2015-11-16[Frontend] Rangify for loop. NFC.Vedant Kumar1-2/+2
llvm-svn: 253178
2015-11-05[modules] If we're given a module file, via -fmodule-file=, for a module, butRichard Smith1-4/+24
we can't load that file due to a configuration mismatch, and implicit module building is disabled, and the user turns off the error-by-default warning for that situation, then fall back to textual inclusion for the module rather than giving an error if any of its headers are included. llvm-svn: 252114
2015-11-03Introduce module file extensions to piggy-back data onto module files.Douglas Gregor1-5/+9
Introduce the notion of a module file extension, which introduces additional information into a module file at the time it is built that can then be queried when the module file is read. Module file extensions are identified by a block name (which must be unique to the extension) and can write any bitstream records into their own extension block within the module file. When a module file is loaded, any extension blocks are matched up with module file extension readers, that are per-module-file and are given access to the input bitstream. Note that module file extensions can only be introduced by programmatic clients that have access to the CompilerInvocation. There is only one such extension at the moment, which is used for testing the module file extension harness. As a future direction, one could imagine allowing the plugin mechanism to introduce new module file extensions. llvm-svn: 251955
2015-10-16[modules] Allow the error when explicitly loading an incompatible module fileRichard Smith1-5/+14
via -fmodule-file= to be turned off; in that case, just include the relevant files textually. This allows module files to be unconditionally passed to all compile actions via CXXFLAGS, and to be ignored for rules that specify custom incompatible flags. llvm-svn: 250577
2015-10-05Use llvm::errc instead of std::errc.Rafael Espindola1-1/+1

2015-09-22[CUDA] Allow parsing of host and device code simultaneously.Artem Belevich1-5/+11
* adds -aux-triple option to specify target triple * propagates aux target info to AST context and Preprocessor * pulls in target specific preprocessor macros. * pulls in target-specific builtins from aux target. * sets appropriate host or device attribute on builtins.

2015-09-17createOutputFile should set Error to something if it returns null.Douglas Katzman1-1/+3
This is not portably unit-testable because the only visible effect is a change from one random message string to another. llvm-svn: 247900
2015-08-18Initialize the AST consumer as soon as we have both an ASTConsumer and anRichard Smith1-8/+15
ASTContext. Fixes some cases where we could previously initialize the AST consumer more than once. llvm-svn: 245346

when building with implicit modules disabled. llvm-svn: 245136
2015-08-13Add sanitizer blacklists to the rules generated with -M/-MM/-MD/-MMD.Ivan Krasin1-3/+5
Summary: Clang sanitizers, such as AddressSanitizer, ThreadSanitizer, MemorySanitizer, Control Flow Integrity and others, use blacklists to specify which types / functions should not be instrumented to avoid false positives or suppress known failures. This change adds the blacklist filenames to the list of dependencies of the rules, generated with -M/-MM/-MD/-MMD. This lets CMake/Ninja recognize that certain C/C++/ObjC files need to be recompiled (if a blacklist is updated).

2015-08-09[modules] Don't leak -M flags for dependency file generation into the moduleRichard Smith1-1/+3
build process when we implicitly build a module. Previously, we'd create the specified .d file once for each implicitly-built module and then finally overwrite it with the correct contents after the requested build completes. (This fails if you use stdout as a dependency file, which is what the provided testcase does, and is how I discovered this brokenness.) llvm-svn: 244412
2015-08-09[modules] Attach dependency listeners to the module manager once when it'sRichard Smith1-9/+7
created, rather than creating and attaching a new listener each time we load a module file (yes, the old ones were kept around too!). No functionality change intended, but a bit more sanity. llvm-svn: 244411

2015-07-17Make the clang module container format selectable from the command line.Adrian Prantl1-8/+8
- introduces a new cc1 option -fmodule-format=[raw,obj] with 'raw' being the default - supports arbitrary module container formats that libclang is agnostic to - adds the format to the module hash to avoid collisions - splits the old PCHContainerOperations into PCHContainerWriter and a PCHContainerReader. Thanks to Richard Smith for reviewing this patch! llvm-svn: 242499

