Extra assertions for mutators and epilogues #1182

Closed wks closed 3 months ago

wks commented 3 months ago

This commit adds assertions about the number of mutators and the list of mutators returned from the VM binding.

Also asserts that epilogues are not silently dropped before they are executed. It could happen if a buggy VM binding returns a number of mutators that does not match the actual list of mutators.

This should detect bugs like https://github.com/mmtk/mmtk-ruby/issues/84
