First of all let me say that all I've done for the past several days is read,
read read.I have read the rpython and pypy documentation. I've read
bolz-tracing-jit-final.pdf as well as antocuni-phd-thesis.pdf. I also feel that
I comprehended most of what I read.
In studying the vmprof implementation there is still a gap in my comprehension.
How do I get access to PyFrame within assembly.py ?
VmProf dumps everything into a specially formatted binary file, embedded with
variousmarkers and the function code objects among many other stuff, per
PyFrame which gets executed. This file later gets post-processed by the vmprof
tool.
Suppose I do something similar to vmprof in order to obtain access to function
code objects, i.e. see below. But how do I get access to PyFrame in the x86
backend code at run time ?
_get_code = lambda frame, w_inputvalue, operr: frame.pycode
_decorator = rvmprof.vmprof_execute_code("pypy", _get_code, W_Root)
my_execute_frame = _decorator(PyFrame.execute_frame)
class __extend__(PyFrame):
def execute_frame(self, w_inputvalue=None, operr=None):
# indirection for the optional arguments
return my_execute_frame(self, w_inputvalue, operr) _______________________________________________
