Ekaterina Romanova	8d62008ecb	Fix for http://llvm.org/bugs/show_bug.cgi?id=18590 This patch fixes the bug in peephole optimization that folds a load which defines one vreg into the one and only use of that vreg. With debug info, a DBG_VALUE that referenced the vreg considered to be a use, preventing the optimization. The fix is to ignore DBG_VALUE's during the optimization, and undef a DBG_VALUE that references a vreg that gets removed. Patch by Trevor Smigiel! llvm-svn: 203829	2014-03-13 18:47:12 +00:00
