Ok. The way I envision this working from a user standpoint is -opt-bisect-limit <n> would mean "n applications of code transformatio...

...ream but saw this effort with pass execution instrumentation and thought it might fit there. Initially I think some very simple APIs in PassInstrumentationAnalysis would be fine, something like: // PIA - PassInstrumentationAnalysis if (PIA->skipTransformation()) { return; } // Do it. PIA->didTransformation(); This kind of interface also encourages good pass design like doing all the analysis for a transformation before actually doing the transformation. Some passes mix analysis with transformation and those are much harder to instrument to support -pass-max operation. In our implementation we...

Thanks Craig, that's exactly what I mean, stopping at particular changes inside a pass. Would you please refer me the discuss about combining opt-bisect with debug counters? Is it already under implementation? On Fri, Jun 8, 2018 at 12:19 AM Craig Topper <craig.topper at gmail.com> wrote: > I think that "level" was referring to what level of granularity the >
