Hi,
this patch adds expanders for fmin and fmax and the associated
cond and reduc ones. As per RISC-V V spec 1.0 vfmin/vfmax are
IEEE 754-2008 compliant so that should be ok.
Regards
Robin
gcc/ChangeLog:
* config/riscv/autovec.md (<ieee_fmaxmin_op><mode>3): fmax/fmin
expanders.
(cond_<ieee_fmaxmin_op><mode>): Ditto.
(cond_len_<ieee_fmaxmin_op><mode>): Ditto.
(reduc_fmax_scal_<mode>): Ditto.
(reduc_fmin_scal_<mode>): Ditto.
* config/riscv/riscv-v.cc (needs_fp_rounding): Add fmin/fmax.
* config/riscv/vector-iterators.md (fmin): New UNSPEC.
(UNSPEC_VFMIN): Ditto.
* config/riscv/vector.md (@pred_<ieee_fmaxmin_op><mode>): Add
UNSPEC insn patterns.
(@pred_<ieee_fmaxmin_op><mode>_scalar): Ditto.
