2012-06-20Remove a 'static' specifier from an 'inline' function in a header file.Chandler Carruth
This issue was caught by the new '-Winternal-linkage-in-inline' warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158801 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Revert "Provide a -no-pedantic to cancel out -pedantic." This needs to be ↵Ted Kremenek
designed a bit further. We may wish to just have -Wno flags to silence warnings, and not have a -no-pedantic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158796 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Add the PCH file name to the message about not being able to read the PCH.Kaelyn Uhrain
Also add a couple of unit tests to check the invalid-PCH error messages to satisfy PR4568 and for the assertion (introduced in r149918 and fixed in r158769) that would cause clang to crash when given an empty PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158772 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Reapply r158700 and fixup patches, minus one hunk that slipped through andSean Hunt
caused a crash in an obscure case. On the plus side, it caused me to catch another bug by inspection. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158767 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Extend the support for cl-std to include 1.2.Tanya Lattner
Add error checking for the static qualifier which is now allowed in certain situations for OpenCL 1.2. Use the CL version to turn on this feature. Added test case for 1.2 static storage class feature. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158759 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Reapplying the changes from r158717 as they were rolled back to avoid merge ↵Aaron Ballman
conflicts from a separate problematic patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158750 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Revert r158700 and dependent patches r158716, r158717, and r158731.Jakob Stoklund Olesen
The original r158700 caused crashes in the gcc test suite, g++.abi/vtable3a.C among others. It also caused failures in the libc++ test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158749 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Revert predefined decl tracking.Meador Inge
r158085 added some logic to track predefined declarations. The main reason we had predefined declarations in the input was because the __builtin_va_list declarations were injected into the preprocessor input. As of r158592 we explicitly build the __builtin_va_list declarations. Therefore the predefined decl tracking is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158732 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Improves parsing and semantic analysis for MS __declspec attributes. This ↵Aaron Ballman
includes support for the align (which fixes PR12631). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158717 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Improve the specification of spellings in Attr.td.Sean Hunt
Note that this is mostly a structural patch that handles the change from the old spelling style to the new one. One consequence of this is that all AT_foo_bar enum values have changed to not be based off of the first spelling, but rather off of the class name, so they are now AT_FooBar and the like (a straw poll on IRC showed support for this). Apologies for code churn. Most attributes have GNU spellings as a temporary solution until everything else is sorted out (such as a Keyword spelling, which I intend to add if someone else doesn't beat me to it). This is definitely a WIP. I've also killed BaseCheckAttr since it was unused, and I had to go through every attribute anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158700 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Add a -fuse-init-array option to cc1 and map to the UseInitArray targetRafael Espindola
option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158694 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Improve the error message when a function overload candidate is rejectedKaelyn Uhrain
because it expects a reference and receives a non-l-value. For example, given: int foo(int &); template<int x> void b() { foo(x); } clang will now print "expects an l-value for 1st argument" instead of "no known conversion from 'int' to 'int &' for 1st argument". The change in wording (and associated code to detect the case) was prompted by comment #5 in PR3104, and should be the last bit of work needed for the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158691 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-18Change -Winternal-linkage-in-inline from ExtWarn to Warning in C++.Jordan Rose
Per post-commit review, it's not appropriate to use ExtWarn in C++, because we can't prove that the inline function will actually be defined in more than one place (and thus we can't prove that this violates the ODR). This removes the warning entirely from uses in the main source file in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158689 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-18Support -Winternal-linkage-in-inline in C++ code.Jordan Rose
This includes treating anonymous namespaces like internal linkage, and allowing const variables to be used even if internal. The whole thing's been broken out into a separate function to avoid nested ifs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158683 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-18Move a few static functions from DiagnosticRenderer.cpp into SourceManager.Matt Beaumont-Gay
This simplifies the code a little bit, since these functions all took a SourceManager parameter and called a bunch of methods on it, and makes the functions available to other users. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158676 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-18Documentation cleanup:James Dennett
* Escaped "::" where needed to prevent Doxygen trying to make links; * Updated one mention of C++0x to refer to C++11; * Fixed a \brief summary to make it somewhat concise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158667 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-18Allow internal decls in inline functions if the function is in the main file.Jordan Rose
This handles the very common case of people writing inline functions in their main source files and not tagging them as inline. These cases should still behave as the user intended. (The diagnostic is still emitted as an extension.) I'm reworking this code anyway to account for C++'s equivalent restriction in [basic.def.odr]p6, but this should get some bots back to green. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158666 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-18alloc_size attribute: there's nothing wrong with alloc_size(1,1). It just ↵Nuno Lopes

2012-06-18Handle C++11 attribute namespaces automatically.Sean Hunt
Now, as long as the 'Namespaces' variable is correct inside Attr.td, the generated code will correctly admit a C++11 attribute only when it has the appropriate namespace(s). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158661 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-17Switch users of SmallMap to use SmallDenseMap instead.Chandler Carruth
The most important change here is that the destructor and copy constructor for StoredDeclsList will now reliably be run. Previously, the destructors at least were missed in some cases. See the LLVM commits discussions for why SmallMap is broken and going away. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158642 91177308-0d34-0410-b5e6-96231b3b80d8
