[Qemu-devel] [PATCH 6/7] tcg: Streamline movcond_i64 using 32-bit arithmetic

2012-09-21 Thread Richard Henderson
Avoiding 64-bit arithmetic (outside of the compare) reduces the generated op count from 15 to 12, and the generated code size on i686 from 105 to 88 bytes. Signed-off-by: Richard Henderson --- tcg/tcg-op.h | 42 +++--- 1 file changed, 31 insertions(+), 11 dele
