From c775aa12307efecb00ea78265210535dc41cdd49 Mon Sep 17 00:00:00 2001 From: Toma Tabacu Date: Tue, 24 Feb 2015 15:25:11 +0000 Subject: [PATCH] MIPS: LLVMLinux: Silence variable self-assignment warnings. Remove variable self-assignments. This silences a bunch of -Wself-assign warnings reported by clang. The changed code can be compiled without warnings by both gcc and clang.
