           Summary: sizeof Gives Error When Used Inside an Inline Assembly
                    Block
           Product: D
           Version: 2.007
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3

Statement like "mov ECX,float.sizeof;" is not accepted by the compiler: Error:
"ptr expected".

Consider the following example (same example used also in issue # 1500):

         ========================================
         void asm_template(T)(T Tval,T* pDest)
         {
                 asm{
                         fld Tval;
                         mov EAX,pDest;
                         fstp T ptr[EAX];        //#1
                         fstp float ptr[EAX];    //#2
                         mov EDX,T.sizeof;       //#3 (this statement is ok!)
                         mov ECX,float.sizeof;   //#4 (ERROR: "ptr expected")
                 }//asm
         }//asm_template

         void main()
         {
           float f1=4.0;
           float f2=5.0;

           asm_template!(float)(f1,&f2);
         }
         ========================================
 Here is the compilation result of the 4 statements marked above:
 #1: ERROR: "cannot use type float as an operand" (issue # 1500)
 #2: OK
 #3: OK!!!
 #4: ERROR: "ptr expected" (this issue)

Normally statement # 4 should be accepted, as 'float.sizeof' should be
translated into the value '4'.

Workaround:

    alias float.sizeof FLOAT_SIZE;
    ...
    mov EAX,FLOAT_SIZE;
