#8949: switch -msse2 to be on by default -------------------------------------+------------------------------------- Reporter: errge | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 (CodeGen) | Keywords: Resolution: | Architecture: x86 Operating System: Unknown/Multiple | Difficulty: Moderate (less Type of failure: Other | than a day) Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------- Comment (by tibbe): I'm fine with only doing `-msse2` for now. The amount of benefit we'll get from `-march=native` is growing. We're adding more intelligence to the code generator (e.g. `memcpy` will soon unroll to wider instructions if the target supports it, we have `popcnt` and `bswap`) and compiling with `-fllvm` should benefit too e.g. as code for the vector package would presumably compile to better assembly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8949#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
