For GCC/Clang you'd want -S
I know about that, but take a look at it:

Contrast with what -vasm does:

int fred(int* a)
{
return a[11];

-vasm gives me what I want to see. There aren't extra steps to getting it, the
object code is included, and all the boilerplate is omitted.
It's all about the friction.
