* PR13657 (and duplicates):Richard Smith2013-09-125-92/+602
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a comma occurs in a default argument or default initializer within a class, disambiguate whether it is part of the initializer or whether it ends the initializer. The way this works (which I will be proposing for standardization) is to treat the comma as ending the default argument or default initializer if the following token sequence matches the syntactic constraints of a parameter-declaration-clause or init-declarator-list (respectively). This is both consistent with the disambiguation rules elsewhere (where entities are treated as declarations if they can be), and should have no regressions over our old behavior. I think it might also disambiguate all cases correctly, but I don't have a proof of that. There is an annoyance here: because we're performing a tentative parse in a situation where we may not have seen declarations of all relevant entities (if the comma is part of the initializer, lookup may find entites declared later in the class), we need to turn off typo-correction and diagnostics during the tentative parse, and in the rare case that we decide the comma is part of the initializer, we need to revert all token annotations we performed while disambiguating. Any diagnostics that occur outside of the immediate context of the tentative parse (for instance, if we trigger the implicit instantiation of a class template) are *not* suppressed, mirroring the usual rules for a SFINAE context. llvm-svn: 190639

* Move the execution code from Compilation::ExecuteCommand to Command::ExecuteHans Wennborg2013-09-122-11/+15
| | | | | | | | | | | | | | I think it makes sense that a Command knows how to execute itself. There's no functionality change but i rewrote the code to avoid the manual memory management of Argv. My motivation for this is that I plan to subclass Command to build fall-back functionality into clang-cl. Differential Revision: http://llvm-reviews.chandlerc.com/D1654 llvm-svn: 190621
* Move Compilation::PrintJob and PrintDiagnosticJob into Job::Print.Hans Wennborg2013-09-125-141/+106
| | | | | | | | | | | | | | | | | This moves the code to Job.cpp, which seems like a more natural fit, and replaces the "is this a JobList? is this a Command?" logic with a virtual function call. It also removes the code duplication between PrintJob and PrintDiagnosticJob and simplifies the code a little. There's no functionality change here, except that the Executable is now always printed within quotes, whereas it would previously not be quoted in crash reports, which I think was a bug.

* [CMake] Put controversial always-recheck-revision-number behind an option.Jordan Rose2013-09-121-2/+8
| | | | | | | | | | | | | | | CMake does not have the ability to perform actions before calculating dependencies, so it can't know whether it needs to rebuild clangBasic to update for a new revision number. CLANG_ALWAYS_CHECK_VC_REV (off by default) will cause clangBasic to always be dirty by deleting the generated SVNVersion.inc after use; otherwise, SVNVersion.inc will always be updated, but only included in the final binary when clangBasic is rebuilt. It'd be great to find a better way to do this, but hopefully this is still an improvement over the complete lack of version information before. llvm-svn: 190613

* [CMake] Always include the Clang repo version, just like the autoconf build.Jordan Rose2013-09-111-30/+20
| | | | | | | | | | | | | Now that LLVM's helper script GetSVN.cmake actually works consistently, there's no reason not to use it. This does mean that the clangBasic target is potentially always dirty, because CMake-generated projects do not necessarily recalculate dependencies after running each target. This should end the issues of the AST format changing and breaking old module files; CMake-Clang should now detect that the version changed just like Autoconf-Clang has. llvm-svn: 190557

* [analyzer] Handle zeroing constructors for fields of structs with empty bases.Jordan Rose2013-09-111-4/+13
| | | | | | | | | | | | | | | | | | | RegionStore tries to protect against accidentally initializing the same region twice, but it doesn't take subregions into account very well. If the outer region being initialized is a struct with an empty base class, the offset of the first field in the struct will be 0. When we initialize the base class, we may invalidate the contents of the struct by providing a default value of Unknown (or some new symbol). We then go to initialize the member with a zeroing constructor, only to find that the region at that offset in the struct already has a value. The best we can do here is to invalidate that value and continue; neither the old default value nor the new 0 is correct for the entire struct after the member constructor call. The correct solution for this is to track region extents in the store. <rdar://problem/14914316> llvm-svn: 190530

| | | | | | | | | | | With r190382, -Wunused-variable warns about unused const variables when appropriate. For codebases that use -Werror, this poses a problem as existing unused const variables need to be cleaned up first.

* Support for modular module-map-filesDaniel Jasper2013-09-111-2/+57
| | | | | | | | | | | | | | | | | | | This patch is the first step to make module-map-files modular (instead of requiring a single "module.map"-file per include directory). This step adds a new "extern module" declaration that enables module-map-files to reference one another along with a very basic implementation. The next steps are: * Combine this with the use-declaration (from http://llvm-reviews.chandlerc.com/D1546) in order to only load module map files required for a specific compilation. * Add an additional flag to start with a specific module-map-file (instead of requiring there to be at least one "module.map").

* Add -fansi-escape-codes optionNico Rieck2013-09-112-0/+6
| | | | | | | | | | | | | Some build systems use pipes for stdin/stderr. On nix-ish platforms colored output can be forced by -fcolor-diagnostics. On Windows this option has no effect in these cases because LLVM uses the console API (which only operates on the console buffer) even if a console wrapper capable of interpreting ANSI escape codes is used. The -fansi-escape-codes option allows switching from the console API to ANSI escape codes. It has no effect on other platforms. llvm-svn: 190464

* [ms-cxxabi] Implement guard variables for static initializationReid Kleckner2013-09-1014-34/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | Static locals requiring initialization are not thread safe on Windows. Unfortunately, it's possible to create static locals that are actually externally visible with inline functions and templates. As a result, we have to implement an initialization guard scheme that is compatible with TUs built by MSVC, which makes thread safety prohibitively difficult. MSVC's scheme is that every function that requires a guard gets an i32 bitfield. Each static local is assigned a bit that indicates if it has been initialized, up to 32 bits, at which point a new bitfield is created. MSVC rejects inline functions with more than 32 static locals, and the externally visible mangling (?_B) only allows for one guard variable per function. On Eli's recommendation, I used MangleNumberingContext to track which bit each static corresponds to. Implements PR16888.
