Function Documentation

void vm_add_jit

(

JIT *

jit

)

void vm_delete_all_jits

(

)

void compile_protect_arguments	(	Method_Handle	method,
		GcFrame *	gc
	)

Protect arguments from GC.

The arguments are those passed to the last M2nFrame. The given method's signature describes what arguments were passed.

void compile_flush_generated_code_block	(	Byte *	,
		size_t
	)

Code has been generated by writing it to memory.

Ensure that it is visible to all instruction fetchers. The first function flushes a particular block of code, another should be called after all blocks are flushed.

void compile_flush_generated_code

(

)

JIT_Result compile_do_compilation_jit	(	Method *	method,
		JIT *	jit
	)

Execution manager uses this method to call back to VM to compile a method using a specific JIT.

NativeCodePtr compile_gen_compile_me

(

Method_Handle

method

)

Generate a stub in JIT calling convention to pass call compile_me() on the first method invocation.

NativeCodePtr compile_me

(

Method *

method

)

A function to call on the first method invocation.

Returns:

an entry point of successfully compiled method

Exceptions:

an

exception otherwise

void patch_code_with_threads_suspended	(	Byte *	code_block,
		Byte *	new_code,
		size_t	size
	)

Global_Env* compile_handle_to_environment

(

Compile_Handle

)

NativeCodePtr compile_create_lil_jni_stub	(	Method_Handle	method,
		void *	func,
		NativeStubOverride	nso
	)

Create a LIL stub for JNI interfacing.

NativeCodePtr interpreter_compile_create_lil_jni_stub	(	Method_Handle	method,
		void *	func,
		NativeStubOverride	nso
	)

Create a LIL stub for JNI interfacing.

NativeCodePtr compile_create_lil_pinvoke_stub	(	Method_Handle	method,
		void *	func,
		NativeStubOverride	nso
	)

Create a LIL stub for PINVOKE interfacing.

bool needs_override

(

Method *

)

NativeCodePtr compile_do_instrumentation	(	CodeChunkInfo *	callee,
		MethodInstrumentationProc	instr_proc
	)

Interpose on calls to the specified method by calling the instr_proc.

void count_method_calls

(

CodeChunkInfo *

callee

)

A MethodInstrumentationProc that records the number of calls from the caller code chunk to the callee.

DynamicCode* compile_get_dynamic_code_list

(

void

)

Adding dynamic generated code info to global list.

Is used in JVMTI and native frames interface
