31 /* There are a number of different formats used for local labels. gas
32 expects local labels either of the form `10$:' or `n:', where n is
33 a single digit. When LOCAL_LABEL_DOLLARS is defined labels of the
34 form `10$:' are expected. When LOCAL_LABEL_FB is defined labels of
35 the form `n:' are expected. The latter are expected to be referred
36 to using `nf' for a forward reference of `nb' for a backward
39 The local labels expected by the TI tools are of the form `$n:',
40 where the colon is optional. Now the $ character is considered to
41 be valid symbol name character, so gas doesn't recognise our local
42 symbols by default. Defining LEX_DOLLAR to be 1 means that gas
43 won't allow labels starting with $ and thus the hook
44 tc_unrecognized_line() will be called from read.c. We can thus
45 parse lines starting with $n as having local labels.
47 The other problem is the forward reference of local labels. If a
48 symbol is undefined, symbol_make() calls the md_undefined_symbol()
49 hook where we create a local label if recognised. */
