HLIL Doesn't Currently Retrieve `this` pointer
Atm if one loads up binaries such as win32kfull.sys and attempts to decompile a function with a this pointer in its function defininition, such as ESTROBJ::ptlBaseLineAdjustSet, the definition in Binary Ninja will be as though the invisible this pointer never existed. This makes it incredibly annoying to correct HLIL output that uses the this pointer in its code. This can be seen in the image below.
On the contrary, programs like Relyze are able to recognize that this function has a hidden this parameter from the PDB information:
This is dependent on this issue #604
PDBs now properly annotate this parameters and thiscall functions, so combining the fixing of #604 with the new PDB loader in 3.1.3715-dev, this is now fixed.
