* An option to selectively enable part of ARM EHABI support.Evgeniy Stepanov2012-01-242-5/+15
| | | | | | | | | This change adds an new option --arm-enable-ehabi-descriptors that enables emitting unwinding descriptors.

Unlike ConstantArray, we will prefer to emit .fill directives for "String" arrays that all have the same value, since they are denser than emitting a .ascii git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148793 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert r148686 (and r148694, a fix to it) due to a serious layeringChandler Carruth2012-01-245-29/+14
| | | | | | | | | | | | | | | | | | violation -- MC cannot depend on CodeGen. Specifically, the MCTargetDesc component of each target is actually a subcomponent of the MC library. As such, it cannot depend on the target-independent code generator, because MC itself cannot depend on the target-independent code generator. This change moved a flag from the ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in ARMException.cpp, leaving behind an 'extern' to refer back to it. That layering order isn't viable givin the constraints outlined above. Commandline flags are designed to be static specifically to avoid these types of bugs. Fixing this is likely going to require some non-trivial refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148759 91177308-0d34-0410-b5e6-96231b3b80d8
