* | Tidy up the canonicaliserSimon Peyton Jones2012-02-164-189/+260
| | | | | | | | | | | | I have forgotten what the original driver for this change was. There is quite a bit of refactoring in TcCanonical; the rest is minor.
* | Change ATyVar to only have a *tyvar* not a *type* in itSimon Peyton Jones2012-02-169-97/+94
| | | | | | | | This isn't really a forced change, but is a useful tidy-up

* Define a quotRem CallishMachOp; fixes #5598Ian Lynagh2012-02-1411-448/+495
| | | | | This means we no longer do a division twice when we are using quotRem (on platforms on which the op is supported; currently only amd64).

* Refactoring, and fix a couple of SafeHaskell-related thingsSimon Marlow2012-02-141-33/+58
| | | | | | | | | When -XSafe is on: - ":load M" should default to adding M to the context (rather than *M). - "import M" should do the appropriate trust check Also various refactoring and comments added, hopefully the code is easier to read now.
* Revert "Don't add a bad import to the saved context."Simon Marlow2012-02-131-28/+17
| | | | | | | This reverts commit e5272d9bf2a65b7da8364803fcafbd2012b7de97. Reverting to fix validate regression, and pending a redesign of the changes.

This program exhibits contention for the block allocator when run with -N2 and greater without the fix: {-# LANGUAGE MagicHash, UnboxedTuples, BangPatterns #-} module Main where import Control.Monad import Control.Concurrent import System.Environment import GHC.IO import GHC.Exts import GHC.Conc main = do [m] <- fmap (fmap read) getArgs n <- getNumCapabilities ms <- replicateM n newEmptyMVar sequence [ forkIO $ busyWorkerB (m `quot` n) >> putMVar mv () | mv <- ms ] mapM takeMVar ms busyWorkerB :: Int -> IO () busyWorkerB n_loops = go 0 where go !n | n >= n_loops = return () | otherwise = do p <- (IO $ \s -> case newPinnedByteArray# 1024# s of { (# s', mbarr# #) -> (# s', () #) } ) go (n+1)

* Don't add a bad import to the saved context.David Terei2012-02-101-17/+28
| | | | | | Importing an unsafe module in GHCi under -XSafe would fail but still save that in the context so it would be retried on every subsequent import.
* Don't allow implicit qualified imports in GHCi when -XSafe on.David Terei2012-02-101-1/+6
| | | | | | It would be better to actually check the safety of the import but doing that requires some significant refactoring of code so punting for another day.

* | Complete fix of #5820Simon Peyton Jones2012-02-103-62/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two related changes in here a) Fix TcRnDriver.setInteractiveContext so that it initialises tcg_insts and tcg_fam_insts, as well as the corresponding tcg_inst_env and tcg_fam_inst_env fields. Vital! b) Fix FamInst.tcExtendLocalFamInstEnv for the GHCi case. It had a special HACK to allow family instances to be overridden in GHCi. Fair enough, but * It was only affecting the tcg_fam_inst_env, not tcg_fam_insts * It overrode home-package instances as well as ones entered at the GHCi prompt, which probably wasn't intended. I fixed both of these, and also narrowed the scope of what it does to override only *identical* instances, rather than any ones that conflict. If people yelp about this we can return to the question, but for now it narrows the range of the HACK

* | Put only local instances in the interactive context (fixes Trac #5820)Simon Peyton Jones2012-02-101-2/+2
|/ | | | | | | | In HscMain.hscDeclsWithLocaion, we were grabbing class instances from the tcg_inst_env field of the TcGblEnv. But that's wrong: that field contains all the *home-package* instances. Instead we need the tct_insts field, which has just the instances from the module being compiled.
