Hi all, I just ran nofib on current HEAD and compared it to 7.6.2 on my 64-bit Linux machine. There are some regressions I think we should look into before a release: -------------------------------------------------------------------------------- Program Size Allocs Runtime Elapsed TotalMem -------------------------------------------------------------------------------- anna -0.8% +1.5% 0.08 0.08 +0.0% ansi -0.5% +0.5% 0.00 0.00 +0.0% atom -0.9% -0.0% -3.1% -0.8% +0.0% awards -0.9% +0.1% 0.00 0.00 +0.0% banner +0.1% +2.2% 0.00 0.00 +0.0% bernouilli -0.6% +2.7% 0.12 0.13 +0.0% boyer -0.7% +0.0% 0.03 0.04 +0.0% boyer2 -0.1% +0.0% 0.01 0.01 +0.0% bspt -0.6% -0.0% 0.01 0.02 +0.0% cacheprof -0.9% +6.9% +0.8% +4.0% +0.0% calendar -0.9% +0.1% 0.00 0.00 +0.0% cichelli -0.1% -0.0% 0.06 0.06 +9.4% circsim -0.7% +0.1% +1.6% +7.0% +13.6% clausify -0.8% +0.0% 0.03 0.03 +0.0% comp_lab_zift -0.7% +0.0% 0.14 0.14 -12.5% compress -0.1% +0.0% 0.12 0.13 +0.0% compress2 -0.0% +0.0% 0.12 0.14 +2.3% constraints -0.8% +0.0% -3.3% -0.7% +0.0% cryptarithm1 -0.1% +0.0% +2.1% +4.1% +0.0% cryptarithm2 -0.0% -0.8% 0.01 0.01 +0.0% cse -0.0% -0.0% 0.00 0.00 +0.0% eliza +0.1% +7.7% 0.00 0.00 +0.0% event -0.8% +0.0% 0.09 0.10 -8.7% exp3_8 -0.8% +0.0% 0.15 0.15 +100.0% expert -0.2% +18.4% 0.00 0.00 +0.0% fem +1.5% +0.5% 0.02 0.02 +0.0% fft -0.9% +0.0% 0.02 0.03 +0.0% fft2 +3.7% +31.9% 0.05 0.05 +20.0% fibheaps -1.0% +0.3% 0.03 0.03 +0.0% fish -0.0% -0.0% 0.01 0.01 +0.0% fluid -1.3% +13.0% 0.01 0.01 +0.0% fulsom -0.2% -0.0% 0.19 0.20 +8.3% gamteb -0.7% -0.2% 0.03 0.04 +0.0% gcd -0.8% +0.0% 0.02 0.03 +0.0% gen_regexps +0.0% +2.2% 0.00 0.00 +0.0% genfft -0.8% -0.3% 0.03 0.03 +0.0% gg -0.6% +40.4% 0.01 0.02 +50.0% grep -1.8% +2.3% 0.00 0.00 +0.0% hidden -0.7% +3.5% +4.1% +7.6% +0.0% hpg -1.3% -1.3% 0.05 0.10 +0.0% ida -0.7% -1.0% 0.07 0.08 +11.1% infer -0.9% +0.5% 0.05 0.05 +30.0% integer -0.8% +1.1% +1.1% +2.3% +0.0% integrate -0.9% +56.2% 0.20 0.23 +1.0% kahan -0.9% +144.9% +77.6% +78.4% +0.0% knights -0.1% -0.4% 0.01 0.01 +0.0% lcss -0.7% +0.7% -24.3% -18.4% +1.9% life -0.2% +0.0% 0.16 0.16 +0.0% lift -0.0% +0.1% 0.00 0.00 +0.0% listcompr -0.1% -0.0% 0.06 0.06 +0.0% listcopy -0.1% -0.0% 0.06 0.06 +0.0% maillist +0.0% +1.9% 0.02 0.04 +16.5% mandel -0.8% +0.0% 0.05 0.05 +0.0% mandel2 -0.1% -4.0% 0.00 0.01 +0.0% minimax -0.2% -0.0% 0.00 0.00 +0.0% mkhprog -0.1% +1.1% 0.00 0.00 +0.0% multiplier -1.2% +0.0% 0.07 0.08 +0.0% nucleic2 -3.3% +19.5% 0.05 0.05 +0.0% para -0.0% +25.0% 0.22 0.23 +0.0% paraffins -0.8% +0.0% 0.06 0.08 +7.5% parser -1.3% +22.2% 0.03 0.03 +0.0% parstof -0.5% +4.6% 0.01 0.00 +0.0% pic +0.5% +0.0% 0.00 0.00 +0.0% power -1.0% +0.0% -0.5% +1.0% +0.0% pretty -0.2% +0.0% 0.00 0.00 +0.0% primes -0.8% -0.0% 0.04 0.05 +0.0% primetest -0.7% +0.0% 0.07 0.07 +0.0% prolog -0.2% +16.0% 0.00 0.00 +0.0% puzzle -0.1% -2.1% 0.09 0.10 +0.0% queens -0.8% +0.0% 0.02 0.02 +0.0% reptile -0.8% +0.6% 0.01 0.02 +0.0% rewrite -0.8% +0.7% 0.02 0.02 +0.0% rfib -1.0% +0.4% 0.02 0.02 +0.0% rsa -0.7% +2.5% 0.02 0.02 +0.0% scc -0.1% +0.0% 0.00 0.00 +0.0% sched -0.8% +0.0% 0.01 0.02 +0.0% scs -1.9% +0.8% -5.3% -2.7% +0.0% simple -0.3% -0.0% 0.15 0.16 +6.9% solid -0.7% +0.0% 0.09 0.09 +0.0% sorting +0.0% +55.9% 0.00 0.00 +0.0% sphere -0.9% -1.8% 0.04 0.04 +0.0% symalg -0.8% +0.3% 0.01 0.01 +0.0% tak -0.8% +0.9% 0.01 0.01 +0.0% transform -0.8% +0.0% -3.3% -5.7% +0.0% treejoin +0.1% +109.3% 0.15 0.17 -7.4% typecheck -0.8% +0.0% 0.14 0.15 +0.0% veritas -0.8% +0.0% 0.00 0.00 +0.0% wang -0.9% +0.0% 0.07 0.08 +0.0% wave4main -0.8% +1.8% 0.18 0.19 -7.1% wheel-sieve1 -0.7% +0.0% +0.0% +1.5% -12.5% wheel-sieve2 -0.7% +0.0% 0.11 0.12 +2.1% x2n1 +7.4% +43.3% 0.01 0.01 +200.0% -------------------------------------------------------------------------------- Min -3.3% -4.0% -24.3% -18.4% -12.5% Max +7.4% +144.9% +77.6% +78.4% +200.0% Geometric Mean -0.5% +5.5% +1.8% +4.3% +3.2% I haven't had time to look through the regressions yet, so if someone has time, please grab a benchmark that looks bad and have a look at the Core to see what's going on. I suggest starting with "kahan", which is a relatively simple benchmark. -- Johan