2015-06-20Introduce a PCHContainerOperations interface (NFC).Adrian Prantl1-25/+31
A PCHContainerOperations abstract interface provides operations for creating and unwrapping containers for serialized ASTs (precompiled headers and clang modules). The default implementation is RawPCHContainerOperations, which uses a flat file for the output. The main application for this interface will be an ObjectFilePCHContainerOperations implementation that uses LLVM to wrap the module in an ELF/Mach-O/COFF container to store debug info alongside the AST. rdar://problem/20091852 llvm-svn: 240225
2015-05-29Replace push_back(Constructor(foo)) with emplace_back(foo) for non-trivial typesBenjamin Kramer1-3/+2
If the type isn't trivially moveable emplace can skip a potentially expensive move. It also saves a couple of characters. Call sites were found with the ASTMatcher + some semi-automated cleanup. memberCallExpr( argumentCountIs(1), callee(methodDecl(hasName("push_back"))), on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))), hasArgument(0, bindTemporaryExpr( hasType(recordDecl(hasNonTrivialDestructor())), has(constructExpr()))), unless(isInTemplateInstantiation())) No functional change intended. llvm-svn: 238601
2015-05-18[modules] Move implicit creation of ImportDecls for #includes transformed ↵Richard Smith1-19/+0
into module imports from the frontend into Sema where it belongs. llvm-svn: 237555
2015-05-16[modules] Retain the name as written for umbrella headers and directories, ↵Richard Smith1-3/+5
rather than converting to an absolute path. No observable change expected, but this allows us to correctly compute the module for an umbrella header, which later changes will require. llvm-svn: 237508
2015-05-15[modules] Add local submodule visibility support for declarations.Richard Smith1-0/+5
With this change, enabling -fmodules-local-submodule-visibility results in name visibility rules being applied to submodules of the current module in addition to imported modules (that is, names no longer "leak" between submodules of the same top-level module). This also makes it much safer to textually include a non-modular library into a module: each submodule that textually includes that library will get its own "copy" of that library, and so the library becomes visible no matter which including submodule you import. llvm-svn: 237473
2015-05-01[modules] Start moving the module visibility information off the Module itself.Richard Smith1-6/+4
It has no place there; it's not a property of the Module, and it makes restoring the visibility set when we leave a submodule more difficult. llvm-svn: 236300
2015-04-29[modules] Stop trying to fake up a linear MacroDirective history.Richard Smith1-63/+35
Modules builds fundamentally have a non-linear macro history. In the interest of better source fidelity, represent the macro definition information faithfully: we have a linear macro directive history within each module, and at any point we have a unique "latest" local macro directive and a collection of visible imported directives. This also removes the attendent complexity of attempting to create a correct MacroDirective history (which we got wrong in the general case). No functionality change intended. llvm-svn: 236176
2015-04-14Use raw_pwrite_stream in clang.Rafael Espindola1-13/+17
This is a small improvement to -emit-pth and allows llvm to start requiring it. llvm-svn: 234897
2015-04-10[Frontend] Close open file handles before renaming output filesReid Kleckner1-10/+12
The placement of the 'delete' call that was removed in the unique_ptr migration in r234597 was not an accident. The raw_ostream has to be destroyed before you do the rename on Windows, otherwise you get ERROR_ACCESS_DENIED. We can still use unique_ptr, we just need to do a manual reset(). Also, range-for-loop-ify this code. llvm-svn: 234612
2015-04-10Return std::unique_ptr to avoid a release and recreate.Rafael Espindola1-4/+4
llvm-svn: 234598
2015-04-10Use a std::unique_ptr to make it easier to see who owns the stream.Rafael Espindola1-10/+11
llvm-svn: 234597
2015-03-28[Modules] Don't compute a modules cache path if we're not using modules!Chandler Carruth1-1/+2
Notably, this prevents us from doing *tons* of work to compute the modules hash, including trying to read a darwin specific plist file off of the system. There is a lot that needs cleaning up below this layer too. llvm-svn: 233462
2015-03-24[Modules] Stop creating timestamps for the modules cache and trying toChandler Carruth1-3/+4
prune it when we have disabled implicit module generation and thus are not using any cached modules. Also update a test of explicitly generated modules to pass this CC1 flag correctly. This fixes an issue where Clang was dropping files into the source tree while running its tests. llvm-svn: 233117
2015-03-18Remove many superfluous SmallString::str() calls.Yaron Keren1-5/+4
Now that SmallString is a first-class citizen, most SmallString::str() calls are not required. This patch removes a whole bunch of them, yet there are lots more. There are two use cases where str() is really needed: 1) To use one of StringRef member functions which is not available in SmallString. 2) To convert to std::string, as StringRef implicitly converts while SmallString do not. We may wish to change this, but it may introduce ambiguity. llvm-svn: 232622
2015-03-18Make module files passed to a module build via -fmodule-file= available toRichard Smith1-0/+13
consumers of that module. Previously, such a file would only be available if the module happened to actually import something from that module. llvm-svn: 232583
2015-02-28Give better diagnostics when -fmodule-file= finds a bad file: if the file isRichard Smith1-3/+13
found indirectly, explain how we got there, and distinguish between 'file not found' and 'file found but invalid'. llvm-svn: 230839
2015-02-25[modules] Even if we already have a definition of a class, loading in anotherRichard Smith1-1/+4
one can give us more lookup results (due to implicit special members). Be sure to complete the redecl chain for every kind of DeclContext before performing a lookup into it, rather than only doing so for NamespaceDecls. llvm-svn: 230558
2015-02-25[modules] Fix a bug that would result in a build with P paths through a moduleRichard Smith1-0/+3
graph with M modules to take O(P) time, not just O(M) time, when using explicit module builds. llvm-svn: 230412
2015-02-20Add -fno-implicit-modules.Manuel Klimek1-0/+6
If this flag is set, we error out when a module build is required. This is useful in environments where all required modules are passed via -fmodule-file. llvm-svn: 230006
2015-02-19[PCH/Modules] Check that the specific module cache path the PCH was built ↵Argyrios Kyrtzidis1-8/+12
with, is the same as the one in the current compiler invocation. If they differ reject the PCH. This protects against the badness occurring from getting modules loaded from different module caches (see crashes). rdar://19889860 llvm-svn: 229909
2015-02-09Diagnose timeouts in the LockFileManager and delete the dead lock fileBen Langmuir1-2/+12
If the lock file manager times out, we should give an error rather than silently trying to load the existing module. And delete the (presumably) dead lock file, since it will otherwise prevent progress in future invokations. This is unsound since we have no way to prove that the lock file we are deleting is the same one we timed out on, but since the lock is only to avoid excessive rebuilding anyway it should be okay. Depends on llvm r228603. llvm-svn: 228604
2015-02-04[modules] When using -E, we may try to merge decls despite having no SemaRichard Smith1-14/+13
object. In such a case, use the TU's DC for merging global decls rather than giving up when we find there is no TU scope. Ultimately, we should probably avoid all loading of decls when preprocessing, but there are other reasonable use cases for loading an AST file with no Sema object for which this is the right thing. llvm-svn: 228234
