I doubt that records larger than say 4 register widths are ever passed by-value. But I definitely can't exclude it, cause I don't know every ABI of every platform by heart. So if you want details there then study the ABIs of the platforms you use.
I doubt that any ABI would say something about Pascal "const" rather than C "const". So, that argument doesn't hold. The only reason I can possibly think of (for "const" to pass large parameters by value and thus violating the rule that "const" chooses the most efficient method) is compatibility with Delphi in delphi compiler mode. If that's true, which I don't know, it should be documented. Otherwise, "const" will continue to puzzle programmers - and in a year we will have the same discussion again.
