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