Sorry, somewhat of a tangent but regarding:
> The %0 and %1 are positional references into a list you have to count by hand.
You can name your operands in gcc inline assembly.
https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#Output-...
Look for "asmSymbolicName".
On a phone so not checking if it builds, but something like `asm("add %[my_out], %[my_in], #3":[my_out]"=r"(outvar):[my_in]"r"(invar):);`.
The equivalent Odin syntax looks like this:
add_three :: asm(my_in: u64) -> (my_out: u64) { add my_out, my_in, 3 }
out_var = add_three(in_var)
Which is already infinitely more readable and requires no parochial sigils nor the arcane clobbering syntax.
The parent was objecting to the syntax allegedly forcing one to use “positional references into a list you have to count by hand”. Being inaccurate in your criticism just makes it appear questionable as a whole.
