* Believe it or not, this is a simplification. :-)Bill Wendling2009-09-092-37/+86
| | | | | | | | | | | | | | Basically, this patch is working towards removing the hard-coded values that are output for the CIE. In particular, the CIE augmentation and the CIE augmentation size. Both of these should be calculated. In the process, I was able to make a bunch of code simpler. The encodings for the personality, LSDA, and FDE in the CIE are still not correct. They should be generated either from target-specific callbacks (blech!) or grokked from first-principles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81404 91177308-0d34-0410-b5e6-96231b3b80d8
* remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner2009-09-092-32/+11
| | | | | | | | | | | | | | | the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8
