2012-04-05Enhance testing a bit to make sure that we're omitting theEric Christopher
getter and setter when they're synthesized with the default names. rdar://11179756 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154130 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-04Enter an expression evaluation context when parsingJohn McCall
statement-expressions. Prevents cleanups and such from being claimed by the first full-expression in the block. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153989 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-03Change location information for synthesized properties to be at theEric Christopher
property file/line rather than the @synthesize file/line. Avoids some nasty confusing-ness with conflating the file from the scope and the line from the original declaration. Use the current scope location as a separate parameter so that we can match it up better in the line table with the beginning of the scope. Update a couple of testcases accordingly since I had to change that we actually use the passed in location in EmitFunctionStart and for the new metadata parameter and add a new testcase to make sure we've got the right line numbers for synthesized properties.

2012-03-30The UTF16 string referenced by a CFString should go into the __TEXT,__ustringBill Wendling
section. A 'normal' string will go into the __TEXT,__const section, but this isn't good for UTF16 strings. The __ustring section allows for coalescing, among other niceties (such as allowing the linker to easily split up strings). Instead of outputting the UTF16 string as a series of bytes, output it as a series of shorts. The back-end will then nicely place the UTF16 string into the correct section, because it's a mensch. <rdar://problem/10655949> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153710 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Whether an argument is required (in contrast with being anJohn McCall
optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150788 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-16Use the new method for specifying garbage collection metadata in the module.Bill Wendling
The garbage collection metadata needs to be merged "intelligently", when two or more modules are linked together, and not merely appended. (Appending creates a section which is too large.) The module flags metadata method is the way to do this. <rdar://problem/8198537> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150648 91177308-0d34-0410-b5e6-96231b3b80d8
