#15348: Enable two-step allocator on FreeBSD ----------------------------------------+--------------------------------- Reporter: bgamari | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 Keywords: | Operating System: FreeBSD Architecture: Unknown/Multiple | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+--------------------------------- Currently the two-step allocator is disabled on FreeBSD as the `MEM_NORESERVE` macro is undefined. It seems that FreeBSD provided this macro until 2014, when it was [[https://reviews.freebsd.org/D848|removed]] as it wasn't implemented in the kernel. Regardless, Viktor Dukhovni reports empirical evidence on `ghc-devs` that just plain `mmap` does what we want. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15348 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
