From 0f3f2c4110fc177b9a37998cb6c426647110d98f Mon Sep 17 00:00:00 2001 From: Rob Pike Date: Tue, 17 Feb 2015 09:49:57 -0800 Subject: [PATCH] [dev.cc] runtime/cgo: change PC to R15 in asm_arm.s R15 is the real register. PC is a pseudo-register that we are making illegal in this context as part of the grand assembly unification.
