* Enable C++2a Chrono LiteralsErich Keane2018-07-191-3/+8
| | | | | | | | | | | | | | | | | | | C++2a via http://wg21.link/p0355 permits the library literals of 'd' and 'y'. This patch enables them in the Lexer so that they can be properly parsed. Note that 'd' gets confused with the hex character, so modifications to how octal, binary, and decimal numbers are parsed were required. Since this is simply making previously invalid code legal, this should be fine. Hex still greedily parses the 'd' as a hexit, since it would a: violate [lex.ext]p1 b: break existing code.

* [Fixed Point Arithmetic] Fix for bug where integer literals could be treated ↵Leonard Chan2018-07-171-5/+10
| | | | | | | | | | | | | | | | as fixed point literals This addresses a bug brought up in https://bugs.llvm.org/show_bug.cgi?id=38161 where integer literals could be treated as fixed point types and throw errors related to fixed point types when the 'k' or 'r' suffix used. The fix also addresses the second issue brought up with the assertion by not treating integers as fixed point types in the first place. Integers that have suffixes 'k' and 'r' now throw the error `invalid suffix 'k/r' on integer constant`. A few more tests were also added to ensure that fixed point types, and any errors/warnings related to them, are limited to C for now. Prior discussion also at https://reviews.llvm.org/D46915.

| | | | | | | | | | | | | | | | | As listed in the above PRs, vector_size doesn't allow dependent types/values. This patch introduces a new DependentVectorType to handle a VectorType that has a dependent size or type. In the future, ALL the vector-types should be able to create one of these to handle dependent types/sizes as well. For example, DependentSizedExtVectorType could likely be switched to just use this instead, though that is left as an exercise for the future.

* [clang-cl, PCH] Implement support for MS-style PCH through headersErich Keane2018-07-053-3/+130
| | | | | | | | | | | | | | | | | | | | | Implement support for MS-style PCH through headers. This enables support for /Yc and /Yu where the through header is either on the command line or included in the source. It replaces the current support the requires the header also be specified with /FI. This change adds a -cc1 option -pch-through-header that is used to either start or stop compilation during PCH create or use. When creating a PCH, the compilation ends after compilation of the through header. When using a PCH, tokens are skipped until after the through header is seen.

* Warning for framework include violation from Headers to PrivateHeadersBruno Cardoso Lopes2018-06-251-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | Framework vendors usually layout their framework headers in the following way: Foo.framework/Headers -> "public" headers Foo.framework/PrivateHeader -> "private" headers Since both headers in both directories can be found with #import <Foo/some-header.h>, it's easy to make mistakes and include headers in Foo.framework/PrivateHeader from headers in Foo.framework/Headers, which usually configures a layering violation on Darwin ecosystems. One of the problem this causes is dep cycles when modules are used, since it's very common for "private" modules to include from the "public" ones; adding an edge the other way around will trigger cycles. Add a warning to catch those cases such that: ./A.framework/Headers/A.h:1:10: warning: public framework header includes private framework header 'A/APriv.h' #include <A/APriv.h> ^ rdar://problem/38712182 llvm-svn: 335542

| | | | | | | | | | | | | | | When a module declaration for a framework lacks the 'framework' qualifier, the listed headers aren't found (because there's no trigger for the special framework style path lookup) and the module is silently not built.

* PR37189 Fix incorrect end source location and spelling for a split '>>' token.Richard Smith2018-04-305-19/+31
| | | | | | | | | | | | | | | | | | When a '>>' token is split into two '>' tokens (in C++11 onwards), or (as an extension) when we do the same for other tokens starting with a '>', we can't just use a location pointing to the first '>' as the location of the split token, because that would result in our miscomputing the length and spelling for the token. As a consequence, for example, a refactoring replacing 'A<X>' with something else would sometimes replace one character too many, and similarly diagnostics highlighting a template-id source range would highlight one character too many. Fix this by creating an expansion range covering the first character of the '>>' token, whose spelling is '>'. For this to work, we generalize the expansion range of a macro FileID to be either a token range (the common case) or a character range (used in this new case). llvm-svn: 331155

