http://d.puremagic.com/issues/show_bug.cgi?id=9292 Summary: hasNestedArgs wrong result for nested template literal Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: johannespfau gmail.com PST --- Created an attachment (id=1178) test case When compiling testcase.d, hasNestedArgs returns these results: topNIndex!() nested=0 Test!(indirectLess) nested=1 BinaryHeap!(Test()) nested=0 AFAIK BinaryHeap!(Test()) should also be marked as nested, as it needs Test!(indirectLess) which is nested? I'm not sure if this causes a real problem in dmd, but we use hasNestedArgs/isnested in gdc to tell the backend if the instantiated template is accessible from other modules. Therefore this test case currently ICEs gdc (also depends on gcc version. Some are more picky) BTW: Would it be OK to mark this as "blocker", as it blocks gdc from compiling that test case? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I think I've had this argument before with Alex over whether I should follow suit or carry on marking nested functions as non-public. Call by alias is meant to be a direct call that skips any checks for where the function actually is. So far have been special casing these instances as I find them. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=9292 PST --- What drawback has marking all functions PUBLIC? I guess it'll completely prevent the backend from removing unreachable nested functions so it's not a perfect soultion. Although it sounds like a simple & quick solution to a not so simple problem. Doesn't detecting such cases in the backend basically mean duplicating the hasNestedArgs functionality? And I guess the GCC backend doesn't let us skip those tests, as it seems to chocke on nested, public functions. We can continue the gdc specific discussion here: http://gdcproject.org/bugzilla/show_bug.cgi?id=35 but I think we should still leave this bug open as it's also a bug in the frontend. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
