#9281: Rewrite `integer-gmp` to use only non-allocating GMP functions -------------------------------------+------------------------------------- Reporter: hvr | Owner: hvr Type: task | Status: patch Priority: normal | Milestone: 7.10.1 Component: libraries | Version: (other) | Keywords: integer-gmp Resolution: | Operating System: Unknown/Multiple Differential Revisions: Phab:D82 | Type of failure: None/Unknown Architecture: | Test Case: Unknown/Multiple | Blocking: Difficulty: Unknown | Blocked By: | Related Tickets: #8647 | -------------------------------------+------------------------------------- Comment (by hvr): fwiw, if you use `prim`-FFI imports instead of `ccall` , `... -> State# s -> State# s` as well as `... -> State# s -> (# s, Word# #)` already works. Is this maybe just a matter of replicating what's already done for `prim`-style FFI/Cmm calls? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9281#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
