2012-12-19PR13470: Ensure that copy-list-initialization isntantiates asRichard Smith
copy-list-initialization (and doesn't add an additional copy step): Fill in the ListInitialization bit when creating a CXXConstructExpr. Use it when instantiating initializers in order to correctly handle instantiation of copy-list-initialization. Teach TreeTransform that function arguments are initializations, and so need this special treatment too. Finally, remove some hacks which were working around SubstInitializer's shortcomings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170489 91177308-0d34-0410-b5e6-96231b3b80d8

per review discussion in r170365 This does limit these typedefs to being sequences, but no current usage requires them to be contiguous (we could expand this to a more general iterator pair range concept at some point). Also, it'd be nice if SmallVector were constructible directly from an ArrayRef but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the inverse conversion.

2012-12-18Better support for constructor initializers.Daniel Jasper
We used to format initializers like this (with a sort of hacky implementation): Constructor() : Val1(A), Val2(B) { and now format like this (with a somewhat better solution): Constructor() : Val1(A), Val2(B) { assuming this would not fit on a single line. Also added tests. As a side effect we now first analyze whether an UnwrappedLine needs to be split at all. If not, not splitting it is the best solution by definition. As this should be a very common case in normal code, not exploring the entire solution space can provide significant speedup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170457 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18CodeGen: Expand creal and cimag into complex field loadsMeador Inge
PR 14529 was opened because neither Clang or LLVM was expanding calls to creal* or cimag* into instructions that just load the respective complex field. After some discussion, it was not considered realistic to do this in LLVM because of the platform specific way complex types are expanded. Thus a way to solve this in Clang was pursued. GCC does a similar expansion. This patch adds the feature to Clang by making the creal* and cimag* functions library builtins and modifying the builtin code generator to look for the new builtin types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170455 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-17Fix PR14625 by teaching the driver to detect PWD for assembly files.Chandler Carruth
This also requires adding support to -cc1as for passing the detecting PWD down through LLVM's debug info (which in turn required the LLVM change in r170371). The test case is weak (we only test the driver behavior) because there is currently to infrastructure for running cc1as in the test suite. So those four lines are untested (much like all other lines in that file), but we have a test for the same pattern using llvm-mc in the LLVM repository. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170373 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-17[analyzer] Implement "do not inline large functions many times"Anna Zaks
performance heuristic After inlining a function with more than 13 basic blocks 32 times, we are not going to inline it anymore. The idea is that inlining large functions leads to drastic performance implications. Since the function has already been inlined, we know that we've analyzed it in many contexts. The following metrics are used: - Large function is a function with more than 13 basic blocks (we should switch to another metric, like cyclomatic complexity) - We consider that we've inlined a function many times if it's been inlined 32 times. This number is configurable with -analyzer-config max-times-inline-large=xx This heuristic addresses a performance regression introduced with inlining on one benchmark. The analyzer on this benchmark became 60 times slower with inlining turned on. The heuristic allows us to analyze it in 24% of the time. The performance improvements on the other benchmarks I've tested with are much lower - under 10%, which is expected. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170361 91177308-0d34-0410-b5e6-96231b3b80d8
