I hope I have the transformed syntax correct. I always write with 
GDC and always use variable names, but I don’t have much 
experience at all.

Here’s a test run:

0237: Module Test::
source:
asm=[asm @safe pure nothrow nogc
                                 {
                                 .intel_syntax

                                 add %[ p1 ], %[ p2 ]
                                 mov %[ p3 ], %[ p1 ]

                                 .att_syntax

                         : /* output */
                                 [ p1 ]  "+r"    ( sum ),
                                 [ p3 ]  "=r"    ( dest )
                         : /* input */
                                 [ p2 ]  "rm"    ( plus )
                         : /* clobbers */
                         ;
                         }
                         ]
result=[asm @safe pure nothrow nogc
                                 {
                                 .intel_syntax

                                 add %0, %2
                                 mov %1, %0

                                 .att_syntax

                         : /* output */
                                         "+r"    ( sum ),
                                         "=r"    ( dest )
                         : /* input */
                                         "rm"    ( plus )
                         : /* clobbers */
                         ;
                         }
                         ];
