* [clang][NFC] Consolidating usage of "FinalPhase" in Driver::BuildActions.Puyan Lotfi2019-08-091-83/+100
| | | | | | | | | | | | | | I am working to remove this concept of the "FinalPhase" in the clang driver, but it is used in a lot of different places to do argument handling for different combinations of phase pipelines and arguments. I am trying to consolidate most of the uses of "FinalPhase" into its own separate scope. Eventually, in a subsequent patch I will move all of this stuff to a separate function, and have more of the complication phase list construction setup into types::getComplicationPhases.

| | | | | | | | | | | | | | | | Summary: A condition could be a multi-line expression where we create the highlight in separated chunks. PathDiagnosticPopUpPiece is not made for that purpose, it cannot be added to multiple lines because we have only one ending part which contains all the notes. So that it cannot have multiple endings and therefore this patch narrows down the ranges of the highlight to the given interesting variable of the condition. It prevents HTML-breaking injections.

* clang: Diag running out of file handles while looking for filesNico Weber2019-08-081-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | clang would only print "file not found" when it's unable to find a header file. If the reason for that is a file handle leak, that's not a very useful error message. For errors that aren't in a small whitelist ("file not found", "file is directory"), print an error with the strerror() output. This changes behavior in corner cases: If clang was out of file handles while looking in one -I dir but then suddenly wasn't when looking in the next -I dir, and both directories contained a file with the desired name, previously we'd silently return the file from the second directory. For this reason, it's important to ignore "is a directory" for this new diag: if a file foo/foo exists and -I -Ifoo are passed, an include of "foo" should successfully open file "foo" in directory "foo/" instead of complaining that "./foo" is a directory. No test since we mostly hit this when there's a handle leak somewhere, and currently there isn't one. I manually tested this with the repro steps in comment 2 on the bug below. Fixes PR42524.

* hwasan: Instrument globals.Peter Collingbourne2019-08-061-0/+5
| | | | | | | | | | | | | | | | | | Globals are instrumented by adding a pointer tag to their symbol values and emitting metadata into a special section that allows the runtime to tag their memory when the library is loaded. Due to order of initialization issues explained in more detail in the comments, shadow initialization cannot happen during regular global initialization. Instead, the location of the global section is marked using an ELF note, and we require libc support for calling a function provided by the HWASAN runtime when libraries are loaded and unloaded.

* [clang-scan-deps] Implementation of dependency scanner over minimized sourcesAlex Lorenz2019-08-064-13/+279
| | | | | | | | | | | | | | | | | | | This commit implements the fast dependency scanning mode in clang-scan-deps: the preprocessing is done on files that are minimized using the dependency directives source minimizer. A shared file system cache is used to ensure that the file system requests and source minimization is performed only once. The cache assumes that the underlying filesystem won't change during the course of the scan (or if it will, it will not affect the output), and it can't be evicted. This means that the service and workers can be used for a single run of a dependency scanner, and can't be reused across multiple, incremental runs. This is something that we'll most likely support in the future though. Note that the driver still utilizes the underlying real filesystem. This commit is also still missing the fast skipped PP block skipping optimization that I mentioned at EuroLLVM talk. Additionally, the file manager is still not reused by the threads as well.

* [Driver] Introduce -stdlib++-isystemShoaib Meenai2019-08-062-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are times when we wish to explicitly control the C++ standard library search paths used by the driver. For example, when we're building against the Android NDK, we might want to use the NDK's C++ headers (which have a custom inline namespace) even if we have C++ headers installed next to the driver. We might also be building against a non-standard directory layout and wanting to specify the C++ standard library include directories explicitly. We could accomplish this by passing -nostdinc++ and adding an explicit -isystem for our custom search directories. However, users of our toolchain may themselves want to use -nostdinc++ and a custom C++ search path (libc++'s build does this, for example), and our added -isystem won't respect the -nostdinc++, leading to multiple C++ header directories on the search path, which causes build failures. Add a new driver option -stdlib++-isystem to support this use case. Passing this option suppresses adding the default C++ library include paths in the driver, and it also respects -nostdinc++ to allow users to still override the C++ library paths themselves. It's a bit unfortunate that we end up with both -stdlib++-isystem and -cxx-isystem, but their semantics differ significantly. -cxx-isystem is unaffected by -nostdinc++ and is added to the end of the search path (which is not appropriate for C++ standard library headers, since they often #include_next into other system headers), while -stdlib++-isystem respects -nostdinc++, is added to the beginning of the search path, and suppresses the default C++ library include paths.

* [Driver] Prioritize SYSROOT/usr/include over RESOURCE_DIR/include on linux-muslFangrui Song2019-08-061-5/+8

Reorder RESOURCE_DIR/include to fix the search order problem. (Currently musl doesn't provide stdatomic.h. stdatomic.h is still found in RESOURCE_DIR/include.) gcc on musl has a similar search order: ``` /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/../../../../include/c++/8.3.0 /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/../../../../include/c++/8.3.0/x86_64-alpine-linux-musl /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/../../../../include/c++/8.3.0/backward /usr/local/include /usr/include/fortify /usr/include /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/include ``` This is different from a glibc-based distribution where RESOURCE_DIR/include is placed before SYSROOT/usr/include. According to the maintainer of musl: > musl does not support use/mixing of compiler-provided std headers with its headers, and intentionally has no mechanism for communicating with such headers as to which types have already been defined or still need to be defined. If the current include order, with clang's headers before the libc ones, works in some situations, it's only by accident.

* [clang][DirectoryWatcher] Adding llvm::Expected error handling to create.Puyan Lotfi2019-08-063-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch Unix style errno error reporting from the inotify layer was used by DirectoryWatcher::create to simply return a nullptr on error. This would generally be ok, except that in LLVM we have much more robust error reporting through the facilities of llvm::Expected. The other critical thing I stumbled across was that the unit tests for DirectoryWatcher were not failing abruptly when inotify_init() was reporting an error, but would continue with the testing and eventually hit a deadlock in a pathological machine state (ie in the unit test, the return nullptr on ::create was ignored). Generally this pathological state never happens on any build bot, so it is totally understandable that it was overlooked, but on a Linux desktop running a dubious desktop environment (which I will not name) there is a chance that said desktop environment could use up enough inotify instances to exceed the user's limit. These are the conditions that led me to hit the deadlock I am addressing in this patch with more robust error handling. With the new llvm::Expected error handling when your system runs out of inotify instances for your user, the unit test will be forced to handle the error or crash and report the issue to the user instead of weirdly deadlocking on a condition variable wait.

If x is subnormal: o For SUSv3-conforming applications compiled with the c99 com- piler driver (see standards(7)), the exponent of x as if x were normalized is returned. o Otherwise, if compiled with the cc compiler driver, -1022, -126, and -16382 are returned for logb(), logbf(), and logbl(), respectively.

It moves LangStandard* and InputKind::Language to Basic. It is mostly mechanical, with only a few changes of note: - enum Language has been changed into enum class Language : uint8_t to avoid a clash between OpenCL in enum Language and OpenCL in enum LangFeatures and not to increase the size of class InputKind. - Now that getLangStandardForName, which is currently unused, also checks both canonical and alias names, I've introduced a helper getLangKind which factors out a code pattern already used 3 times. The patch has been tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu. There's a companion patch for lldb which uses LangStandard.h (https://reviews.llvm.org/D65717).
