What returns Assembler.make()?

What returns Assembler.make()?

 

That is bytes of opcodes?

 

If right, how can I get that bytes length?

 

 

Is it automately allocate virtual memory?

 

If yes, can I get assembled codes in stack or heap whitout allocation?

 

 

Thanks.

Whoa...one question at a time!

1. Do you mean what Assembler.make() returns? Cause it's the built function. Calling the function runs the jitted code. See the examples at the website.

2-4. No clue...

Hi Jong,

the Assembler::make() returns allocated and runnable function. If you just need to get bytes there are some member functions to get them, just go though getters and you will find them.

you can use getOffset() for example or getCodeSize() to get the size of the binary, and you can use relocCode() to relocate the binary into your own buffer.

The simplest example would be:

Assembler a;

...

void* buf = malloc(a.getCodeSize());

if (buf == NULL) {}

a.relocCode(buf);

Hope that helps

Best,

Petr
