2012-10-30In the past "production" clang builds would not be used for c++, andRafael Espindola
we had the -ccc-clang-cxx and -ccc-no-clang-cxx options to force them on or off for testing. Clang c++ support is now production quality and these options are dead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166986 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-25Recommit Eric's code to validate ASM string's constraints and modifiers.Bill Wendling
This code checks the ASM string to see if the output size is able to fit within the variable specified as the output. For instance, scalar-to-vector conversions may not really work. It's on by default, but can be turned off with a flag if you think you know what you're doing. This is placed under a flag ('-Wasm-operand-widths') and flag group ('-Wasm'). <rdar://problem/12284092> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166737 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-24Teach the PCH validator to check the preprocessor options, especiallyDouglas Gregor
the macros that are #define'd or #undef'd on the command line. This checking happens much earlier than the current macro-definition checking and is far cleaner, because it does a direct comparison rather than a diff of the predefines buffers. Moreover, it allows us to use the result of this check to skip over PCH files within a directory that have non-matching -D's or -U's on the command line. Finally, it improves the diagnostics a bit for mismatches, fixing <rdar://problem/8612222>. The old predefines-buffer diff'ing will go away in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166641 91177308-0d34-0410-b5e6-96231b3b80d8

since it also has an implicit exception specification. Downgrade the error to an extwarn, since at least for operator delete, system headers like to declare it as 'noexcept' whereas the implicit definition does not have an explicit exception specification. Move the exception specification for user-declared 'operator delete' functions from the type-as-written into the type, to reflect reality and to allow us to detect whether there was an implicit exception spec or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166372 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-20Accept -Wno-arc-abi without warning for a while.Nico Weber
Xcode 4.5 passes -Wno-arc-abi to clang, which makes a clang newer than r163917 warn that it doesn't understand -Wno-arc-abi. I asked if adding this is ok at http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20121015/066433.html and nobody objected. Adding this makes life a bit easier for the chromium project.

2012-10-19Allow objc_requires_super to be used to check class methods as well.Jordan Rose
Also, unify ObjCShouldCallSuperDealloc and ObjCShouldCallSuperFinalize. The two have identical behavior and will never be active at the same time. There's one last simplification now, which is that if we see a call to [super foo] and we are currently in a method named 'foo', we will /unconditionally/ clear the ObjCShouldCallSuper flag, rather than check first to see if we're in a method where calling super is required. There's no reason to pay the extra lookup price here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166285 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-19Change VerifyDiagnosticConsumer so that it *must* contain at least one ↵Andy Gibbs
"expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive. This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.

2012-10-16Add pnaclcall convention to Native Client targets.Derek Schuff
Because PNaCl bitcode must be target-independent, it uses some different bitcode representations from other targets (e.g. byval and sret for structures). This means that without additional type information, it cannot meet some native ABI requirements for some targets (e.g. passing structures containing unions by value on x86-64). To allow generation of code which uses the correct native ABIs, we also support triples such as x86_64-nacl, which uses target-dependent IR (as opposed to le32-nacl, which uses byval and sret). To allow interoperation between the two types of code, this patch adds a calling convention attribute to be used in code compiled with the target-dependent triple, which will generate code using the le32-style bitcode. This calling convention does not need to be explicitly supported in the backend because it determines bitcode representation rather than native conventions (the backend just needs to undersand how to handle byval and sret for the Native Client OS). This patch implements __attribute__((pnaclcall)) to generate calls in bitcode according to the le32 bitcode conventions, an attribute which is accepted by any Native Client target, but issues a warning otherwise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166065 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-16Implement GCC's -Wint-to-pointer-cast.David Blaikie
This implementation doesn't warn on anything that GCC doesn't warn on with the exception of templates specializations (GCC doesn't warn, Clang does). The specific skipped cases (boolean, constant expressions, enums) are open for debate/adjustment if anyone wants to demonstrate that GCC is being overly conservative here. The only really obvious false positive I found was in the Clang regression suite's MPI test - apparently MPI uses specific flag values in pointer constants.

2012-10-09The clang driver has a fairly fancy support for executing gcc instead ofRafael Espindola
clang itself. This dates back to clang's early days and while it looks like some of it is still used (for kext for example), other parts are probably dead. Remove the -ccc-clang-archs option and associated code. I don't think there is any remaining setup where clang doesn't support an architecture but it can expect an working gcc cross compiler to be available. A nice side effect is that tests no longer need to differentiate architectures that are included in production builds of clang and those that are not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165545 91177308-0d34-0410-b5e6-96231b3b80d8
