tests: relax expectations after llvm change 902ddda120a5 LLVM 22 is able to drop assumes that seem to not help further optimizations, which actually seems to dramatically _help_ further optimizations in some of our small test cases. I'm a little unclear how to fix the last failure, in `tests/codegen-llvm/issues/issue-122600-ptr-discriminant-update.rs`: ``` -; Function Attrs: mustprogress nofree norecurse nosync nounwind willreturn memory(argmem: readwrite, inaccessiblemem: write) uwtable +; Function Attrs: mustprogress nofree norecurse nosync nounwind nonlazybind willreturn memory(argmem: readwrite, inaccessiblemem: write) uwtable define void ``@update(ptr`` noundef captures(none) %s) unnamed_addr #0 { start: - %_3.sroa.0.0.copyload = load i8, ptr %s, align 1 - %0 = trunc nuw i8 %_3.sroa.0.0.copyload to i1 - %1 = xor i1 %0, true - tail call void ``@llvm.assume(i1`` %1) store i8 1, ptr %s, align 1 ret void } ``` I'm just not conversant enough in LLVM IR to follow the changes here. ``@rustbot`` label llvm-main r? nikic |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
