KVX pseudo relocation code to mark the end of the KVX
relocation enumerators that have direct mapping to ELF reloc codes.
There are a few more enumerators after this one; those are mainly
used by the KVX assembler for the internal fixup or to select
one of the above enumerators.

Dump the full list of instructions.
@cindex @samp{-march} option, KVX
@item -march=
The assembler supports the following architectures: kv3-1, kv3-2.
@cindex @samp{--check-resources} option, KVX
@item --check-resources
Check that each bundle does not use more resources than available. This is the
default.

Do not check that each bundle does not use more resources than available.
@cindex @samp{--generate-illegal-code} option, KVX
@item --generate-illegal-code
For debugging purposes only. In order to properly work, the bundle is sorted
with respect to the issues it uses. If this option is turned on the assembler
will not sort the bundle instructions and illegal bundles might be formed unless
they were properly sorted by hand.
@cindex @samp{--dump-table} option, KVX

This switch enables the register class "system register". This register
class is used when performing system validation and allows the full class of
system registers to be used even on instructions that are only valid with some
specific system registers.
