Building GHC for performance testing

Hi, I'd like to set up a performance build bot for GHC, but before I can do that I need a script that reliably builds GHC and runs nofib. Do we have such a script? Here's a strawman proposal for one: cabal install happy alex git clone git://git.haskell.org/ghc.git cd ghc ./sync-al

What is this file? nofib/real/HMMS/lib/haskell/Builtin.hi It's a mystery! Can we delete it? Simon ___ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs

Please consider this as a pull request. It fixes an ugly code size blowup that trips the PowerPC assembler (NCG mode). Cheers, Gabor ___ ghc-devs mailing lis

Re: Building GHC for performance testing

There's also the issue that certain vms disable some simd instructions(I think), and while we don't have many libs that are simd heavy as yet this could be an issue in certain future benchmarks? (I could be completely wrong though. ) On Thursday, March 6, 2014, Herbert Valerio Riedel wrote: > On

Re: [PATCH] time library fix for PowerPC

Rejected. The time library git repo only takes converted patches from its darcs upstream, see . However, I can see about making the equivalent change in , or you can send me a darcs patch. -- Ashley

Where's the implementation of newArray#

Is the below code it (from rts/PrimOps.cmm)? Does it being in PrimOps.cmm mean that it's always out-of-line? stg_newArrayzh ( W_ n /* words */, gcptr init ) { W_ words, size; gcptr p, arr; again: MAYBE_GC(again); // the mark area contains one byte for each 2^MUT_ARR_PTRS_CARD_BIT

Re: Building GHC for performance testing

Hello Johan, Off the top of my head: Technically speaking, the compiler does not have to be optimized to do build tests; just the libraries. So you could probably make the builds run a bit faster this way. Your command for nofib will only run the "standard" benchmarks; to run, for example, the

RE: new Windows build problem

Actually, the two problems seem to be the same. A fresh build from scratch yields libraries/random/ghc.mk:5: recipe for target 'libraries/random/dist-install/build/System/Random.o' failed make[1]: *** [libraries/random/dist-install/build/System/Random.o] Segmentation fault Then sniping the co

Emitting calls to functions defined in PrimOps.cmm from the code gen

Hi, I'm trying to make allocation of arrays of small, statically-known size inline. For large or unknown size I just want to call the existing stg_newArrayzh function. In code: doNewArrayOp :: DynFlags -> CmmFormal -> CmmExpr -> FCode () doNewArrayOp dflags res_r (CmmLit (CmmInt n _)) | n <= inli
