Ok, so you would go without a function-like API.

I think you're missing a few parameters here, like the ASM dialect (intel vs
ATT) unless that would be the string ".intel_syntax;" at the start of the
asm_template. Also, the parameter location might be missing.

Does gcc provide a way to specify whether the stack should be aligned properly,
or is it done automatically, or should it be specified manually in asm_template
with a string like ".align 32"?
