Struct llvm_plugin::FunctionAnalysisManager

pub struct FunctionAnalysisManager { /* private fields */ }

Struct allowing to query the pass manager for the result of analyses on function IR.

Implementations

impl FunctionAnalysisManager

pub fn get_result<'a, A>(&self, function: &FunctionValue<'a>) -> &A::Resultwhere
    A: LlvmFunctionAnalysis,

Returns the result of the analysis on a given function IR.

If the result is not in cache, the pass manager will execute the analysis pass. Otherwise, the result is directly returned from cache.

Panics

Panics if the given analysis wasn’t registered (happens if the #[analysis] attribute wasn’t used), or if this function was called within the given analysis itself.

pub fn get_cached_result<'a, A>(
    &self,
    function: &FunctionValue<'a>
) -> Option<&A::Result>where
    A: LlvmFunctionAnalysis,

Returns the result of the analysis on a given function IR.

If the result is not in cache, None is returned. Otherwise, the result is directly returned from cache.

This function never triggers the execution of an analysis.

Panics

Panics if the given analysis wasn’t registered (happens if the #[analysis] attribute wasn’t used), or if this function was called within the given analysis itself.
