#10728: Add e.g. "-N<=4" in addition to the fixed "-N4" and variable "-N" RTS options -------------------------------------+------------------------------------- Reporter: rrnewton | Owner: MarcelineVQ Type: feature request | Status: patch Priority: normal | Milestone: Component: Runtime System | Version: 7.10.2 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #9221, #8224 | Differential Rev(s): Phab:D1650 Wiki Page: | -------------------------------------+------------------------------------- Comment (by hvr): First, the single-dash introducing a long-opt is confusing. But let's ignore that one for a moment. Moreover, in the context of `-Ndiv<n>` and `-Nsub<n>` I consider `-Nmax<n>` wrongly named: It should rather be named `-Nmin<n>` to avoid confusion: Intuitively, `-N<infixop><n>` denotes {{{N `infixop` <n>}}}, with the binary operators {{{#!hs min, max, add, sub, div, mul :: Int -> Int -> Int }}} and the obvious definitions, this would imply that `-Nmax4` means {{{N `max` 4}}} which is not what's implemented here. The description of the flag alone should rise red flags already: | -N'''max'''<x> chooses the '''min'''imum of processor count or x -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10728#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
