This allows code gen and the exception table writer to cooperate to make sure landing pads are associated with the correct invoke locations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94726 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-09Extract scope information from the variable itself, instead of relying on ↵Devang Patel
alloca or llvm.dbg.declare location. While recording beginning of a function, use scope info from the first location entry instead of just relying on first location entry itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83684 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-01If location info is attached with an instruction then keep track of alloca ↵Devang Patel
slots used by a variable. This info will be used by AsmPrinter to emit debug info for variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83189 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-10DebugLabelFolder ruthlessly deletes redundant labels. However, sometimes the ↵Devang Patel
redundant labels is referenced by debug info somewhere else. This patch provies a way so that dwarf writer can mark labels as used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68813 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-13Removoe MachineModuleInfo methods (and related DebugInfoDesc class ↵Devang Patel
hierarchy) that were used to handle debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62199 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-13Keep "has debug info" big in MachineModuleInfo to avoid circular dependency ↵Devang Patel
between AsmPrinter and CodeGen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62191 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-17Today the front-ends (llvm-gcc and clang) generate multiple ↵Devang Patel
llvm.dbg.compile_units to identify source file for various debug entities. Each llvm.dbg.compile_unit matches one file on the disk. However, the backend only supports one DW_TAG_compile_unit per .o file. The backend selects first compile_unit from the vector to construct DW_TAG_compile_unit entry, which is not correct in all cases. First step to resolve this is, record file name and directory directly in debug info for various debug entities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61164 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-16Move the include of MachineLocation.h into MachineModuleInfo.hDan Gohman

2008-06-27- Remove a use of std::vector.Bill Wendling
- Make sure that we're not recalculating the size of a vector that never changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52803 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-02Recommitting EH patch; this should answer most of theDale Johannesen
review feedback. -enable-eh is still accepted but doesn't do anything. EH intrinsics use Dwarf EH if the target supports that, and are handled by LowerInvoke otherwise. The separation of the EH table and frame move data is, I think, logically figured out, but either one still causes full EH info to be generated (not sure how to split the metadata correctly). MachineModuleInfo::needsFrameInfo is no longer used and is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49064 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-25A quick nm audit turned up several fixed tables and objects that wereDan Gohman
marked read-write. Use const so that they can be allocated in a read-only segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48800 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-02SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng
information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc. Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes. For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46659 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-27There is an impedance matching problem between LLVM andDuncan Sands
gcc exception handling: if an exception unwinds through an invoke, then execution must branch to the invoke's unwind target. We previously tried to enforce this by appending a cleanup action to every selector, however this does not always work correctly due to an optimization in the C++ unwinding runtime: if only cleanups would be run while unwinding an exception, then the program just terminates without actually executing the cleanups, as invoke semantics would require. I was hoping this wouldn't be a problem, but in fact it turns out to be the cause of all the remaining failures in the LLVM testsuite (these also fail with -enable-correct-eh-support, so turning on -enable-eh didn't make things worse!). Instead we need to append a full-blown catch-all to the end of each selector. The correct way of doing this depends on the personality function, i.e. it is language dependent, so can only be done by gcc. Thus this patch which generalizes the eh.selector intrinsic so that it can handle all possible kinds of action table entries (before it didn't accomodate cleanups): now 0 indicates a cleanup, and filters have to be specified using the number of type infos plus one rather than the number of type infos. Related gcc patches will cause Ada to pass a cleanup (0) to force the selector to always fire, while C++ will use a C++ catch-all (null). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41484 91177308-0d34-0410-b5e6-96231b3b80d8
