Implementation:
|
|
The tracker registers hooks to tcmalloc allocator for
|
|
functions explicitly declared as being tracked. Now, we tracker every APIs in
|
|
emugl translator library as "EMUGL". When the hooks are
|
|
invoked, the callback function gets the backtraces as a list of program
|
|
counters. Then, it walks up the stack and checks if any registerd
|
|
function is used in this malloc/free operation. Once hit, it will record
|
|
stats for total allocation and live memory for each individual function.
