[GHC] #8286: fdToHandle docs are wrong about non-blocking mode

#8286: fdToHandle docs are wrong about non-blocking mode ------------------------------------+------------------------------------- Reporter: duncan | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/unix | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- The docs for System.Posix.IO.fdToHandle state: {{{ fdToHandle :: Fd -> IO HandleSource Converts an Fd into a Handle that can be used with the standard Haskell IO library (see System.IO). GHC only: this function has the side effect of putting the Fd into non-blocking mode (O_NONBLOCK) due to the way the standard IO library implements multithreaded I/O. }}} The final paragraph is wrong. The code no longer does this. System.Posix.IO.fdToHandle ends up calling GHC.IO.Handle.FD.fdToHandle which has this comment: {{{ fdToHandle :: Posix.FD -> IO Handle fdToHandle fdint = do iomode <- Posix.fdGetMode fdint (fd,fd_type) <- FD.mkFD fdint iomode Nothing False{-is_socket-} -- NB. the is_socket flag is False, meaning that: -- on Windows we're guessing this is not a socket (XXX) False{-is_nonblock-} -- file descriptors that we get from external sources are -- not put into non-blocking mode, because that would affect -- other users of the file descriptor }}} So clearly, it is now deliberately not putting it into non-blocking mode. This can trip people up who expect that it does put it into non-blocking mode, when in fact they now have to do that manually. Fix is trivial: delete that paragraph from the docs for that function. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8286> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #8061: Support for Complex Double in Foreign Function Interface

#8061: Support for Complex Double in Foreign Function Interface ------------------------------------+------------------------------------- Reporter: dsamperi | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Currently the FFI only permits BASIC return types like Double, Int, Bool, etc., but NOT Complex Double (only slightly non-basic!). This makes it impossible to import a Fortran function (not subroutine) that returns a complex value. Adding support for Complex Double would make it easier to interface to external libs like BLAS and LAPACK; without this support wrapper C libs must be used, and these are not standardized (the Haskell package hs-linear-algebra currently has some problems related to this). Thus adding Foreign support for Complex Double (not just through Ptr) would open up access to a large collection of external Fortran libs for the Haskell community. Currently I get the message "Unacceptable return type in FFI" when I try to return IO (ComplexType). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8061> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #8256: adding locality levels to prefetch# and friends

#8256: adding locality levels to prefetch# and friends ------------------------------------+------------------------------------- Reporter: carter | Owner: carter Type: task | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #8252 ,#8107 | ------------------------------------+------------------------------------- currently in HEAD / 7.7, the prefetch primop only does the equivalent of __builtin_prefetch(ptr,0,3) (0 here denoting a read prefetch, 3 denoting "high locality, keep this in cache for a while") On modern hardware, we can do better! For many natural use case of prefetch in haskell, we have a streaming workload, so we want a prefetch to also hint that "once we've worked on a piece of memory, no need to keep it around for any period of time, don't pollute our memory with it" the attached patch takes each prefetchBlah# operation (where blah=ByteArray,MutableByteArray, or Addr) and replaces it with prefetchBlah0# through prefetchBlah3#, and passes the integer information through into the code generators. To make the engineering reasonable, I enriched MO_Prefetch_Data with an Int parameter (which must be a value between ranging 0-3). Theres probably a better way to model the locality paramter, but that maps directly to how its used in llvm code gen. This patch does not include a test case yet. (interestingly, currently the test suite doesn't have any tests for the prefetch primops as yet!). So that needs to be added. Also, theres no good reason for the prefetch ops to be LLVM only. worst case we could just treat them as noop's and drop them. But at least for x86, should be easy to add the support (though if anyone wants to add support for the ppc and sparc stuff, or help me do that, that'd be awesome too!) . I"ll look into doing that in a few days. theres probably some other things i'm overlooking. anyways, i'll attach a preliminary patch for feedback now -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8256> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
