TimNN added a comment. I didn't manage to repro with `opt`, so still no compilable IR. I did some more debugging, though:
- Inside `removeDeadArgumentsFromCallers`, `CB->getCalledFunction()->dump()` (after the modification) is `define void @_RNvXs0_NtNtCs840rfDNPFol_10proc_macro6bridge3rpchINtB5_6EncodeuE6encodeB9_(i8 %0, ptr noalias noundef align 8 dereferenceable(40) %1, ptr noalias nocapture nonnull readnone align 1 %2) unnamed_addr #0 personality ptr @rust_eh_personality !dbg !18034 { ... }`. **Definition, no `noundef`.** - Inside `callPassesUndefToPassingUndefUBParam`, `Call.getCalledFunction()->dump()` is `declare void @_RNvXs0_NtNtCs840rfDNPFol_10proc_macro6bridge3rpchINtB5_6EncodeuE6encodeB9_(i8 %0, ptr noalias noundef align 8 dereferenceable(40) %1, ptr noalias noundef nonnull align 1 %2) unnamed_addr #2`. **Declaration, `noundef` is back.** Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D133036/new/ https://reviews.llvm.org/D133036 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
