Hexagon (target/hexagon) Change subtract from zero to change sign
The F2_sffms instruction [r0 -= sfmpy(r1, r2)] doesn't properly handle -0. Previously we would negate the input operand by subtracting from zero. Instead, we negate by changing the sign bit. Test case added to tests/tcg/hexagon/fpstuff.c Signed-off-by: Taylor Simpson <tsimpson@quicinc.com> Reviewed-by: Anton Johansson <anjo@rev.ng> Message-Id: <20230307025828.1612809-12-tsimpson@quicinc.com>
