* Modify the code that emits the module flags to use the new module flags accessorBill Wendling2012-02-151-2/+4
| | | | | | | | | method. This allows the target lowering code to not have to deal with MDNodes. Also, avoid leaking memory like a sieve by not creating a global variable for the image info section, but just emitting the code directly. llvm-svn: 150624
* Add code to the target lowering object file module to handle module flags.Bill Wendling2012-02-141-0/+4
| | | | | | | | The MachO back-end needs to emit the garbage collection flags specified in the module flags. This is a WIP, so the front-end hasn't been modified to emit these flags just yet. Documentation and front-end switching to occur soon. llvm-svn: 150507

* reapply the patches reverted in r149470 that reenable ConstantDataArray,Chris Lattner2012-02-051-23/+10
| | | | | | | | | but with a critical fix to the SelectionDAG code that optimizes copies from strings into immediate stores: the previous code was stopping reading string data at the first nul. Address this by adding a new argument to llvm::getConstantStringInfo, preserving the behavior before the patch. llvm-svn: 149800

* Chris's constant data sequence refactoring actually enabled printingChandler Carruth2012-01-301-1/+1
| | | | | | | | | | | | | | | | vectors of all one bits to be printed more cleverly in the AsmPrinter. Unfortunately, the byte value for all one bits is the same with -fsigned-char as the error return of '-1'. Force this to be the unsigned byte value when returning it to avoid this problem, and update the test case for the shiny new behavior. Yay for building LLVM and Clang with -funsigned-char. Chris, please review, and let me know if there is any reason to not desire this change. It seems good on the surface, and certainly intended based on the code written. llvm-svn: 149299

| | | | | | | | This change adds an new option --arm-enable-ehabi-descriptors that enables emitting unwinding descriptors. This provides a mode with a working backtrace() without the (currently broken) exception support. llvm-svn: 148800

* Add AsmPrinter (aka MCLowering) support for ConstantDataSequential, Chris Lattner2012-01-241-32/+91
| | | | | | | | and clean up some other misc stuff. 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 llvm-svn: 148793
* Revert r148686 (and r148694, a fix to it) due to a serious layeringChandler Carruth2012-01-241-20/+5
| | | | | | | | | | | | | | | | | | 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
