* Hexagon (target/hexagon) properly handle denorm in arch_sf_recip_commonTaylor Simpson2022-03-121-3/+3
| | | | | | | | | | | | | | | | The arch_sf_recip_common function was calling float32_getexp which adjusts for denorm, but the we actually need the raw exponent bits. This function is called from 3 instructions sfrecipa sffixupn sffixupd Test cases added to tests/tcg/hexagon/fpstuff.c Signed-off-by: Taylor Simpson <tsimpson@quicinc.com> Message-Id: <20220210021556.9217-6-tsimpson@quicinc.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
