From baafc71f1fc04ec1d042dc8de9d29d1e24316c4b Mon Sep 17 00:00:00 2001 From: est31 <MTest31@outlook.com> Date: Fri, 18 Sep 2020 08:59:43 +0200 Subject: [PATCH 1/2] Remove unused libc feature gate Libc isn't used by alloc. And std and panic_* use libc from crates.io now, which isn't feature gated. --- library/alloc/src/lib.rs | 1 - library/panic_abort/src/lib.rs | 1 - library/panic_unwind/src/lib.rs | 1 -
