/* 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. */
