2024-12-24target/hexagon: Simplify internal_mpyhh setupRichard Henderson1-1/+1
Initialize x with accumulated via direct assignment, rather than multiplying by 1. Reviewed-by: Brian Cain <brian.cain@oss.qualcomm.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-12-24target/hexagon: Use mulu64 for int128_mul_6464Richard Henderson1-29/+3
No need to open-code 64x64->128-bit multiplication. Reviewed-by: Brian Cain <brian.cain@oss.qualcomm.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-12-24target/hexagon: Remove DoubleRichard Henderson1-31/+17
This structure, with bitfields, is incorrect for big-endian. Use extract64 and deposit64 instead. Reviewed-by: Brian Cain <brian.cain@oss.qualcomm.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-12-24target/hexagon: Remove FloatRichard Henderson1-13/+3
This structure, with bitfields, is incorrect for big-endian. Use the existing float32_getexp_raw which uses extract32. Reviewed-by: Brian Cain <brian.cain@oss.qualcomm.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-12-24target/hexagon: Expand GEN_XF_ROUNDRichard Henderson1-128/+127

2024-12-24target/hexagon: Use float32_muladd for helper_sffm[as]_libRichard Henderson1-79/+26
There are multiple special cases for this instruction. (1) The saturate to normal maximum instead of overflow to infinity is handled by the new float_round_nearest_even_max rounding mode. (2) The 0 * n + c special case is handled by the new float_muladd_suppress_add_product_zero flag. (3) The Inf - Inf -> 0 special case can be detected after the fact by examining float_flag_invalid_isi.

2024-12-24target/hexagon: Use float32_muladd_scalbn for helper_sffma_scRichard Henderson1-8/+3
This instruction has a special case that 0 * x + c returns c without the normal sign folding that comes with 0 + -0. Use the new float_muladd_suppress_add_product_zero to describe this.

2024-12-24target/hexagon: Use float32_muladd for helper_sffmsRichard Henderson1-3/+2
There are no special cases for this instruction. Since hexagon always uses default-nan mode, explicitly negating the first input is unnecessary. Use float_muladd_negate_product instead.
