[LLVMdev] LNT usage

Mon Mar 11 14:44:45 PDT 2013

:)

Done that several times --- and even went in the lnt source code --- but I 
missed the '--multisample' each time. That's probably what I need.

Thanks Michael,

2. Running lnt several times on the same unmodified clang+llvm binaries gives 
different results (execution time can vary wildly : ~200%). I am running lnt 
on linux/x86_64. I tried to deactivate the cpufreq thing, the machine was not 
loaded, but this did not change. Is there any way to run the tests multiple 
times and use statistics to get reproducible numbers (within a confidence 
interval) ? Or to handle the stats at the 'lnt import' stage ? Or in the web 
display ? In the web display, how to use the 'run' and 'order' fields ?

Run "lnt runtest nt --help". = ).

Michael

Thanks for any hint.
