Interestingly, this - is not a particularly effective optimization on its own, though it avoids - the cost of correct RF emulation that was added in the previous patch. - The main benefit lies in allowing the hoisting of loop invariants outside - the loop, which will happen separately. - - The loop exits when the low 16 bits of CX/ECX/RCX are zero (so generally - speaking the string operation runs in 65536 iteration batches) to give - the main loop an opportunity to pick up interrupts. - - Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> - Reviewed-by: Richard Henderson <richard.henderson@linaro.org> - Link: https://lore.kernel.org/r/20241215090613.89588-12-pbonzini@redhat.com - Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> - - target/i386/tcg/translate.c | 55 ++++++++++++++++++++++++++++++++++++++++----- - 1 file changed, 49 insertions(+), 6 deletions(-) -```""" |
