...n for each benchmark). If you could modify the benchmark programs to default to the sizes you specified, and send me the diff, I would be happy to apply it. :) -Chris > here goes output (which shows that llvm is already > better for test with intensive function calls): > > time -p ./gcc_ackermann 11 > user 2.36 > time -p ./llvm_ackermann 11 > user 1.07 > > ---- > time -p ./gcc_ary3 300000 > user 2.86 > time -p ./llvm_ary3 300000 > user 3.19 > > ---- > time -p ./gcc_fib2 39 > user 2.32 > time -p ./llvm_fib2 39 > user 1.61 > > ---- > time...

Hi devels, there are two issues concerning invoking optimizations: 1. this document: http://llvm.cs.uiuc.edu/docs/GettingStarted.html is very nice, it would be good though to add in a section An Example Using the LLVM Tool Chain examples on optimization step. 2. If i am not wrong there is no tool, which integrates all steps: llvmgcc->opt->llc into something like llcc (and
