I have done a few source to source asm compilers that include retaining
the original comments and sources.

What I did was rewrote the asm back-end to emit simple C statements and
then compiling these to the new target processor. For real life
applications it is an 85% solution. It gets the machine code correct for
the target processor but there are I/O code that is so architectural
specific that it needs to be hand translated.

The interesting part is the code transformation part works really well.
To the extent that generated code is often smaller because most C
compilers do very well with small statements and using C as an
intermediate form isolates most of the processor specific processor issues.
