| Subject: StablePtrs and a NCG bug
|
|
| module Examples where
| import Foreign
| f x = return x >>= deRefStablePtr
|
| [qrczak ~/QForeign]$ ghc -c -fglasgow-exts -O -fasm-x86 Examples.hs
|
| panic! (the `impossible' happened):
| getRegister(x86,unary primop)
| (Prim deRefStablePtrzh Temp(B0StgStablePtr))
This means that the deRefStablePtrzh primop isn't implemented in the
NCG. You can work around this by going via C (-fvia-C). I guess
we should fix this, or at least produce a helpful error message.
