Chandler Carruth 701073e58e [optnone] Make the optnone attribute effective at suppressing function ... attribute and function argument attribute synthesizing and propagating. As with the other uses of this attribute, the goal remains a best-effort (no guarantees) attempt to not optimize the function or assume things about the function when optimizing. This is particularly useful for compiler testing, bisecting miscompiles, triaging things, etc. I was hitting specific issues using optnone to isolate test code from a test driver for my fuzz testing, and this is one step of fixing that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215538 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-13 10:49:33 +00:00
