Call graph

This allows to:

• detect dead cycles
• detect dead transitive calls

thanks for working on making dead-code detection even better.

in case you are interessted in edge-cases in which dead code is detected, but might be a false-positive, I would suggest running this tool on phpunit :)

• git clone phpunit
• add to phpstan.neon:

includes:
    - vendor/shipmonk/dead-code-detector/rules.neon 

• run php tools/phpstan

-> 493 errors reported :)

Thanks, first run is often tricky.

It gave hundreds of errors for phpstan-src too, but with a single @api provider, it came down to ~50 valid reports: phpstan/phpstan-src#3581 And even there, I did not find a single false-positive. Mostly, those are tricky magic things like dealing with DIC (which is really really hard to support properly, so I disabled __construct analysis there).
