I'm trying to fix http://hackage.haskell.org/trac/ghc/ticket/1015 (segv
on solaris with regex-posix). This bug only appears when using ghci. I
think it's something to do with weak pointers / finalizers, but my hacks
on the rts seem to not affect the stage2 compiler.
ie:
ghc$ cd rts
ghc/rts$ ... hack on rts ...
ghc/rts$ cd ../compiler
ghc/compiler$ make stage=2
ghc/compiler$ ../ghc/stage2-inplace/ghc --interactive
-- no effect??
If I, say, modify rts/Weak.c:scheduleFinalizers to print out what
finalizes are being run on each call, how do I make ghci with the stage2
compiler use this change?
Try this instead:
ghc$ cd rts
ghc/rts$ ... hack on rts ...
ghc/rts$ cd ../ghc
ghc/ghc$ make rebuild stage=2
in the new build system this will be:
ghc$ cd ghc
ghc/ghc$ make stage2
Cheers,
Simon
