From 0a468a4f3b1c9dea9b31ca51cebd3db58d65e771 Mon Sep 17 00:00:00 2001 From: Ivan Lozano Date: Mon, 13 May 2024 21:03:34 -0400 Subject: rust: made-to-order rust staticlibs Whenever any two Rust static libraries are included as static libraries anywhere in a CC dependency tree, we sometimes get duplicate symbol errors. To avoid this, we no longer directly link multiple rust static libs to CC modules. Instead, we build rust_ffi_rlib modules and produce the actual static library that gets linked against the CC module based on that CC module's full list of Rust rlib dependencies. This introduces a new static_rlibs property for cc modules to define the rust_ffi_rlib dependencies, which are then used to generate the module above. This CL is intended to deprecate rust_ffi_static. It leaves rust_ffi_static and rust_ffi static variants in place until the remaining rust_ffi_static declarations and uses can be removed. In the meantime, rust_ffi_static produces rust_ffi_rlib variants as well to make the transition easier.
