Hi Daniel!

You could try the integrated LLVM assembler. I am currently 
testing this setup.

1. In driver/toobj.cpp, set bool const assembleExternally = false;
2. in std.math, exchange in real poly(...) the inline assembler 
with the D version (simply replace D_InlineAsm_X86 with none).

This is what I am currently testing.
