2013-01-15Do not traverse the break-state when we know we cannot break anyway.Manuel Klimek
This is an optimization that djasper spottet. For now, we do not format anything after the first token that belongs to such an implicit string literal. All our state is not made for handling that anyway, so we'll revisit this if we find a problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172537 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Fix formatting of preprocessor directives (incluces, warnings & errors).Manuel Klimek
Treat tokens inside <> for includes and everything from the second token of a warning / error on as an implicit string literal, e.g. do not change its whitespace at all. Now correctly formats: #include < path with space > #error Leave all white!!!!! space* alone! Note that for #error and #warning we still format the space up to the first token of the text, so: # error Text will become #error Text git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172536 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Improve operator kind detection in presence of comments.Daniel Jasper
We used to incorrectly identify some operators (*, &, +, -, etc.) if there were comments around them. Example: Before: int a = /**/ - 1; After: int a = /**/ -1; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172533 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-15Fixes various bugs around the keywords class, struct and union.Manuel Klimek
This switches to parsing record definitions only if we can clearly identify them. We're specifically allowing common patterns for visibility control through macros and attributes, but we cannot currently fix all instances. This fixes all known bugs we have though. Before: static class A f() { return g(); } int x; After: static class A f() { return g(); } int x; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172530 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-15PR14918: Don't confuse braced-init-lists after template variable declarationsRichard Smith
with function definitions. We really should remove Parser::isDeclarationAfterDeclarator entirely, since it's meaningless in C++11 (an open brace could be either a function definition or an initializer, which is what it's trying to differentiate between). The other caller of it happens to be correct right now... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172510 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-15Fix behavior of [[gnu::]] function attributes. Per g++'s behavior, theseRichard Smith
attributes appertain to a declaration, even though they would be much more naturally modelled as appertaining to a function type. Previously, we would try to distribute them from the declarator to the function type, then reject them for being at an incorrect location. Now, we just distribute them as far as the declarator; the existing attribute handling code can actually apply them there just fine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172504 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-14[analyzer] -drain is not an alias for -release.Jordan Rose
This was previously added to support -[NSAutoreleasePool drain], which behaves like -release under non-GC and "please collect" under GC. We're not currently modeling the autorelease pool stack, though, so we can just take this out entirely. Fixes PR14927. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172444 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Switch autolinking metadata format over to actual linker options, e.g.,Douglas Gregor
!0 = metadata !{metadata !"-lautolink"} !1 = metadata !{metadata !"-framework", metadata !"autolink_framework"} referenced from llvm.module.linkoptions, e.g., !llvm.module.linkoptions = !{!0, !1, !2, !3} This conceptually moves the logic for figuring out the syntax the linker will accept from LLVM into Clang. Moreover, it makes it easier to support MSVC's #pragma comment(linker, "some option") in the future, should anyone care to do so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172441 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Infer "link" lines for top-level frameworks. Essentially, a frameworkDouglas Gregor
will have a shared library with the same name as its framework (and no suffix!) within its .framework directory. Detect this both when inferring the whole top-level framework and when parsing a module map. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172439 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14This patch addresses varargs processing for small complex types underBill Schmidt
the 64-bit PowerPC ELF ABI. The ABI requires that the real and imaginary parts of a complex argument each occupy their own doubleword. Arguments smaller than 8 bytes are right-adjusted within the doubleword. Clang expects EmitVAARG() to return a pointer to a structure in which the real and imaginary parts are packed adjacently in memory. To accomplish this, we generate code to load the code appropriately from the varargs location and pack the values into a temporary variable in the form Clang expects, returning a pointer to that structure. The test case demonstrates correct code generation for all "small" complex types on PPC64: int, short, char, and float. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172438 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Implement parsing, AST, (de-)serialization, and placeholder globalDouglas Gregor
metadata for linking against the libraries/frameworks for imported modules. The module map language is extended with a new "link" directive that specifies what library or framework to link against when a module is imported, e.g., link "clangAST" or link framework "MyFramework" Importing the corresponding module (or any of its submodules) will eventually link against the named library/framework. For now, I've added some placeholder global metadata that encodes the imported libraries/frameworks, so that we can test that this information gets through to the IR. The format of the data is still under discussion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172437 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Fixes formatting of nested brace initializers.Manuel Klimek
