|
* parser is currently skipping tokens, (such as within #if

|

|
|
* The RETURN_TOKEN_NEVER_SKIP macro is a lower-level variant that
|
|
* makes the token returning unconditional. This is needed for things

|
* like #if and the tokens of its condition, (since these must be
|
|
* evaluated by the parser even when otherwise skipping).
|

* 1. If the skip stack is NULL, we are outside of all #if blocks
|
|
* and we are not skipping.
|

*
|

|
* the stack determines whether to skip. A type of
|
|
* SKIP_NO_SKIP is used for blocks wheere we are emitting
|
|
* tokens, (such as between #if 1 and #endif, or after the
|
|
* #else of an #if 0, etc.).
|
|
*
|
|
* 3. The lexing_directive bit overrides the skip stack. This bit
|
|
* is set when we are actively lexing the expression for a
|
|
* pre-processor condition, (such as #if, #elif, or #else). In
|
|
* this case, even if otherwise skipping, we need to emit the
|
|
* tokens for this condition so that the parser can evaluate
|
|
* the expression. (For, #else, there's no expression, but we
|
|
* emit tokens so the parser can generate a nice error message
|
|
* if there are any tokens here).
