templates and assembler

[manu]

Hi there!
I´m new to D and quite surprised about all the nice features it provides. So I
started to write some test apps and also tried to write some templates. It all
worked perfect until I wanted to use template identifiers in asm blocks.

consider the following:

/* file - main.d **************************************/
01: template sine(REAL) // where REAL should be one of float,double,real 
02: {
03:     float sine(REAL x)
04:	{
05:	    asm 
06:	    {
07:	        naked		    ; // <- make it naked to get maximum speed
08:		fld REAL ptr[ESP+4] ; // <- critical opcode
09:		fsin		    ;
10:		ret		    ;
11:	    }
12:     }
13: }
14: alias sine!(float) sine_float; // instantiation
/ *****************************************************/
An error occurs when typing the last line, due to the instantiation. It says:

main.d(8): end of instruction

I´ve figured out that it comes because of the REAL in the asm block. I also
tried this for line 08:

08:   fld x

Though this compiles there remains an error at runtime: the program assumes x to
be at a different position on the stack and so just a dump of stack memory is
loaded into the FPU. May this an unfixed bug of the compiler(I´m using dmd)? 

I would be very thankful to everybody who helps me fixing that problem!
