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
