<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">But can you answer for some more questions?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">First of all, now LNT uses make-style of running tests and parse results from result csv file. Are there any plans to go to cmake?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">As I understood lit will run and collect all metrics, but there is no opportunity to make any settings for choosing what metrics I would like to collect. Test reports files
allow to choose what report I would like. One time I can use one, second time I can use another. I can do this with cmake only by changing test_modules in file.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">So I can’t group some metrics and give them some name.<o:p></o:p></span></p>

equal with report (simple) got with make. Cmake test-suite version has no features to run custom metrics and generate other report type, right?</span><o:p></o:p></p>

<p class="MsoNormal">The lit test-suite runner supports arbitrary metrics, it already features codesizes for different segments, compiletime, linktime, executable hash, execution time. I designed it be easily extensible with further metrics. Not all of these
metrics are understood by LNT yet so they may get lost after submission to an LNT database.<o:p></o:p></p>

<p class="MsoNormal">We do not use GenerateReport.pl and friends in the cmake/lit version anymore, as the main data collection and reporting mechanism in llvm has mostly shifted to LNT these days. In any case it should be easy to use “lit -o result.json” and
process the resulting json file in your favorite scripting language to generate arbitrary reports.<o:p></o:p></p>

<p class="MsoNormal">As far as the TEST.*.Makefile things go: Many of those variants have no equivalent in cmake/lit. But I have the strong feeling that the majority of those is not really used or even broken so there are no plans to adding them to. On the
other hand I would love to hear from people that actually use any of those besides TEST.simple.Makefile, it should be possible to transition most of them but I’d first like to hear what they are used for.<o:p></o:p></p>
