#9696: readRawBufferPtr and writeRawBufferPtr allocate memory -------------------------------------+------------------------------------- Reporter: mergeconflict | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Runtime | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by mjmrotek): Replying to [comment:3 thomie]:
Also, there is a safe foreign import of `rtsSupportsBoundThreads` in GHC.IO.FD (and also some other module(s) in base), which seems quite unnecessary considering `rtsSupportsBoundThreads` simply returns a constant.
For a newcomer, to get acquainted with the patch submission process.
I did this part in https://phabricator.haskell.org/D1964 , grepping through HEAD didn't show any more safe imports of `rtsSupportsBoundThreads`. I didn't touch anything related to `readRawBufferPtr`, `writeRawBufferPtr`, or `throwErrnoIfRetryMayBlock`, though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9696#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
