title: EngineBuilder (llvm.ee)

llvm.ee.EngineBuilder

A convenient class for building llvm.ee.ExecutionEngine. Each EngineBuilder instance can only create one ExecutionEngine.

Methods

create(self)

Create and return a new ExecutionEngine instance.

Raise llvm.LLVMException if the builder cannot create an ExecutionEngine base on the given configuration.

force_interpreter(self)

Force the output the output ExecutionEngine to be an LLVM IR interpreter.

force_jit(self)

Force the output the output ExecutionEngine to be a JIT engine.

opt(self, level)

Set the code generation optimization level for a JIT engine. Valid value of level is 0-3, inclusive. The default setting is 2. To use vector instructions, such as SSE on Intel processors, level must be 3 (aggressive).

Static Factory Methods

new(module)

Create a new EngineBuilder. module must be a llvm.core.Module instance. Its ownership is transferred to the resulting ExecutionEngine. Therefore, it is impossible to create more than one ExecutionEngine with a single EngineBuilder
