Emit ARM EHABI unwinding instructions for 3 more Thumb instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148473 91177308-0d34-0410-b5e6-96231b3b80d8 2012-01-19 12:53:06 +00:00			`; Test that the EHABI unwind instruction generator does not encounter any`

An option to selectively enable parts of ARM EHABI support. This change adds an new value to the --arm-enable-ehabi option that disables emitting unwinding descriptors. This mode gives a working backtrace() without the (currently broken) exception support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148686 91177308-0d34-0410-b5e6-96231b3b80d8 2012-01-23 07:57:39 +00:00			`; RUN: llc < %s -mtriple=thumbv7 -arm-enable-ehabi=full -disable-fp-elim`
