/* There are a number of different formats used for local labels.  gas

   expects local labels either of the form `10$:' or `n:', where n is

   a single digit.  When LOCAL_LABEL_DOLLARS is defined labels of the

   form `10$:' are expected.  When LOCAL_LABEL_FB is defined labels of

   the form `n:' are expected.  The latter are expected to be referred

   to using `nf' for a forward reference of `nb' for a backward

   reference.

   The local labels expected by the TI tools are of the form `$n:',

   where the colon is optional.  Now the $ character is considered to

   be valid symbol name character, so gas doesn't recognise our local

   symbols by default.  Defining LEX_DOLLAR to be 1 means that gas

   won't allow labels starting with $ and thus the hook

   tc_unrecognized_line() will be called from read.c.  We can thus

   parse lines starting with $n as having local labels.

   The other problem is the forward reference of local labels.  If a

   symbol is undefined, symbol_make() calls the md_undefined_symbol()

   hook where we create a local label if recognised.  */
