2009-09-20Here's fun! It turns out that these filter functions can be internal. If they'reBill Wendling
internal, they shouldn't use the indirect pointer stuff. In the case of throw_rethrow_test, it was marked as 'internal' and calculated its own offset to its contents. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82354 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18It's inefficient to have place the exception tables (which contain the LSDA)Bill Wendling
into the __DATA section. At launch time, dyld has to update most of the section to fix up the type info pointers. It's better to place it into the __TEXT section and use pc-rel indirect pointer encodings. Similar to the personality routine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82274 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-16Big change #1 for personality function references:Chris Lattner
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding fields from MAI: they aren't part of the asm syntax, they are related to the structure of the object file. To replace their functionality, add a new TLOF::getSymbolForDwarfGlobalReference method which asks targets to decide how to reference a global from EH in a pc-relative way. The default implementation just returns the symbol. The default darwin implementation references the symbol through an indirect $non_lazy_ptr stub. The bizarro x86-64 darwin specialization handles the weird "foo@GOTPCREL+4" hack. DwarfException.cpp now uses this to emit the reference to the symbol in the right way, and this also eliminates another horrible hack from DwarfException.cpp: - if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL")) - O << "-" << MAI->getPCSymbol(); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81991 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-12devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden.Chris Lattner
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that we only have one place that decides what to name bb labels.

2009-09-11Fix PR4948 (and a leak): by not destroying the DwarfExceptionDuncan Sands

2009-09-10Revert part of my r81424 patch. I removed what looked like superfluous paddingBill Wendling
from the exception tables. However, Duncan explained why it's a can of worms to do it the GCC way. I went back to doing it the LLVM way and added Duncan's explanation so that I don't do this again in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81434 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-10Don't hardcode the TType format size. In fact, rework the code so that it's moreBill Wendling
like what GCC outputs. The mysterious code to insert padding wasn't in GCC at all. I modified the TType base offset code to calculate the offset like GCC does, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81424 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-10Remove the "#if 0" that Noone loved. It wasn't really necessary, because theBill Wendling
code within it was the same inside and out. There's still a problem of the TypeInfoSize should be the size of the TType format encoding (at least that's what GCC thinks it should be). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81417 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-09Believe it or not, this is a simplification. :-)Bill Wendling
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
2009-09-09remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner
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

2009-09-01Clean up LSDA name generation and use for SJLJ exception handling. ThisJim Grosbach
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward and making it a GV available for reference would be even better, but is beyond the scope of what I'm looking to solve at this point. Objective C++ code could generate function names that broke the previous scheme. This fixes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80649 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-31PR4747Jim Grosbach
Shared landing pads run into trouble with SJLJ, as the dispatch table is mapped to call sites, and merging the pads will throw that off. There needs to be a one-to-one mapping of landing pad exception table entries to invoke call points. Detecting the shared pad during lowering of SJLJ info insn't sufficient, as the dispatch function may still need separate destinations to properly handle phi-nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80530 91177308-0d34-0410-b5e6-96231b3b80d8
