@LegNeato this is a much cleaner approach, what do you think? can we see if CI passes? |

Add the initial llvm19 cargo/build.rs plumbing while preserving the llvm7\ncheck path. Assemble a v19 libintrinsics bitcode at build time and route\nnvvm.rs through the build-script-provided path.\n\nDocument the validated baseline on the current host and the first Layer 1\nblocker: the existing C++ shim no longer builds unchanged against LLVM 19\nbecause rustllvm.h still expects headers like llvm/ADT/Triple.h. RUST_CUDA_ALLOW_LEGACY_ARCH_WITH_LLVM19 compute_100 target working through compilation errors working throw sigsegv on vecadd nix flake libintrinsics libintrinsics chore(llvm19): close out Layer 3 pre-smoke work Finalize the Layer 3 plan, add env-driven final-module and LLVM IR capture hooks to vecadd, and validate the harness locally so the next phase can move straight to CUDA 12.9+ smoke testing. refactor(llvm19): close out Layer 2 containment Add named Rust-side containment helpers for debug info and target machine creation, make the current ThinLTO behavior explicit, and update LLVM19_PLAN.md to mark Layers 2c and 2d complete. refactor(llvm19): start Layer 2 helper containment Add a small Rust-side helper surface in src/llvm.rs for call-building, symbol insertion, and debug-location setting, then migrate the obvious callers without introducing LLVM-version cfg branching. Update LLVM19_PLAN.md to reflect the real Layer 2 state: 2a is complete, 2b is complete, 2c is partially landed, and 2d is still pending. Include the current .gitignore change in this checkpoint as requested. feat(llvm19): complete Layer 1 C++ shim bridge Bridge the wrapper headers and C++ shims so rustc_codegen_nvvm now builds against both LLVM 7 and LLVM 19. This adds the LLVM 19 wrapper headers, ports RustWrapper.cpp and PassWrapper.cpp through the current checkpoint, and records the completed Layer 1 progress and remaining Layer 2 caveats in the plan. ptxjitcompiler.so load_ptx_with_log unified?
