2010-05-06Diagnose deprecated/unavailable functions selected by overload resolution.John McCall

2010-05-06Rework our handling of temporary objects within the conditions ofDouglas Gregor
if/switch/while/do/for statements. Previously, we would end up either: (1) Forgetting to destroy temporaries created in the condition (!), (2) Destroying the temporaries created in the condition *before* converting the condition to a boolean value (or, in the case of a switch statement, to an integral or enumeral value), or (3) In a for statement, destroying the condition's temporaries at the end of the increment expression (!). We now destroy temporaries in conditions at the right times. This required some tweaking of the Parse/Sema interaction, since the parser was building full expressions too early in many places. Fixes PR7067. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103187 91177308-0d34-0410-b5e6-96231b3b80d8

matching gcc compiler. Fixes #include_next <...> shenanigans that lead to file-not-found failures with <cstddef> on libstdc++ 4.3.[012]. Updated C++ include header search paths for various Debian/Ubuntu and Fedora linux distros. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103177 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-06Push TypeSourceInfo::getTypeLoc() into a header file so that it'sJohn McCall
inlineable. That header file has to be TypeLoc.h, which means that TypeLoc.h needs to depend on Decl.h because TypeSourceInfo doesn't have its own header. That could be remedied, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103176 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-06Rearchitect -Wconversion and -Wsign-compare. Instead of computing themJohn McCall
"bottom-up" when implicit casts and comparisons are inserted, compute them "top-down" when the full expression is finished. Makes it easier to coordinate warnings and thus implement -Wconversion for signedness conversions without double-warning with -Wsign-compare. Also makes it possible to realize that a signedness conversion is okay because the context is performing the inverse conversion. Also simplifies some logic that was trying to calculate the ultimate comparison/result type and getting it wrong. Also fixes a problem with the C++ explicit casts which are often "implemented" in the AST with a series of implicit cast expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103174 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-05Add IgnoreParenImpCasts() to Expr, which is basically like IgnoreParenCastsJohn McCall

2010-05-05 Support for 'template' as a disambiguator (PR7030)Douglas Gregor
ParseOptionalCXXScopeSpecifier() only annotates the subset of template-ids which are not subject to lexical ambiguity. Add support for the more general case in ParseUnqualifiedId() to handle cases such as A::template B(). Also improve some diagnostic locations. Fixes PR7030, from Alp Toker! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103081 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05add a new --print-diagnostic-categories option, which causes the driver toChris Lattner
print out all of the category numbers with their description. This is useful for clients that want to map the numbers produced by --fdiagnostics-show-category=id to their human readable string form. The output is simple but utilitarian: $ clang --print-diagnostic-categories 1,Format String 2,Something Else This implements rdar://7928193 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103080 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05Reimplement code generation for copying fields in theDouglas Gregor
implicitly-generated copy constructor. Previously, Sema would perform some checking and instantiation to determine which copy constructors, etc., would be called, then CodeGen would attempt to figure out which copy constructor to call... but would get it wrong, or poke at an uninstantiated default argument, or fail in other ways. The new scheme is similar to what we now do for the implicit copy-assignment operator, where Sema performs all of the semantic analysis and builds specific ASTs that look similar to the ASTs we'd get from explicitly writing the copy constructor, so that CodeGen need only do a direct translation. However, it's not quite that simple because one cannot explicit write elementwise copy-construction of an array. So, I've extended CXXBaseOrMemberInitializer to contain a list of indexing variables used to copy-construct the elements. For example, if we have: struct A { A(const A&); }; struct B { A array[2][3]; }; then we generate an implicit copy assignment operator for B that looks something like this: B::B(const B &other) : array[i0][i1](other.array[i0][i1]) { } CodeGen will loop over the invented variables i0 and i1 to visit all elements in the array, so that each element in the destination array will be copy-constructed from the corresponding element in the source array. Of course, if we're dealing with arrays of scalars or class types with trivial copy-assignment operators, we just generate a memcpy rather than a loop. Fixes PR6928, PR5989, and PR6887. Boost.Regex now compiles and passes all of its regression tests. Conspicuously missing from this patch is handling for the exceptional case, where we need to destruct those objects that we have constructed. I'll address that case separately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103079 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-04Introduce a limit on the depth of the macro instantiation backtraceDouglas Gregor
printed in a diagnostic, similar to the limit we already have on the depth of the template instantiation backtrace. The macro instantiation backtrace is limited to 10 "instantiated from:" diagnostics; when it's longer than that, we'll show the first half, then say how many were suppressed, then show the second half. The limit can be changed with -fmacro-instantiation-limit=N, and turned off with N=0.
