It can also be used - to test the parity flag, using bit 0 of the population count. - - Do not do this for target_ulong-sized values however; the optimizer would - produce a comparison against zero anyway, and it avoids shifts by 64 - which are undefined behavior. - - Reviewed-by: Richard Henderson <richard.henderson@linaro.org> - Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> - - target/i386/tcg/translate.c | 28 ++++++++++++++++++++-------- - target/i386/tcg/emit.c.inc | 5 ++--- - 2 files changed, 22 insertions(+), 11 deletions(-) -bisect found first bad commitâ -```""" |
