digitalmars.D.bugs - [Issue 13932] New: c++ mangling for template negative int parameter


          Issue ID: 13932
           Summary: c++ mangling for template negative int parameter
           Product: D
           Version: D2
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Keywords: link-failure
          Severity: normal
          Priority: P1
         Component: DMD
          Assignee: nobody puremagic.com
          Reporter: schveiguy yahoo.com

When linking with C++ code that uses a negative integer as a template
parameter, D will fail to link because it outputs e.g. '-1' instead of 'n1' as
required by ABI.



template <int x> struct S
    int member;

void func(S<-1> s) {}


struct S(int x)
    int member;

extern(C++) void func(S!(-1) s);

void main()


Undefined symbols for architecture x86_64:
  "__Z4func1SILi-1EE", referenced from:
      __Dmain in testcpp1.o

I don't know what platforms other than OSX this causes a problem on.

I am working on a pull that fixes this, will post soon.
