| | | | | | | | | | 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

* Recommitting EH patch; this should answer most of theDale Johannesen2008-04-021-4/+0
| | | | | | | | | | | | | | | | | 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

* SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng2008-02-021-2/+10
| | | | | | | | | | 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

* There is an impedance matching problem between LLVM andDuncan Sands2007-08-271-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Long live the exception handling!Anton Korobeynikov2007-07-141-0/+9
| | | | | | | | | | | | | | | | This patch fills the last necessary bits to enable exceptions handling in LLVM. Currently only on x86-32/linux. In fact, this patch adds necessary intrinsics (and their lowering) which represent really weird target-specific gcc builtins used inside unwinder. After corresponding llvm-gcc patch will land (easy) exceptions should be more or less workable. However, exceptions handling support should not be thought as 'finished': I expect many small and not so small glitches everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@39855 91177308-0d34-0410-b5e6-96231b3b80d8

* The semantics of invoke require that we always jump to the unwind blockDuncan Sands2007-06-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | (landing pad) when an exception unwinds through the call. This doesn't quite match the way the dwarf unwinder works: by default it only jumps to the landing pad if the catch or filter specification matches, and otherwise it keeps on unwinding. There are two ways of specifying to the unwinder that it should "always" (more on why there are quotes here later) jump to the landing pad: follow the specification by a 0 typeid, or follow it by the typeid for the NULL typeinfo. GCC does the first, and this patch makes LLVM do the same as gcc. However there is a problem: the unwinder performs optimizations based on C++ semantics (it only expects destructors to be run if the 0 typeid fires - known as "cleanups"), meaning it assumes that no exceptions will be raised and that the raised exception will be reraised at the end of the cleanup code. So if someone writes their own LLVM code using the exception intrinsics they will get a nasty surprise if they don't follow these rules. The other possibility of using the typeid corresponding to NULL (catch-all) causes the unwinder to make no assumptions, so this is probably what we should use in the long-run. However since we are still having trouble getting exception handling working properly, for the moment it seems best to closely imitate GCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37399 91177308-0d34-0410-b5e6-96231b3b80d8
