--- Comment #2 from Marco Leise <marco.le...@gmx.de> 2012-08-15 01:06:15 PDT --- Since it all applies to FuncDeclaration::semantic3(...), I'll add this case: void b(Test t) nothrow { } struct Test { ~this() { throw new Exception("i am throwing"); } } The compiler checks for thrown exceptions or - more generally - the block exit state in two cases: 1) https://github.com/D-Programming-Language/dmd/blob/869d6dbffc4ab85576a39f19085ab7270ae2191e/src/func.c#L1301 2) https://github.com/D-Programming-Language/dmd/blob/869d6dbffc4ab85576a39f19085ab7270ae2191e/src/func.c#L1577 (2) handles the case of appending destructor calls for structs passed by value to a function. Functions without return/throw/etc. just get the destructors appended, while all others get them wrapped in a try-finally clause to ensure they are called. Since destructors may throw and the function isn't checked again after their addition, nothrow doesn't necessarily hold here. That's the case in the above example. (1) is the normal check if a function is nothrow, but throws. blockExit() determines the way any code block exits. This may be through 'return', 'throw', 'goto', halt (assert(0)?), 'break', 'continue' or the execution may unconditionally succeed or 'fall through'. That's my understanding anyways. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
