Summary Incorrect assertion inside AccessCase
Saam Barati
Reported 2017-12-31 16:59:30 PST
In a setter like: ``` o.f = o; ``` The DFG will often assign the same registers to the baseGPR (o in o.f) and the valueRegsPayloadGPR (o in the RHS). The code totally works when these are assigned to the same register. However, we're asserting that they're not the same register.
