If a call argument has the "returned" attribute, we can simplify the call to the value of that argument. The "-inst-simplify" pass already handled this for the constant integer argument case via known bits, which is invoked in SimplifyInstruction. However, non-constant (or non-int) arguments are not handled at all right now. This addresses one of the regressions from D75801. Differential Revision: https://reviews.llvm.org/D75815 |
