2009-07-13Begin the painful process of tearing apart the rat'ss nest that is ↵Owen Anderson
Constants.cpp and ConstantFold.cpp. This involves temporarily hard wiring some parts to use the global context.

2009-03-10Global variables don't have a corresponding llvm.dbg.declare, yet it is possibleTorok Edwin
to obtain debug info about them. Introduce helpers to access debug info for global variables. Also introduce a helper that works for both local and global variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66541 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-07Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands
and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-17The debugger sometimes lookup dynamically in the runtime to find ivar info ↵Devang Patel
of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF. Add support for two additional DWARF attributes to encode Objective-C runtime version number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64834 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-30 Each input file is encoded as a separate compile unit in LLVM debuggingDevang Patel
information output. However, many target specific tool chains prefer to encode only one compile unit in an object file. In this situation, the LLVM code generator will include debugging information entities in the compile unit that is marked as main compile unit. The code generator accepts maximum one main compile unit per module. If a module does not contain any main compile unit then the code generator will emit multiple compile units in the output object file. [Part 1] Update DebugInfo APIs to accept optional boolean value while creating DICompileUnit to mark the unit as "main" unit. By defaults all units are considered non-main. Update SourceLevelDebugging.html to document "main" compile unit. Update DebugInfo APIs to not accept and encode separate source file/directory entries while creating various llvm.dbg.* entities. There was a recent, yet to be documented, change to include this additional information so no documentation changes are required here. Update DwarfDebug to handle "main" compile unit. If "main" compile unit is seen then all DIEs are inserted into "main" compile unit. All other compile units are used to find source location for llvm.dbg.* values. If there is not any "main" compile unit then create unique compile unit DIEs for each llvm.dbg.compile_unit. [Part 2] Create separate llvm.dbg.compile_unit for each input file. Mark compile unit create for main_input_filename as "main" compile unit. Use appropriate compile unit, based on source location information collected from the tree node, while creating llvm.dbg.* values using DebugInfo APIs. --- This is Part 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63400 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-23Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, ↵Devang Patel
DW_AT_APPLE_flags. DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way. DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by a project, irrespective of whether the project used makefile, Xcode or something else. llvm-gcc patch is next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62888 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
