Bug 1614 – sizeof Gives Error When Used Inside an Inline Assembly Block

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;
