Recognize S/390 targets with the new vector feature and present their vector registers appropriately: as 32 new 128-bit wide registers v0-v31, where the first 16 embed the floating point registers f0-f15. Each of the full registers v0-v15 is modelled as a pseudo register. gdb/ChangeLog: * s390-linux-nat.c (have_regset_vxrs): New static variable. (s390_linux_fetch_inferior_registers): Handle vector registers, if present. (s390_linux_store_inferior_registers): Likewise. (s390_get_hwcap): Remove function. Embed its logic... (s390_read_description): ...here. Yield a target description with vector registers if applicable. * s390-linux-tdep.c: Include "features/s390-vx-linux64.c", "features/s390-tevx-linux64.c", "features/s390x-vx-linux64.c", and "features/s390x-tevx-linux64.c". (struct gdbarch_tdep) <v0_full_regnum>: New field. (s390_dwarf_regmap): Add vector registers. Remove bogus entries for "GNU/Linux-specific registers". (s390_dwarf_reg_r0l): New enum value. (s390_dwarf_reg_to_regnum): Support vector registers. (s390_adjust_frame_regnum): Adjust pseudo DWARF register numbers of GPR lower halves. (regnum_is_vxr_full): New function. (s390_register_name): New function. (s390_pseudo_register_name): Handle v0-v15, which are composed of f0-f15 and v0l-v15l. (s390_pseudo_register_type): Likewise. (s390_pseudo_register_read): Likewise. (s390_pseudo_register_write): Likewise. (s390_value_from_register): Account for the fact that values are placed left-justified in vector registers. (s390_pseudo_register_reggroup_p): Add pseudo registers v0-v15 to the vector reggroup and omit them from the general reggroup. (s390_regmap_vxrs_low, s390_regmap_vxrs_high): New register maps. (s390_vxrs_low_regset, s390_vxrs_high_regset): New regsets. (s390_iterate_over_regset_sections): Add iterations for the two new vector regsets. (s390_core_read_description): Yield a target description with vector registers if applicable. (s390_gdbarch_init): Handle target descriptions with vector registers. Add "register_name" gdbarch method. (_initialize_s390_tdep): Call new tdesc initialization functions. * s390-linux-tdep.h (HWCAP_S390_VX): New macro. (S390_V0_LOWER_REGNUM, S390_V1_LOWER_REGNUM, S390_V2_LOWER_REGNUM) (S390_V3_LOWER_REGNUM, S390_V4_LOWER_REGNUM, S390_V5_LOWER_REGNUM) (S390_V6_LOWER_REGNUM, S390_V7_LOWER_REGNUM, S390_V8_LOWER_REGNUM) (S390_V9_LOWER_REGNUM, S390_V10_LOWER_REGNUM) (S390_V11_LOWER_REGNUM, S390_V12_LOWER_REGNUM) (S390_V13_LOWER_REGNUM, S390_V14_LOWER_REGNUM) (S390_V15_LOWER_REGNUM, S390_V16_REGNUM, S390_V17_REGNUM) (S390_V18_REGNUM, S390_V19_REGNUM, S390_V20_REGNUM) (S390_V21_REGNUM, S390_V22_REGNUM, S390_V23_REGNUM) (S390_V24_REGNUM, S390_V25_REGNUM, S390_V26_REGNUM) (S390_V27_REGNUM, S390_V28_REGNUM, S390_V29_REGNUM) (S390_V30_REGNUM, S390_V31_REGNUM): New macros.
