           Summary: No const folding on asm db,dw, etc
           Product: D
           Version: 0.177
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: clugdbug at yahoo.com.au


This code generates the error message "const init" which doesn't make much
sense.
(The "goto end" is only included to make it safe to run).
The same bug applies also to dd, ds, di, dl, de, df
(and to dw, dq, and dt, which are undocumented).
-------
void main()
{
    goto end;
    const byte z = 35;
    asm { db z; }
    end: ;
}
-------
And it would be nice if 
asm { db 1+2; } 
also worked (it currently prints "end of instruction").
