* [llvm-readobj] Print MIPS .MIPS.options section contentSimon Atanasyan2016-05-045-7/+80
| | | | | | | | | .MIPS.options section specifies miscellaneous options to be applied to an object file. LLVM as well as modern versions of GNU tools emit the only type of the options - ODK_REGINFO. The patch teaches llvm-readobj to print details of the ODK_REGINFO and skip contents of other options. llvm-svn: 268478

* Add a way for an ObjectFile to indicate that assembly emulationJason Molenda2016-05-046-3/+71
| | | | | | | | | | | | | | | | | | | | | should not be used for this module -- for use when an ObjectFile knows that it does not have meaningful or accurate function start addresses. More commonly, it is not clear that function start addresses are missing in a module. There are certain cases on Mac OS X where we can tell that a Mach-O binary has been stripped of this essential information, and the unwinder can end up emulating many megabytes of instructions for a single "function" in the binary. When a Mach-O binary is missing both an LC_FUNCTION_STARTS load command (very unusual) and an eh_frame section, then we will assume it has also been stripped of symbols and that instruction emulation will not be useful on this module. <rdar://problem/25988067> llvm-svn: 268475

* Fix CodeCompletion & TypoCorrection when combining a PCH with ModulesBen Langmuir2016-05-048-12/+109
| | | | | | | | | | | | | | This commit fixes the IdentifierIterator to actually include identifiers from a PCH or precompiled preamble when there is also a global module index. This was causing code-completion (outside of C++) and typo-correction to be missing global identifiers defined in the PCH/preamble. Typo-correction has been broken since we first started using the module index, whereas code-completion only started relying on identifier iterator in r232793. rdar://problem/25642879 llvm-svn: 268471
* [X86] Lower zext i1 argumentsDavid Majnemer2016-05-042-0/+57
| | | | | | | | | | | | | i1 is now a legal type for X86 with AVX512. There were some paths in X86FastISel which were not quite ready to see an i1 value: they were not quite sure how to deal with sign/zero extends for call arguments. DTRT by extending to i8 for zeroext and bailing out of FastISel for signext. This fixes PR27591. llvm-svn: 268470

* Produce another specific error message for a malformed Mach-O file when a loadKevin Enderby2016-05-035-8/+11
| | | | | | | | | | | | | | | | command has a size less than 8 bytes. I think the existing test case in test/Object/macho-invalid.test for macho64-invalid-too-small-load-command was trying to test for this but that test case triggered a different error given how it was constructed. So I constructed a new test case that would trigger this specific error. I also changed the error message to be consistent with the other malformed Mach-O file error messages. I also removed object_error::macho_small_load_command from Object/Error.h as it is not needed and can just use object_error::parse_failed and let the error message string distinguish the error. llvm-svn: 268463

* [modules][debuginfo] Only include imported modules when targeting LLDBDavid Blaikie2016-05-036-5/+20
| | | | | | | | | | | | | | | | | These constructs are only applicable to a debugger capable of loading a Clang AST, so omit them for brevity when not doing so. We could potentially propagate more of CodeGenOptions through the ObjectFilePCGContainerOperations for consistency (so the next person who adds some CodeGenOpts feature that tweaks debug info output doesn't get caught by this), so I'm open to objections/alternatives there, but went with this for now. Tested just a couple of basic cases (one direct, one indirect (through the ObjectFilePCHContainerOperations) & fixed up other cases to pass the -debugger-tuning flag as appropriate. llvm-svn: 268460

| | | | | | | | | | | | | Ability to parse codeview type streams is also needed by DebugInfoPDB for parsing PDBs, so moving this into a library gives us this option. Since DebugInfoPDB had already hand rolled some code to do this, that code is now convereted over to using this common abstraction.

| | | | | | | | | | | A loop pass that didn't preserve this entire set of passes wouldn't play well with other loop passes, since these are generally a basic requirement to do any interesting transformations to a loop. Adds a helper to get the set of analyses a loop pass should preserve, and checks that any loop pass we run satisfies the requirement. llvm-svn: 268444
* Create new library 'libc++experimental.a' for packaging TS symbols.Eric Fiselier2016-05-036-3/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Out-of-line symbols for <experimental/...> headers are not ABI or API stable and cannot live in the 'libc++.dylib'. Currently they have nowhere to live. I would like to add a new library target `libc++experimental.a` to fix this. Previously I had suggested different libraries for different TS's (`libc++filesystem.a`, 'libc++LFTS.a`, ect). I no longer think this is the right approach. Instead `c++experimental` will hold *all* TS implementations as a single monolithic library. I see two main benefits to this: 1. Users only have to know about and manually link one library. 2. It makes it easy to implement TS's with one or two out-of-line symbols. (Ex. PMRs) `c++experimental` provides NO ABI compatibility. Symbols can freely be added/removed/changed without concern for ABI stability. I will add documentation for this after landing this patch (but before adding anything to it). `c++experimental` only builds as a static library. By default CMake will build/test this library but will *NOT* install it. This patch adds the CMake and LIT logic needed to build/test the new library. Once this lands I plan on using it to implement parts of `<experimental/memory_resource>`.

* [clang-tidy] Speedup misc-static-assert.Samuel Benzaquen2016-05-031-3/+7
| | | | | | | | | | | | | | | | | | | Summary: Speedup the misc-static-assert check by not use `stmt()` as the toplevel matcher. The framework runs a filter on the matchers before trying them on each node and uses the toplevel type for this. Using `stmt()` as the toplevel causes the matcher to be run on every `Stmt` node, even if the node doesn't match the desired types. This change speeds up clang-tidy by ~5% in a benchmark.

* [CMake] NFC. Add support for testing the compiler without testing the linkerChris Bieneman2016-05-033-13/+81
| | | | | | | | | | | | | | | | | | | Summary: One of the big limitations we have in the compiler-rt build system today is that we cannot bootstrap building the builtins because you need a fully functional toolchain to pass CMake's tests.
