Evan Cheng ec52aaa12f Some ARM implementaions, e.g. A-series, does return stack prediction. That is, ... the processor keeps a return addresses stack (RAS) which stores the address and the instruction execution state of the instruction after a function-call type branch instruction. Calling a "noreturn" function with normal call instructions (e.g. bl) can corrupt RAS and causes 100% return misprediction so LLVM should use a unconditional branch instead. i.e. mov lr, pc b _foo The "mov lr, pc" is issued in order to get proper backtrace. rdar://8979299 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151623 91177308-0d34-0410-b5e6-96231b3b80d8		2012-02-28 06:42:03 +00:00
