Summary: Template attribute inferrence doesn't work Product: D Version: unspecified Platform: All OS/Version: All Status: NEW Severity: critical Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: jmdavisp...@gmx.com --- Comment #0 from Jonathan M Davis <jmdavisp...@gmx.com> 2012-08-03 21:28:45 PDT --- This code import std.stdio; import std.traits; void func(R)(R range) { } void main() { pragma(msg, mangledName!(func!string)); static assert(functionAttributes!(func!string) == FunctionAttribute.safe); } results in this output _D1y13__T4funcTAyaZ4funcFAyaZv y.d(11): Error: static assert (0u == cast(FunctionAttribute)1u) is false func is templatized and has _nothing_ in it, so it should be inferred as @safe, pure, and nothrow, but as evidenced by the name mangling and complete lack of function attributes, it has been marked with none of those. The fact that this _really_ basic function isn't inferring any attributes makes it seem likely that attributes aren't ever getting inferred for any functions. Certainly, nothing I've tried thus far has resulted in any attributes being inferred (including adding @safe function calls to func, so it's not related to the fact that func is empty). And this code didn't work in the version of dmd when attribute inferrence was supposedly introduced (2.054) - or any version since then - so I have no idea what attribute inferrence is supposedly going on, since it's clearly not working. This is probably the same as bug# 8138, since that's specifically for attribute inferrence and Voldemort types, but if attribute inferrence isn't working for templates at all, then it's certainly not going to work for Voldemort types. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
