Just a small thought...

Why not provide interfaces to _ANY_ assembler (as86, gas, masm, tasm)
defined in some sort of "compiler inline assembler section configuration
file" ;)

-> assemblers.conf:

  <assembler id="masm">
    <exec>c:\masm\bin\ml.exe</exec>
    <param>-c</param>
  </assembler>

-> test.d:

  .
  .
  .

  version(X86) {
    asm(masm) {
      ...
    }
  }
  version(SparcIII) {
    asm(gas) {
      ...
    }
  }
  else
  {
    ...
  }

  .
  .
  .


Benefits:

-> Inline assembly code easier to port
-> Cutting-edge opcodes are always supported using latest assembler versions
(e.g. Intel's SSE)

That would require the D compiler to emit assembler source for everything
else, for feeding to the assembler. It's less work to just build the
assembler right into the compiler, and the result is much faster
compilation, and no bugs due to mismatched assembler/compiler combinations.

I think, rather than do that, asm() should accept the CPU type, and can
either use an internal assembler or whatever is available for that arch.
