S390: Support new vector register sections
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15 include the existing 64-bit wide floating point registers. The Linux kernel presents the vector registers as two additional register sets, one for the right halves of v0-v15 and another one for the full registers v16-v31. Thus a new core file may contain two new register note sections, and this patch adds support to binutils for them. bfd/ * elf-bfd.h (elfcore_write_s390_vxrs_low): Add prototype. (elfcore_write_s390_vxrs_high): Likewise. * elf.c (elfcore_grok_s390_vxrs_low): New function. (elfcore_grok_s390_vxrs_high): New function. (elfcore_grok_note): Call them. (elfcore_write_s390_vxrs_low): New function. (elfcore_write_s390_vxrs_high): New function. (elfcore_write_register_note): Call them. binutils/ * readelf.c (get_note_type): Add NT_S390_VXRS_LOW and NT_S390_VXRS_HIGH. include/elf/ * common.h (NT_S390_VXRS_LOW): New macro. (NT_S390_VXRS_HIGH): Likewise.
