However, a thinko in the expansion of svsudot meant that the arguments weren't in fact swapped; the attempted swap was just a no-op. And the testcases blithely accepted that. gcc/ PR target/114607 * config/aarch64/aarch64-sve-builtins-base.cc (svusdot_impl::expand): Fix botched attempt to swap the operands for svsudot. gcc/testsuite/ PR target/114607 * gcc.target/aarch64/sve/acle/asm/sudot_s32.c: New test. (cherry picked from commit 2c1c2485a4b1aca746ac693041e51ea6da5c64ca)
