--- Comment #2 from David <gccbugzilla at limegreensocks dot com> ---
In fact, this effect of '+' is explicitly documented at
<https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#OutputOperands>:
Operands using the '+' constraint modifier count as two operands (that is, both
as input and output) towards the total maximum of 30 operands per asm
statement.
Have you actually hit this limit? Or is this a theoretical discussion?
