| /* 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. */ |
