Memory buffer should be a std::unordered_map #11

Open NaC-L opened 3 weeks ago

NaC-L commented 3 weeks ago

https://github.com/NaC-L/Mergen/blob/main/lifter/GEPTracker.cpp#L73 should be an unordered_map,

why?

less space
related to an unknown bug
also use it for non-stack values

steps?

remove .size checks https://github.com/NaC-L/Mergen/blob/main/lifter/GEPTracker.cpp#L109
we cant assume values are 0 if we havent writed it, under the stack ( because we assume the value would be 0 ) and above the stack

Also probably refactor the whole class when modifying that
