I have a basic question. I want to compare 2 clang binaries one with a patch and one without patch for performance.
I went though http://llvm.org/docs/lnt/quickstart.html and and followed the steps to generate the reports for both the binaries but i was unable to compare the 2 results. Upon seeing the options under-
ln runtest nt --help it seems i need to set cc as clang with patch and cc-reference and clang without patch.
I tried the following command -
lnt runtest nt
but this gave me an error as follows-
“lnt: error: --cc-reference is unused with --simple” .
Could someone please let me know the correct approach and command to compare reports generated for 2 clang binaries(1 with patch/changes and other as base revision).
Thanks for the help.
