Hal Finkel c078e835f2 [BDCE] Don't forget uses of root instructions seen before the instruction itself ... When visiting the initial list of "root" instructions (those which must always be alive), for those that are integer-valued (such as invokes returning an integer), we mark their bits as (initially) all dead (we might, obviously, find uses of those bits later, but all bits are assumed dead until proven otherwise). Don't do so, however, if we're already seen a use of those bits by another root instruction (such as a store). Fixes a miscompile of the sanitizer unit tests on x86_64. Also, add a debug line for visiting the root instructions, and remove a debug line which tried to print instructions being removed (printing dead instructions is dangerous, and can sometimes crash). llvm-svn: 229618		2015-02-18 03:12:28 +00:00
