* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [PDB] Refactor the PDB symbol classes to fix a reuse bug.Zachary Turner2018-09-051-6/+0
| | | | | | | | | | | | | | | | | | | | The way DIA SDK works is that when you request a symbol, it gets assigned an internal identifier that is unique for the life of the session. You can then use this identifier to get back the same symbol, with all of the same internal state that it had before, even if you "destroyed" the original copy of the object you had. This didn't work properly in our native implementation, and if you destroyed an object for a particular symbol, then requested the same symbol again, it would get assigned a new ID and you'd get a fresh copy of the object. In order to fix this some refactoring had to happen to properly reuse cached objects. Some unittests are added to verify that symbol reuse is taking place, making use of the new unittest input feature. llvm-svn: 341503
* [llvm-pdbdump] More advanced class definition dumping.Zachary Turner2017-04-121-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | Previously the dumping of class definitions was very primitive, and it made it hard to do more than the most trivial of output formats when dumping. As such, we would only dump one line for each field, and then dump non-layout items like nested types and enums. With this patch, we do a complete analysis of the object hierarchy including aggregate types, bases, virtual bases, vftable analysis, etc. The only immediately visible effects of this are that a) we can now dump a line for the vfptr where before we would treat that as padding, and b) we now don't treat virtual bases that come at the end of a class as padding since we have a more detailed analysis of the class's storage usage. In subsequent patches, we should be able to use this analysis to display a complete graphical view of a class's layout including recursing arbitrarily deep into an object's base class / aggregate member hierarchy. llvm-svn: 300133
* General usability improvements to generic PDB library.Zachary Turner2017-04-101-1/+3
| | | | | | | | | | | | | | | | | | | | 1. Added some asserts to make sure concrete symbol types don't get constructed with RawSymbols that have an incompatible SymTag enum value. 2. Added new forwarding macros that auto-define an Id/Sym method pair whenever there is a method that returns a SymIndexId. Previously we would just provide one method that returned only the SymIndexId and it was up to the caller to use the Session object to get a pointer to the symbol. Now we automatically get both the method that returns the Id, as well as a method that returns the pointer directly with just one macro. 3. Added some methods for dumping straight to stdout that can be used from inside the debugger for diagnostics during a debug session. 4. Added a clone() method and a cast<T>() method to PDBSymbol that can shorten some usage patterns. llvm-svn: 299831
* Move pdb code into pdb namespace.Zachary Turner2016-05-041-0/+1

* [llvm-pdbdump] Clean up method signatures.Zachary Turner2015-03-011-4/+1

* [llvm-pdbdump] Rewrite dumper using visitor pattern.Zachary Turner2015-02-221-115/+3
| | | | | | | | | | This increases the flexibility of how to dump different symbol types -- necessary for context-sensitive formatting of symbol types -- and also improves the modularity by allowing the dumping to be implemented in the actual dumper, as opposed to in the PDB library. llvm-svn: 230184
* [llvm-pdbdump] Simplify options and output.Zachary Turner2015-02-221-0/+1
| | | | | | | | | This removes a wealth of options, and instead now only provides three options. -symbols, -types, and -compilands. This greatly simplifies use of the tool, and makes it easier to understand what you're going to see when you run the tool. llvm-svn: 230182
* llvm-pdbdump: Add flags controlling the type of values to dump.Zachary Turner2015-02-151-21/+78

* llvm-pdbdump: Only dump whitelisted global symbols.Zachary Turner2015-02-141-24/+27
| | | | | | | | | | Dumping the global scope contains a lot of very uninteresting things and is generally polluted with a lot of random junk. Furthermore, it dumps values unsorted, making it hard to read. This patch dumps known interesting types only, and as a side effect sorts the list by symbol type. llvm-svn: 229232
* llvm-pdbdump: Re-order header files according to LLVM style guide.Zachary Turner2015-02-141-1/+4

* llvm-pdbdump: Improve printing of functions and signatures.Zachary Turner2015-02-131-0/+20
| | | | | | | | | This correctly prints the function pointers, and also prints function signatures for symbols as opposed to just types. So actual functions in your program will now be printed with full name and signature, as opposed to just name as before. llvm-svn: 229129
* Re-sort #include lines using my handy dandy ./utils/sort_includes.pyChandler Carruth2015-02-131-2/+1
| | | | | | script. This is in preparation for changes to lots of include lines. llvm-svn: 229088
* llvm-pdbdump: Add more comprehensive dumping of symbol types.Zachary Turner2015-02-131-7/+8
| | | | | | | | | In particular this patch adds the ability to dump complete function signature information including argument types as correctly formatted strings. A side effect of this is that almost all symbol and meta types are now formatted. llvm-svn: 229076
* Improve llvm-pdbdump output display.Zachary Turner2015-02-131-4/+7
| | | | | | | | | | | | This patch adds a number of improvements to llvm-pdbdump. 1) Dumping of the entire global scope, and not only those symbols that live in individual compilands. 2) Prepend class name to member functions and data 3) Improved display of bitfields. 4) Support for dumping more kinds of data symbols. llvm-svn: 229012
* Rewrite llvm-pdbdump in terms of LLVMDebugInfoPDB.Zachary Turner2015-02-101-1/+26
| | | | | | | | | | | | | This makes llvm-pdbdump available on all platforms, although it will currently fail to create a dumper if there is no PDB reader implementation for the current platform. It implements dumping of compilands and children, which is less information than was previously available, but it has to be rewritten from scratch using the new set of interfaces, so the rest of the functionality will be added back in subsequent commits. llvm-svn: 228755
* Make PDBSymbol's IPDBSymbol reference const.Zachary Turner2015-02-081-1/+1
| | | | llvm-svn: 228553
* DebugInfoPDB: Make the symbol base case hold an IPDBSession ref.Zachary Turner2015-02-081-2/+3
| | | | | | | | | Dumping a symbol often requires access to data that isn't inside the symbol hierarchy, but which is only accessible through the top-level session. This patch is a pure interface change to give symbols a reference to the session. llvm-svn: 228542
* Removed unused function mistakenly left in, triggering -Werror.Zachary Turner2015-02-081-21/+0

* Some cleanup for libpdb.Zachary Turner2015-02-081-0/+45
This patch implements a few of the optional suggestions from the initial patch comitting libpdb. In particular, it implements a virtual function out of line for each of the concrete classes. A few other minor cleanups exist as well, such as using override instead of virtual, etc. llvm-svn: 228516
