[AVR] Explicitly set the target in all CodeGen tests This seems to have caused failures on the buildbot. llvm-svn: 289324 2016-12-10 19:23:16 +08:00			`; RUN: llc < %s -march=avr \| FileCheck %s`
[AVR] Support stores to undefined pointers This would previously trigger an assertion error in AVRISelDAGToDAG. llvm-svn: 289321 2016-12-10 18:16:13 +08:00
