1# Patches 2 3All patches pair with the versions of the referenced repositories defined in `@rules_rust//bindgen:repositories.bzl`. 4 5## [llvm-project.cxx17](./llvm-project.cxx17.patch) 6 7The llvm-project requires a compiler that builds with at least C++14 but there's no configuration 8for this on the targets defined in the repo. This patch plumbs through flags for setting the C++ 9version on targets to avoid any need for bazel configuration flags. If this patch causes issues 10for users with their current toolchain or toolchain definitions then simply defining the `llvm-raw` 11repository before loading `rust_bindgen_dependencies` should avoid this. 12 13## [llvm-project.incompatible_disallow_empty_glob](./llvm-project.incompatible_disallow_empty_glob.patch) 14 15Uses of `glob` are updated to have `allow_empty = True` added so the llvm-project repo is compatible 16with consumers building with [--incompatible_disallow_empty_glob](https://bazel.build/reference/command-line-reference#flag--incompatible_disallow_empty_glob). 17 18Most of this patch is generated using the following regex and replace patterns. There are a handful 19of additional modifications for more extravagant globs. 20 21| regex | replace | 22| --- | --- | 23| `glob\(([\[\w\d_\-\*\/\.\],=\n\s"]+)\) \+` | `glob($1, allow_empty = True) +` | 24| `glob\(([\[\w\d_\-\*\/\.\],=\n\s"]+)\),` | `glob($1, allow_empty = True),` | 25| `(,[\s\n]+), ` | `$1` | 26
