2012-06-29Update the %diff modifer to have an alternate string print when a template treeRichard Trieu
is selected. This will allow more flexibility when converting diagnostics to use template type diffing.

2012-06-27From Vassil Vassilev:Axel Naumann
add interface for removing a FileEntry from the cache. Forces a re-read the contents from disk, e.g. because a tool (like cling) wants to pick up a modified file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159256 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-26Add template type diffing to Clang. This feature will provide a betterRichard Trieu
comparison between two templated types when they both appear in a diagnostic. Type elision will remove indentical template arguments, which can be disabled with -fno-elide-type. Cyan highlighting is applied to the differing types. For more formatting, -fdiagnostic-show-template-tree will output the template type as an indented text tree, with differences appearing inline. Template tree works with or without type elision. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159216 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-21Remove a goofy CMake hack and use the standard CMake facilities toChandler Carruth
express library-level dependencies within Clang. This is no more verbose really, and plays nicer with the rest of the CMake facilities. It should also have no change in functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158888 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Introduce ObjCRuntime::hasWeakClassImport() and use it in the appropriateJohn McCall
places. I've turned this off for the GNU runtimes --- I don't know if they support weak class import, but it's easy enough for them to opt in. Also tweak a comment per review by Jordan. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158860 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
2012-06-19Revert 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

2012-06-11Add PPC support for translating gcc-style -mcpu options into LLVM ↵Hal Finkel
-target-cpu options. This functionality is based on what is done on ARM, and enables selecting PPC CPUs in a way compatible with gcc's driver. Also, mirroring gcc (and what is done on x86), -mcpu=native support was added. This uses the host cpu detection from LLVM (which will also soon be updated by refactoring code currently in backend). In order for this to work, the target needs a list of valid CPUs -- we now accept all CPUs accepted by LLVM. A few preprocessor defines for common CPU types have been added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158334 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-06Add pedantic warning -Wempty-translation-unit (C11 6.9p1).Jordan Rose
In standard C since C89, a 'translation-unit' is syntactically defined to have at least one "external-declaration", which is either a decl or a function definition. In Clang the latter gives us a declaration as well. The tricky bit about this warning is that our predefines can contain external declarations (__builtin_va_list and the 128-bit integer types). Therefore our AST parser now makes sure we have at least one declaration that doesn't come from the predefines buffer. Also, remove bogus warning about empty source files. This doesn't catch source files that only contain comments, and never fired anyway because of our predefines.

2012-04-06SourceManager: Vectorize ComputeLineNumbers for SSE2.Benjamin Kramer
This method is very hot, it is called when emitting diagnostics, in -E mode and for many #pragma handlers. It scans through the whole source file to count newlines, records and caches them in a vector. The speedup from vectorization isn't very large, as we fall back to bytewise scanning when we hit a newline. There might be a way to avoid leaving the sse loop but everything I tried didn't work out because a call to push_back clobbers xmm registers. About 2% speedup on average on "clang -E > /dev/null" of all .cpp files in clang's lib/Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154204 91177308-0d34-0410-b5e6-96231b3b80d8
