cinap_lenrek e4b5f170cf libc: change usize to 64-bit for amd64 and arm64, make memory(2) functions use usize 2021-07-25 15:54:22 +00:00
cinap_lenrek 2c5c784255 prof: properly save and restore RARG for amd64
amd64 passes first argument in RARG (BP) register
which has the be preserved duing _profin() and
_profout() calls. to handle this we introduce
_saveret() and _savearg(). _saveret() returns
AX, _savearg() returns RARG (BP). for archs other
and amd64, _saveret() and _savearg() are the
same function, doing nothing.

restoing works with dummy function:

uintptr
_restore(uintptr, uintptr ret)
{
	return ret;
}

...

ret = _saveret();
arg = _savearg();
...
return _restore(arg, ret);

as we pass arg as the first argument, RARG (BP) is
restored.
