Benchmarks game updated
Isaac Gouy from the Language Benchmarks game tells me that they're starting to use GHC 7.0.2, there are a few tweaks, new flags (e.g. the LLVM backend) and other experiments people might like to try. Additionally, there are a couple of build failures that should be fixed. http://shootout.alioth.debian.org/u64q/measurements.php?lang=ghc -- Don

Hello, As I see, some examples compilled with similar flags: /usr/local/src/ghc-7.0.2/bin/ghc --make -O2 -fglasgow-exts -rtsopts -funbox-strict-fields -fexcess-precision -fvia-c -optc-O3 spectralnorm.ghc-4.hs -o spectralnorm.ghc-4.ghc_run Does this flags enable LLVM optimizations in 7.0.2? -- Dmitriy

Does this flags enable LLVM optimizations in 7.0.2?
No, that uses C language generation and then passes the resulting C through gcc. To go through LLVM instead, you need to pass -fllvm instead of -fvia-c. Then the -optc-O3 will not be valid; instead, you'll want to play around with flags to -oplo and -optlc to pass them to the LLVM stages. -- Chris