Since completion is often ran on incomplete identifiers, they may turn into keywords by accident. For example, we should produce same results for all of these completion points: // ^ is completion point. ^class cla^ss class^ Previously clang produced different results for the last case (as if the completion point was after a space: `class ^`). This change also updates some offsets in tests that (unintentionally?) relied on the old behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | usual allocation/deallocation functions. Summary: Libc++'s default allocator uses `__builtin_operator_new` and `__builtin_operator_delete` in order to allow the calls to new/delete to be ellided. However, libc++ now needs to support over-aligned types in the default allocator. In order to support this without disabling the existing optimization Clang needs to support calling the aligned new overloads from the builtins. See llvm.org/PR22634 for more information about the libc++ bug. This patch changes `__builtin_operator_new`/`__builtin_operator_delete` to call any usual `operator new`/`operator delete` function. It does this by performing overload resolution with the arguments passed to the builtin to determine which allocation function to call. If the selected function is not a usual allocation function a diagnostic is issued. One open issue is if the `align_val_t` overloads should be considered "usual" when `LangOpts::AlignedAllocation` is disabled. In order to allow libc++ to detect this new behavior the value for `__has_builtin(__builtin_operator_new)` has been updated to `201802`.

This patch lifts that restriction. Special functions for non-trivial C structs are synthesized that are needed to default-initialize, copy/move, and destroy the structs and manage the ownership of the objects the __strong pointer fields point to.

| | | | | | | | | | All use declarations need to be directly placed in the top-level module anyway, knowing the submodule doesn't really help. The header that has the offending #include can easily be seen in the diagnostics source location. Review: https://reviews.llvm.org/D43673 llvm-svn: 326023
* Clean up use of C allocation functionsSerge Pavlov2018-02-211-1/+2
| | | | | | | | | | | | | | | | If the value returned by `malloc`, `calloc` or `realloc` is not checked for null pointer, this change replaces them for `safe_malloc`, `safe_calloc` or `safe_realloc`, which are defined in the namespace `llvm`. These function report fatal error on out of memory. In the plain C files, assertion statements are added to ensure that memory is successfully allocated. The aim of this change is to get better diagnostics of OOM on Windows. Differential Revision: https://reviews.llvm.org/D43017 llvm-svn: 325661
* [Modules] Extend -fmodule-name semantic for frameworks with private modulesBruno Cardoso Lopes2018-02-161-4/+22
| | | | | | | | | | | | | Assume Foo.framework with two module maps and two modules Foo and Foo_Private. Framework authors need to skip building both Foo and Foo_Private when using -fmodule-name=Foo, since both are part of the framework and used interchangeably during compilation. rdar://problem/37500098 llvm-svn: 325305
* [modules] Fix incorrect diagnostic mapping computation when a module changesRichard Smith2018-02-091-0/+14
| | | | | | | | | | | | | | | diagnostic settings using _Pragma within a macro. The AST writer had previously been assuming that all diagnostic state transitions would occur within a FileID corresponding to a file. When a diagnostic state change occured within a macro, it was unable to form a location for that state change and would instead corrupt the diagnostic state of the "root" node (and thus that of the main compilation). Also introduce a "#pragma clang __debug diag_mapping" debugging utility that I added to track this issue down. llvm-svn: 324695
* [Lex] Fix handling numerical literals ending with ' and signed exponent.Volodymyr Sapsai2018-02-061-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | For input `0'e+1` lexer tokenized as numeric constant only `0'e`. Later NumericLiteralParser skipped 0 and ' as digits and parsed `e+1` as valid exponent going past the end of the token. Because it didn't mark numeric literal as having an error, it continued parsing and tried to expandUCNs with StringRef of length -2. The fix is not to parse exponent when we reached the end of token.
