[X86] add dwarf annotation for inline stack probe

Authored by YangKeao on Mar 30 2021, 5:02 AM.



While probing stack, the stack register is moved without dwarf
information, which could cause panic if unwind the backtrace.
This commit only add annotation for the inline stack probe case.
Dwarf information for the loop case should be done in another
patch and need further discussion.

@nagisa This is the inline part of D98789 😋 .

I installed clang-format later, and nothing found (there is no lint message). How could I update this patch and remove the "clang-format not found in user's PATH; not linting file." warning? (or just left it here 😋 )

You can remove these notices by running arc diff again with clang-format in your PATH. It is also fine to just leave these messages in – CI will verify the formatting as well and fail if its not correct. Only then it is strictly necessary to rediff your code.

Do you have ability to commit this yourself, or would you need somebody to do it for you?
