll run
only when stage2 is profiled.) An example is
{{{
{-# LANGUAGE TemplateHaskell #-}
module Foo where
f x = $([| x |])
}}}
which now gives
{{{
simo...@cam-04-unx:~/tmp$ ~/builds/HEAD-1/inplace/bin/ghc-stage2 -c
T4255.hs
ghc-stage2: T4255.hs:1:14-28: You can't use Template Haskell with a
profiled compiler
Usage: For basic information, try the `--help' option.
}}}
