DMD goes from its own backend block tree to an object file, 
without writing assembly. In fact, only recently was the ability 
to output asm added for debugging purposes:

On Linux dmd invokes gcc by default to create an executable, but 
only to link the resulting object files, not to compile 
C/assembly code.

LDC goes from LLVM IR to machine code, but it can output assembly 
with the `-output-s` flag.

GDC does generate assembly text to the tmp folder and then 
invokes `gas` the GNU assembler, it can't directly write machine 
code.
