* Drop materializeAllPermanently.Rafael Espindola2015-12-181-1/+1
| | | | | | | | This inlines materializeAll into the only caller (materializeAllPermanently) and renames materializeAllPermanently to just materializeAll. llvm-svn: 256024
* Use std::unique_ptr to manage the DataStreamer in bitcode parsing.Rafael Espindola2015-06-161-2/+3

* Fix input validation issues in llvm-as/llvm-disAlexey Samsonov2015-05-111-8/+8
| | | | | | | | | | | | | | | | | | Summary: 1. llvm-as/llvm-dis tools do not check for input filename length. 2. llvm-dis does not verify the `Streamer` variable against `nullptr` properly, so the `M` variable could be uninitialized (e.g. if the input file does not exist) leading to null dref.

* IR: Give 'DI' prefix to debug info metadataDuncan P. N. Exon Smith2015-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. llvm-svn: 236120
* DebugInfo: Drop rest of DIDescriptor subclassesDuncan P. N. Exon Smith2015-04-211-4/+2
| | | | | | | Delete the remaining subclasses of (the already deleted) `DIDescriptor`. Part of PR23080. llvm-svn: 235404
* uselistorder: Remove the global bitsDuncan P. N. Exon Smith2015-04-151-2/+6
| | | | | | | | | | | | | Remove all the global bits to do with preserving use-list order by moving the `cl::opt`s to the individual tools that want them. There's a minor functionality change to `libLTO`, in that you can't send in `-preserve-bc-uselistorder=false`, but making that bit settable (if it's worth doing) should be through explicit LTO API. As a drive-by fix, I removed some includes of `UseListOrder.h` that were made unnecessary by recent commits. llvm-svn: 234973
* uselistorder: Pull the assembly bit up out of the printerDuncan P. N. Exon Smith2015-04-151-1/+2
| | | | | | | | Pull the `-preserve-ll-uselistorder` bit up through all the callers of `Module::print()`. I converted callers of `operator<<` to `Module::print()` where necessary to pull the bit through. llvm-svn: 234968
* DebugInfo: Gut DIVariable and DIGlobalVariableDuncan P. N. Exon Smith2015-04-141-2/+2
| | | | | | | | | | Gut all the non-pointer API from the variable wrappers, except an implicit conversion from `DIGlobalVariable` to `DIDescriptor`. Note that if you're updating out-of-tree code, `DIVariable` wraps `MDLocalVariable` (`MDVariable` is a common base class shared with `MDGlobalVariable`). llvm-svn: 234840
* llvm-dis: Use the new `DebugLoc` API, NFCDuncan P. N. Exon Smith2015-03-301-8/+4
| | | | | | Update tools/llvm-dis to use the new `DebugLoc` API. llvm-svn: 233590
* llvm-dis: Stop crashing when dropping debug infoDuncan P. N. Exon Smith2015-02-251-3/+10
| | | | | | | | | | | | | | | | | | Since r199356, we've printed a warning when dropping debug info. r225562 started crashing on that, since it registered a diagnostic handler that only expected errors. This fixes the handler to expect other severities. As a side effect, it now prints "error: " at the start of error messages, similar to `llvm-as`. There was a testcase for r199356, but it only really checked the assembler. Move `test/Bitcode/drop-debug-info.ll` to `test/Assembler`, and introduce `test/Bitcode/drop-debug-info.3.5.ll` (and companion `.bc`) to test the bitcode reader. Note: tools/gold/gold-plugin.cpp has an equivalent bug, but I'm not sure what the best fix is there. I'll file a PR. llvm-svn: 230416
* Use the DiagnosticHandler to print diagnostics when reading bitcode.Rafael Espindola2015-01-101-19/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bitcode reading interface used std::error_code to report an error to the callers and it is the callers job to print diagnostics. This is not ideal for error handling or diagnostic reporting: * For error handling, all that the callers care about is 3 possibilities: * It worked * The bitcode file is corrupted/invalid. * The file is not bitcode at all. * For diagnostic, it is user friendly to include far more information about the invalid case so the user can find out what is wrong with the bitcode file. This comes up, for example, when a developer introduces a bug while extending the format. The compromise we had was to have a lot of error codes. With this patch we use the DiagnosticHandler to communicate with the human and std::error_code to communicate with the caller. This allows us to have far fewer error codes and adds the infrastructure to print better diagnostics. This is so because the diagnostics are printed when he issue is found. The code that detected the problem in alive in the stack and can pass down as much context as needed. As an example the patch updates test/Bitcode/invalid.ll. Using a DiagnosticHandler also moves the fatal/non-fatal error decision to the caller. A simple one like llvm-dis can just use fatal errors. The gold plugin needs a bit more complex treatment because of being passed non-bitcode files. An hypothetical interactive tool would make all bitcode errors non-fatal. llvm-svn: 225562

* Modernize raw_fd_ostream's constructor a bit.Rafael Espindola2014-08-251-4/+4
| | | | | | | | | | Take a StringRef instead of a "const char *". Take a "std::error_code &" instead of a "std::string &" for error. A create static method would be even better, but this patch is already a bit too big. llvm-svn: 216393

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-4/+4
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083

* Replace the F_Binary flag with a F_Text one.Rafael Espindola2014-02-241-1/+1
| | | | | | | | | After this I will set the default back to F_None. The advantage is that before this patch forgetting to set F_Binary would corrupt a file on windows. Forgetting to set F_Text produces one that cannot be read in notepad, which is a better failure mode :-) llvm-svn: 202052

* Move the LLVM IR asm writer header files into the IR directory, as theyChandler Carruth2014-01-071-1/+1
| | | | | | | | | | | | | | | | | are part of the core IR library in order to support dumping and other basic functionality. Rename the 'Assembly' include directory to 'AsmParser' to match the library name and the only functionality left their -- printing has been in the core IR library for quite some time. Update all of the #includes to match. All of this started because I wanted to have the layering in good shape before I started adding support for printing LLVM IR using the new pass infrastructure, and commandline support for the new pass infrastructure. llvm-svn: 198688
* Revert "Encapsulate PassManager debug flags to avoid static init and cxa_exit."Andrew Trick2013-09-191-3/+0
| | | | | | | | Working on a better solution to this. This reverts commit 7d4e9934e7ca83094c5cf41346966c8350179ff2. llvm-svn: 190990
* Encapsulate PassManager debug flags to avoid static init and cxa_exit.Andrew Trick2013-09-181-0/+3
| | | | | | | | | | | | | | This puts all the global PassManager debugging flags, like -print-after-all and -time-passes, behind a managed static. This eliminates their static initializers and, more importantly, exit-time destructors. The only behavioral change I anticipate is that tools need to initialize the PassManager before parsing the command line in order to export these options, which makes sense. Tools that already initialize the standard passes (opt/llc) don't need to do anything new. llvm-svn: 190974
* Add a wrapper for open.Rafael Espindola2013-07-161-3/+2
| | | | | | | This centralizes the handling of O_BINARY and opens the way for hiding more differences (like how open behaves with directories). llvm-svn: 186447

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-4/+4
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366
* Sort the #include lines for tools/...Chandler Carruth2012-12-041-5/+5
| | | | | | | | Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. llvm-svn: 169252

| | | | | | | | | include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. The reasoning is because the DebugInfo module is simply an interface to the debug info MDNodes and has nothing to do with analysis. llvm-svn: 159312
