Detailed Description

"lldb/Expression/IRDynamicChecks.h" Encapsulates dynamic check functions used by expressions.

Each of the utility functions encapsulated in this class is responsible for validating some data that an expression is about to use. Examples are:

a = *b; // check that b is a valid pointer [b init]; // check that b is a valid object to send "init" to

The class installs each checker function into the target process and makes it available to IRDynamicChecks to use.

◆ DoCheckersExplainStop()

bool DynamicCheckerFunctions::DoCheckersExplainStop	(	lldb::addr_t	addr,
		Stream &	message
	)

Definition at line 78 of file IRDynamicChecks.cpp.

◆ Install()

bool DynamicCheckerFunctions::Install	(	DiagnosticManager &	diagnostic_manager,
		ExecutionContext &	exe_ctx
	)

Install the utility functions into a process.

This binds the instance of DynamicCheckerFunctions to that process.

Parameters

[in]	diagnostic_manager	A diagnostic manager to report errors to.
[in]	exe_ctx	The execution context to install the functions into.

Returns: True on success; false on failure, or if the functions have already been installed.
