This patch adds support for the new floating point vector elements (SF
and TF) introduced with arch12.
gcc/ChangeLog:
2017-03-24 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* config/s390/s390.c (s390_expand_vec_compare): Support other
vector floating point modes than just V2DF.
(s390_expand_vcond): Likewise.
(s390_hard_regno_mode_ok): Allow SFmode values in VRs.
(s390_cannot_change_mode_class): Prevent mode changes between TF
and V1TF in vector registers.
* config/s390/s390.md (DF, SF): New mode attributes.
("*cmp<mode>_ccs", "add<mode>3", "sub<mode>3", "mul<mode>3")
("fma<mode>4", "fms<mode>4", "div<mode>3", "*neg<mode>2"): Add
SFmode support for VRs.
* config/s390/vector.md (V_HW, V_HW2, VT_HW, ti*, nonvec): Add new
vector fp modes.
(VFT, VF_HW): New mode iterators.
(vw, sdx): New mode attributes.
