+/* 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.  */
