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
