Hi Sylvestre,, * Sylvestre Ledru <[email protected]> [2022-08-19 23:46]:
Could you please provide a reduce test case?
Sure, this produces the same error with clang++-14 on armel but works with
clang++-13 and gcc:
template <typename Packet> void psincos_float(Packet &_x) {
__asm__("" : "+g,w"(_x));
}
int main() {}
Some context to the function is here:

Cheers Jochen
