From 499b84752140a8b40f8f0956c72357743f755250 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Sat, 5 Mar 2016 04:15:40 +0100 Subject: [PATCH] MIPS: fix mips_cache fallback without __builtin_mips_cache The "R" constraint supplies the address of an variable in a register. Use "r" instead and adjust asm to supply the content of addr in a register instead.
