Add support for vmdump 64big format to the zgetdump utility. The result is an elf file suitable for tool crash. This patch adds file dfi_vmdump.c to handle conversion from z/VM vmdump format to the internal memory representation of this tool. Therefore both output formats elf and s390 are supported as target of the conversion. The vmdump file formats 32bit and 64bit are not supported anymore. They have been obsolete since CP version 5.1 (end of service since 30-Sep-2009). Vector register set is not part of a vmdump file and can not be displayed. Output before: # zgetdump ~/vmdump-0383 zgetdump: No valid dump found on "/root/vmdump-0383" # Output after: # ./zgetdump ~/vmdump-0383 ~/vmdump-0383.elf Format Info: Source: vmdump Target: elf Copying dump: 00000000 / 00000379 MB 00000379 / 00000379 MB Success: Dump has been copied # file ~/vmdump-0383.elf /root/vmdump-0383.elf: ELF 64-bit MSB core file, IBM S/390, version 1 \ ....
