Revision 70c48285


Added by Richard Henderson almost 14 years ago

target-sparc: Inline some generation of carry for ADDX/SUBX.

Computing carry is trivial for some inputs. By avoiding an
external function call, we generate near-optimal code for
the common cases of add+addx (double-word arithmetic) and
cmp+addx (a setcc pattern).
