--- Comment #6 from Yichao Yu <yyc1992 at gmail dot com> --- > For aarch64, there was talk about adding stp for q registers. What do you mean? I was initially unsure about it too but I assume it already exist since clang (and now GCC 9) emits it and the arm arch reference manual also mentions it without mentioning it only available in a later version.
