2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99. This reverts commit 7af19b817ba964ac560b50c1ed6183235f699789. This reverts commit fdd15602a42bbe26185978ef1e17019f6d969aa7. This reverts commit 00bd44d5677783527d7517c1ffe45e4d75a0f56f.

2012-02-02Back out my heinous hack that tricked the module generation mechanismDouglas Gregor
into using non-absolute system includes (<foo>)... ... and introduce another hack that is simultaneously more heineous and more effective. We whitelist Clang-supplied headers that augment or override system headers (such as float.h, stdarg.h, and tgmath.h). For these headers, Clang does not provide a module mapping. Instead, a system-supplied module map can refer to these headers in a system module, and Clang will look both in its own include directory and wherever the system-supplied module map suggests, then adds either or both headers. The end result is that Clang-supplied headers get merged into the system-supplied module for the C standard library. As a drive-by, fix up a few dependencies in the _Builtin_instrinsics module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149611 91177308-0d34-0410-b5e6-96231b3b80d8

__has_builtin in an empty file, as we were overwriting the EOF token. Overwriting an arbitrary token never seems like a good idea in the error case. This fixes a bug reported on the GCC list :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149397 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-29Rework HeaderSearch's interface for getting a module from a name andDouglas Gregor
for getting the name of the module file, unifying the code for searching for a module with a given name (into lookupModule()) and separating out the mapping to a module file (into getModuleFileName()). No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149197 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-27Introduce module attributes into the module map grammar, along with aDouglas Gregor
single attribute ("system") that allows us to mark a module as being a "system" module. Each of the headers that makes up a system module is considered to be a system header, so that we (for example) suppress warnings there. If a module is being inferred for a framework, and that framework directory is within a system frameworks directory, infer it as a system framework. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149143 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-24Only mark an IdentifierInfo as having changed since deserializationDouglas Gregor
when it actually has changed (and not, e.g., when we've simply attached a deserialized macro definition). Good for ~1.5% reduction in module file size, mostly in the identifier table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148808 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-23Improve Lexer::getImmediateMacroName to take into account inner macrosArgyrios Kyrtzidis
of macro arguments. For "MAC1( MAC2(foo) )" and location of 'foo' token it would return "MAC1" instead of "MAC2". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148704 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Improves support for Unicode in character literalsSeth Cantrell
Updates ProcessUCNExcape() for C++. C++11 allows UCNs in character and string literals that represent control characters and basic source characters. Also C++03 allows UCNs that refer to surrogate codepoints. UTF-8 sequences in character literals are now handled as single c-chars. Added error for multiple characters in Unicode character literals. Added errors for when a the execution charset encoding of a c-char cannot be represented as a single code unit in the associated character type. Note that for the purposes of this error the asso- ciated character type for a narrow character literal is char, not int, even though in C narrow character literals have type int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148389 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-16Some improvements to the handling of C11 atomic types:David Chisnall
- Add atomic-to/from-nonatomic cast types - Emit atomic operations for arithmetic on atomic types - Emit non-atomic stores for initialisation of atomic types, but atomic stores and loads for every other store / load - Add a __atomic_init() intrinsic which does a non-atomic store to an _Atomic() type. This is needed for the corresponding C11 stdatomic.h function. - Enables the relevant __has_feature() checks. The feature isn't 100% complete yet, but it's done enough that we want people testing it. Still to do: - Make the arithmetic operations on atomic types (e.g. Atomic(int) foo = 1; foo++;) use the correct LLVM intrinsic if one exists, not a loop with a cmpxchg. - Add a signal fence builtin - Properly set the fenv state in atomic operations on floating point values - Correctly handle things like _Atomic(_Complex double) which are too large for an atomic cmpxchg on some platforms (this requires working out what 'correctly' means in this context) - Fix the many remaining corner cases git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148242 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-15Two variables had been added for an assert, but their values wereChandler Carruth

2012-01-13When inferring a module for a framework, first determine whether thatDouglas Gregor
framework is actually a subframework within a top-level framework. If so, only infer a module for the top-level framework and then dig out the appropriate submodule. This helps us cope with an amusing subframeworks anti-pattern, where one uses -F <framework>/Frameworks to get direct include access to the subframeworks of a framework (which otherwise would not be permitted). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148148 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-13When inferring a module map for a framework, add the 'private'Douglas Gregor
requirement to headers under PrivateHeaders. We don't want to build them as part of the module (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148082 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-06When inferring a submodule ID during module creation, look up theDouglas Gregor
include stack to find the first file that is known to be part of the module. This copes with situations where the module map doesn't completely specify all of the headers that are involved in the module, which can come up when there are very strange #include_next chains (e.g., with weird compiler/stdlib headers like stdarg.h or float.h). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147662 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-04Store the submodules of a module in source order, as they are storedDouglas Gregor
in the module map. This provides a bit more predictability for the user, as well as eliminating the need to sort the submodules when serializing them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147564 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-04Add __has_feature(modules) to indicate when modules are available (inDouglas Gregor
any language variant), and restrict __has_feature(objc_modules) to mean that we also have the Objective-C @import syntax. I anticipate __has_feature(cxx_modules) and/or __has_feature(c_modules) for when we nail down the module syntax for C/C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147548 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-03Eliminate the uglified keyword __import_module__ for importingDouglas Gregor
modules. This leaves us without an explicit syntax for importing modules in C/C++, because such a syntax needs to be discussed first. In Objective-C/Objective-C++, the @import syntax is used to import modules. Note that, under -fmodules, C/C++ programs can import modules via the #include mechanism when a module map is in place for that header. This allows us to work with modules in C/C++ without committing to a syntax. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147467 91177308-0d34-0410-b5e6-96231b3b80d8
