llvm::instrumentor::InstrumentationConfig

Synopsis

Declared in <llvm/Transforms/IPO/Instrumentor.h>

struct InstrumentationConfig;

Description

It holds the information for each instrumented opportunity, including the base configuration options. Another class may inherit from this one to modify the default behavior.

Member Functions

Name	Description
`InstrumentationConfig` [constructor]	Construct an instrumentation configuration with the base options.
`~InstrumentationConfig` [destructor] [virtual]	Destroy the instrumentation configuration.
`addBaseChoice`	Add a base configuration option into the list of base options.
`addChoice`	Register an instrumentation opportunity.
`getBasePointerInfo`	Return the base pointer info for a value.
`getGlobalString`	Return a global string constant for `S,` creating it if needed.
`getRTName`	`getRTName` overloads
`init`	Initialize the config to a clean base state without losing cached values.
`populate` [virtual]	Populate the instrumentation opportunities.

Static Member Functions

Name	Description
`allocate`	Allocate an object of type `Ty` using a bump allocator.
