- Bcc:
I understand that gcc-help might be a more suitable list to send this but I
think this is a little advanced question and I would like to have an answer
from a developer.
I want to do something like this:
(code)
asm_function_that_alters_general_purpose_registers_WITHOUT_restoring_them();
(other code)
I am quite sure that this will break things. (Right?)
But what about this?
(code)
asm_function-that_alters_general_purpose_registers_without_restoring_them();
asm volatile("" : : : "memory");
(other code)
The program will break?
I am not interested in portability, just gcc.
Thank you in advace for any answer and please CC me.
