2009-11-09Add support for cdecl attribute. (As far as I know, it doesn't affect CodeGenEli Friedman
unless we start implementing command-line switches which override the default calling convention, so the effect is mostly to silence unknown attribute warnings.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86571 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-04Change our basic strategy for avoiding deprecation warnings when the decl useJohn McCall
appears in a deprecated context. In the new strategy, we emit the warnings as usual unless we're currently parsing a declaration, where "declaration" is restricted to mean a decl group or a few special cases in Objective C. If we *are* parsing a declaration, we queue up the deprecation warnings until the declaration has been completely parsed, and then emit them only if the decl is not deprecated. We also standardize the bookkeeping for deprecation so as to avoid special cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85998 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-18Simplify HandleFormatAttr.Daniel Dunbar
- I have this crazy dream that one day someone will invent a miraculous tool so that developers, instead of hand optimizing their source code to obscure its intent and decrease its maleability, will instead write what they mean, and this strange and wonderful tool -- which I imagine would be called something fancy sounding like "an optimizing compiler" -- will make their code fast *for* them. With all the saved time, developers could maybe even focus on making the magic "optimizing compiler" better!! - No intended functionality change, all though I expect the universe to mock me for snarkiness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84390 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Enhance diagnostics concerning attribute 'ns_returns_retained' and ↵Ted Kremenek
'cf_returns_retained' to present the range of the attribute and have the diagnostic location be the declaration that the attribute was falsely attached to. This solves the problem where these diagnostics were being suppressed when these attributes were wrapped in a macro that was defined in a system header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79496 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Introduce DeclaratorDecl and pass DeclaratorInfo through the Decl/Sema ↵Argyrios Kyrtzidis
interfaces. DeclaratorDecl contains a DeclaratorInfo* to keep type source info. Subclasses of DeclaratorDecl are FieldDecl, FunctionDecl, and VarDecl. EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo. Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79392 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-15Change handling of attribute 'malloc' to only accept the attribute on functionTed Kremenek
declarations (and not function pointers). This is consistent with GCC. Accepting this attribute on function pointers means that the attribute should be treated as a type qualifier, which apparently is not what GCC does. We obviously can change this later should we desire to enhance the 'malloc' attribute in this way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79060 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-10fix a couple of problems with section attributes:Chris Lattner
1. Passing something that isn't a string used to cause: "argument to annotate attribute was not a string literal" make it say "section attribute" instead. 2. Fix the location of the above message to point to the bad argument instead of the section token. 3. Implement rdar://4341926, by diagnosing invalid section specifiers in the frontend rather than letting them slip all the way to the assembler (a QoI win). An example of #3 is that we used to produce something like this: /var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Expected comma after segment-name /var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Rest of line ignored. 1st junk character valued 46 (.). Daniel improved clang to use llvm_report_error, so now we got: $ clang t.c -c fatal error: error in backend: Global variable 'x' has an invalid section specifier 'sadf': mach-o section specifier requires a segment and section separated by a comma. with no loc info. Now we get: $ clang t.c -fsyntax-only t.c:4:30: error: argument to 'section' attribute is not valid for this target: mach-o section specifier requires a segment and section separated by a comma int x __attribute__((section("sadf"))); ^ which is nice :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@78586 91177308-0d34-0410-b5e6-96231b3b80d8

With Doug's pending smart pointer changes for Types, it seemed natural to take this approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77510 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek
until Doug Gregor's Type smart pointer code lands (or more discussion occurs). These methods just call the new Type::getAs<XXX> methods, so we still have reduced implementation redundancy.

2009-07-16Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.Ted Kremenek
This method is intended to eventually replace the individual Type::getAsXXXType<> methods. The motivation behind this change is twofold: 1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of them are basically copy-and-paste. 2) By centralizing the implementation of the getAs<Type> logic we can more smoothly move over to Doug Gregor's proposed canonical type smart pointer scheme. Along with this patch: a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>. b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76098 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Generate error on declaration containing 'static' and '__attribute__((weak))'Fariborz Jahanian
Patch by Ryan Flynn git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75879 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Handle some more fallout with the conversion of using PointerType forTed Kremenek
Objective-C pointers to using ObjCObjectPointerType. Now the checking for 'attribute ((nonnull))' in Sema doesn't emit an error when trying to apply that attribute to a parameter that is an Objective-C pointer (this is a regression). To prevent this regression from occuring in the future, the 'nonnull.c' test was moved to test/SemaObjC and renamed 'nonnull.m'. I also enhanced the tests to show that function calls involved a NULL Objective-C pointer constant does not trigger a warning. This is consistent with GCC, but should likely be fixed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75856 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8
