Dale Johannesen c66cdf74a9 Enable tail calls on ARM by default, with some ... basic tests. This has been well tested on Darwin but not elsewhere. It should work provided the linker correctly resolves B.W <label in other function> which it has not seen before, at least from llvm-based compilers. I'm leaving the arm-tail-calls switch in until I see if there's any problems because of that; it might need to be disabled for some environments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106299 91177308-0d34-0410-b5e6-96231b3b80d8		2010-06-18 19:00:18 +00:00
