crypto: x86/poly1305 - emit does base conversion itself (f9e7fe32) · Commits · 戴 / test

The emit code does optional base conversion itself in assembly, so we don't need to do that here. Also, neither one of these functions uses simd instructions, so checking for that doesn't make sense either. Signed-off-by:
