<p class="MsoNormal" style="margin-bottom:12.0pt">I would *really* love to see this feature available -- writing in a combination of C and inline assembler is still quite common in embedded software development. Verbose asm would be a very useful tool in debugging.<o:p></o:p></p>
</div>
<p class="MsoNormal">...speaking on inline assembler, I wonder how your implementation works with it? Does it simply print a whole inline assembly statement (from C source code) before printing it again (from generated assembler)?<br>
<br>
> For clang it would simply mean to add a flag like -fsource-asm or maybe extend the meaning of -fverbose-asm (like it will happen in GCC 7 but see some further comments below).<o:p></o:p></p>

</div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I vote for the latter. GCC is still most commonly used compiler in embedded development (for which generating assembler file is most relevant) -- the closer we are to it, the better for everyone.<o:p></o:p></p>
