However, GCC shows that - it can be done branchless in the ASM (as we do for FLOAT_ABS, which is easier - because it has an explicit sign bit). GCC generates: - - movq %rdi, %rdx - sarq $63, %rdx - movq %rdx, %rax - xorq %rdi, %rax - subq %rdx, %rax - ret - - ConstantFloat(0.0) should be generated with pxor %xmm, %xmm; instead of a movabs. _______________________________________________ pypy-commit mailing list pypy-commit@python.org http://mail.python.org/mailman/listinfo/pypy-commit
