@theRealAph It was decided in that discussion to cap the maximum value of BciProfileWidth (a debug option) at 1000 across all platforms. Even this limit is already excessive, since methods with thousands of ret bytecodes are extremely uncommon. Unless there is another legitimate way to enlarge the MDO, I don’t think AArch64 code should be adjusted just to accommodate this artificial case.
