That is not a bad idea. Note for inlining, GCC does have already the inline
keyword which allows to ignore the computed size when it comes to inlining and
consider the inline-asm as 0.

That already is handled by the inline keyword.
so `__asm inline("" : "+r" (var));`
Yes it is documented:
https://gcc.gnu.org/onlinedocs/gcc-14.2.0/gcc/Size-of-an-asm.html
The inline keyword was added in GCC 9 though not documented on the changes
page.
