Struct TargetOptionMap 

pub struct TargetOptionMap { /* private fields */ }

What #pragma GCC target asked for, at every point of the token list.

GCC’s directive applies to the functions defined after it, so the answer depends on where in the stream the definition stands — exactly as PackMap’s does for a struct. An empty list is the usual answer: the map is empty unless the unit wrote the directive at all.

Implementations

impl TargetOptionMap

pub fn new(events: Vec<(usize, Vec<(String, SourceRange)>)>) -> Self

Builds the map from the preprocessor’s events, which are in order.

pub fn is_empty(&self) -> bool

Whether any #pragma GCC target was written at all.

pub fn at(&self, index: usize) -> &[(String, SourceRange)]

The instruction sets in force at token index.
