From 2e6b57541dc28cdd954b1ce2300b88ccc5c29d5c Mon Sep 17 00:00:00 2001 From: Paul Menage Date: Mon, 9 Oct 2023 02:22:14 -0700 Subject: Add -Z llvm_module_flag Allow adding values to the `!llvm.module.flags` metadata for a generated module. The syntax is `-Z llvm_module_flag=:::` Currently only u32 values are supported but the type is required to be specified for forward compatibility. The `behavior` element must match one of the named LLVM metadata behaviors.viors. This flag is expected to be perma-unstable. --- src/doc/unstable-book/src/compiler-flags/llvm-module-flag.md | 12 ++++++++++++ 1 file changed, 12 insertions(+) create mode 100644 src/doc/unstable-book/src/compiler-flags/llvm-module-flag.md (limited to 'src/doc') diff --git a/src/doc/unstable-book/src/compiler-flags/llvm-module-flag.md b/src/doc/unstable-book/src/compiler-flags/llvm-module-flag.md new file mode 100644 index 00000000000..454ad0a9a6d --- /dev/null +++ b/src/doc/unstable-book/src/compiler-flags/llvm-module-flag.md @@ -0,0 +1,12 @@ +# `llvm-module-flag` + +--------------------- + +This flag allows adding a key/value to the `!llvm.module.flags` metadata in the +LLVM-IR for a compiled Rust module.
