From 7261a4b4d5778a48c8d72c9125233b1b0bc009e6 Mon Sep 17 00:00:00 2001 From: Pgowda Date: Wed, 29 Sep 2021 06:20:54 -0700 Subject: [PATCH] Fix rust-native build issue when debug is enabled When DEBUG_BUILD is set for building rust-native, it generated error as follows:- ========================================================= Building : rustdoc, rustdoc-json-types error[E0463]: can't find crate for `rustc_llvm` which `rustc_driver` depends on --> src/librustdoc/lib.rs:37:1 | 37 | extern crate rustc_driver; | ^^^^^^^^^^^^^^^^^^^^^^^^^^ can't find crate ========================================================= On analyzing the issue, it was found that rustc_llvm crate was present at required path. However, it was very huge due to the presence of debugging information. Hence, it was somehow not recognized as a valid crate. The following patch removes the debug information from rust-llvm-native which is built prior to rust-native but retains debug information as required in rust-native binaries.
