From 905a77077573056d7af508f35373f66ed8b4a39e Mon Sep 17 00:00:00 2001 From: David Gow Date: Sat, 17 Dec 2022 12:44:34 +0800 Subject: [PATCH] rust: arch/um: Use 'pie' relocation mode under UML UML expects a position independent executable for some reason, so tell rustc to generate pie objects. Otherwise we get a bunch of relocations we can't deal with in libcore.
