Chandler Carruth	ed975232bc	Revert r148686 (and r148694, a fix to it) due to a serious layering ... 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. llvm-svn: 148759	2012-01-24 00:30:17 +00:00
Evgeniy Stepanov	482cdc4ebd	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. llvm-svn: 148686	2012-01-23 07:57:39 +00:00
Evan Cheng	76792992d6	Add MCObjectFileInfo and sink the MCSections initialization code from ... TargetLoweringObjectFileImpl down to MCObjectFileInfo. TargetAsmInfo is done to one last method. It's *almost* gone! llvm-svn: 135569	2011-07-20 05:58:47 +00:00
Evan Cheng	67c033e6b8	Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions for ... better location welcome). llvm-svn: 135438	2011-07-18 22:29:13 +00:00
Rafael Espindola	fc9bae6f8b	Replace the -unwind-tables option with a per function flag. This is more ... LTO friendly as we can now correctly merge files compiled with or without -fasynchronous-unwind-tables. llvm-svn: 132033	2011-05-25 03:44:17 +00:00
Anton Korobeynikov	a7ec2dcefd	Some first rudimentary support for ARM EHABI: print exception table in "text mode". ... llvm-svn: 127099	2011-03-05 18:43:15 +00:00
