It's not quite that, we have a problem with the following pattern: <https://gcc.godbolt.org/z/4bheaqYev>. `r` is a returned val so it will come from an / as the result of uncasted `alloca`, therefore its address will point to the AllocaAS. C and C++ casts yield bitcasts, not AS casts, so we end up with an C cast expr (see AST) that tries to bitcast from a pointer to the AllocaAS to a pointer to flat / generic, which is invalid. I'm not entirely yet sure how to fix this yet except going to an earlier iteration of this where we use casted `alloca`s everywhere and handle `sret` a bit more noisily. https://github.com/llvm/llvm-project/pull/114062 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
