| | | | | | | | | No-one was using this, and it's not meaningful in general -- FrontendActions can be run on inputs that don't have a corresponding source file. The current frontend input can be obtained by asking the FrontendAction if any future action actually needs it. llvm-svn: 305045

| | | | | | | | 'CXTranslationUnit_SingleFileParse' that puts preprocessor in a mode for parsing a single file only. This is useful for parsing a single file, as a fast/inaccurate 'mode' that can still provide declarations from the file, like the classes and their methods. llvm-svn: 305044

* Represent debug information compression type fullySaleem Abdulrasool2017-06-094-7/+12
| | | | | | | | | | | This is tied with the LLVM side of the change to expose the debug information compression types to clang. We now track the compression type as an enumeration rather than a boolean. We still use the same value (GNU) that we did previously. This is in preparation to support passing down the compression type and switch it based on the command line. llvm-svn: 305039
* sink DebugCompressionType into MC for exposing to clangSaleem Abdulrasool2017-06-096-32/+33
| | | | | | | | | | | | | | This is a preparatory change to expose the debug compression style to clang. It requires exposing the enumeration and passing the actual value through to the backend from the frontend in actual value form rather than a boolean that selects the GNU style of debug info compression. Minor tweak to the ELF Object Writer to use a variable for re-used values. Add an assertion that debug information format is one of the two currently known types if debug information is being compressed. llvm-svn: 305038
* [CodeView] Support remaining debug subsection typesZachary Turner2017-06-0919-132/+637
| | | | | | | | | | | | | | | | This adds support for Symbols, StringTable, and FrameData subsection types. Even though these subsections rarely if ever appear in a PDB file (they are usually in object files), there's no theoretical reason why they *couldn't* appear in a PDB. The real issue though is that in order to add support for dumping and writing them (which will be useful for object files), we need a way to test them. And since there is no support for reading and writing them to / from object files yet, making PDB support them is the best way to both add support for the underlying format and add support for tests at the same time. Later, when we go to add support for reading / writing them from object files, we'll need only minimal changes in the underlying read/write code. llvm-svn: 305037

* [llvm-pdbdump] Support native ordering of subsections in raw mode.Zachary Turner2017-06-0812-392/+343
| | | | | | | | | | | | | This is the same change for the YAML Output style applied to the raw output style. Previously we would queue up all subsections until every one had been read, and then output them in a pre- determined order. This was because some subsections need to be read first in order to properly dump later subsections. This patch allows them to be dumped in the order they appear.

* [llvm-pdbdump] Improve consistency among subcommands.Zachary Turner2017-06-0816-341/+362
| | | | | | | | | | | | | | | The pdb2yaml and raw subcommands did something very similar but with a different output format, and they used a lot of the same command line options, but each one re-implemented the command line option with slightly different spellings / options. This patch merges them together into a single definition which is shared by both subcommands. This new syntax also allows for more flexibility in the way debug subsections are dumped.

| | | | | | | | | | | | Since D17854 LinkerSubsectionsViaSymbols is unnecessary. It is interfering with ThinLTO implementation of CFI-ICall, where the aliases used on the !LinkerSubsectionsViaSymbols branch are needed to export jump tables to ThinLTO backends.

| | | | | | | | | | | | TerminatorInst subclasses as much as possible now that Value has been de-virtualized These used to be virtual methods that would enable doing the right thing with only a TerminatorInst pointer. I believe they were also acting as vtable anchors in my cases. I think the fact that they had a separate name ending in V was to allow a version without V to be called without a virtual call in a pre-C++11 final keyword world. Where possible the base methods in TerminatorInst dispatch directly to the public methods in the classes that have the same signature. For some classes this wasn't possible so I've left private method versions that match the name and signature of the version in TerminatorInst. All versions have been moved into the class definitions since we no longer need vtable anchors here. Differential Revision: https://reviews.llvm.org/D34011 llvm-svn: 305028

* [clang] Fix format specifiers fixitsAlexander Shaposhnikov2017-06-083-21/+83
| | | | | | | | | | | | | | | | | | | | | | | | | This diff fixes printf "fixits" in the case when there is a wrapping macro and the format string needs multiple replacements. In the presence of a macro there is an extra logic in EditedSource.cpp to handle multiple uses of the same macro argument (see the old comment inside EditedSource::canInsertInOffset) which was mistriggerred when the argument was used only once but required multiple adjustments), as a result the "fixit" was breaking down the format string by dropping the second format specifier, i.e. Log1("test 4: %s %s", getNSInteger(), getNSInteger()) was getting replaced with Log1("test 4: %ld ", (long)getNSInteger(), (long)getNSInteger()) (if one removed the macro and used printf directly it would work fine). In this diff we track the location where the macro argument is used and (as it was before) the modifications originating from all the locations except the first one are rejected, but multiple changes are allowed.

As shown, nothing is expanded for x86 in CGP yet. Also fundamentally, we're doing an IR transform, so we should have IR tests for just that part.
