How to update SystemZ tables.

• Checkout LLVM. Patches are tested on commit c13d5969^, because c13d5969 changed the decode table format.
• Apply patches from the current directory.
• Run tablegen.

      cd $LLVM
      mkdir build
      cd build
      cmake -DCMAKE_CXX_FLAGS=-DCAPSTONE ..
      make SystemZCommonTableGen -j$(getconf _NPROCESSORS_ONLN)
  

• Copy .inc files.

      cp arch/SystemZ/SystemZGenInsnNameMaps.inc \
         arch/SystemZ/SystemZGenInsnNameMaps.inc.old
      for inc in $(cd arch/SystemZ && ls *.inc); do
        cp $LLVM/build/lib/Target/SystemZ/$inc arch/SystemZ/
      done
  

• Fixup SystemZGenInsnNameMaps.inc.

      comm -1 -3 \
          <(grep SYSZ_INS_ <arch/SystemZ/SystemZGenInsnNameMaps.inc.old \
            | sort -u) \
          <(grep SYSZ_INS_ <arch/SystemZ/SystemZGenInsnNameMaps.inc \
            | sort -u) \
          >arch/SystemZ/SystemZGenInsnNameMaps.inc.new
      cat arch/SystemZ/SystemZGenInsnNameMaps.inc.old \
          arch/SystemZ/SystemZGenInsnNameMaps.inc.new \
          >arch/SystemZ/SystemZGenInsnNameMaps.inc
  

• Add new groups, insns, registers and formats.
  • include/capstone/systemz.h
    • enum sysz_insn:

          comm -1 -3 \
              <(perl -ne 'if (/(SYSZ_INS_.+),/) { print "\t$1,\n" }' \
                <include/capstone/systemz.h | sort -u) \
              <(perl -ne 'if (/(SYSZ_INS_.+),/) { print "\t$1,\n" }' \
                <arch/SystemZ/SystemZMappingInsn.inc | sort -u)
      

    • enum sysz_insn_group:

          perl -ne 'if (/(SYSZ_GRP_.*?),/) { print "\t$1,\n"; }' < \
              arch/SystemZ/SystemZMappingInsn.inc | sort -u
      

  • arch/SystemZ/SystemZDisassembler.c
  • arch/SystemZ/SystemZInstPrinter.c
  • arch/SystemZ/SystemZMCTargetDesc.c
  • arch/SystemZ/SystemZMCTargetDesc.h
  • arch/SystemZ/SystemZMapping.c
    • enum group_name_maps:

          perl -ne 'if (/(SYSZ_GRP_(.*?)),/) { print "\t{ $1, \"" . lc($2) . "\" },\n"; }' \
              arch/SystemZ/SystemZMappingInsn.inc | sort -u
