示例1: must_be_compiled
// Returns true if m must be compiled before executing it
// This is intended to force compiles for methods (usually for
// debugging) that would otherwise be interpreted for some reason.
bool CompilationPolicy::must_be_compiled(methodHandle m, int comp_level) {
if (m->has_compiled_code()) return false; // already compiled
if (!can_be_compiled(m, comp_level)) return false;
return !UseInterpreter || // must compile all methods
(UseCompiler && AlwaysCompileLoopMethods && m->has_loops() && CompileBroker::should_compile_new_jobs()); // eagerly compile loop methods
}示例2: mustBeCompiled
// Returns true if m must be compiled before executing it
// This is intended to force compiles for methods (usually for
// debugging) that would otherwise be interpreted for some reason.
bool CompilationPolicy::mustBeCompiled(methodHandle m) {
if (m->has_compiled_code()) return false; // already compiled
if (!canBeCompiled(m)) return false;
return !UseInterpreter || // must compile all methods
(UseCompiler && AlwaysCompileLoopMethods && m->has_loops()); // eagerly compile loop methods
}示例3: compile
// Check if the method can be compiled, change level if necessary
