2011-06-23fix autoconf build from r133710Dylan Noblesmith
Sorry! This commit worked in CMake, but CXX_INCLUDE_ROOT is defined in a different config.h for autoconf. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133715 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-23avoid using config.h in public headersDylan Noblesmith
This is the only usage in clang's headers, and it's for a define that only exists on CMake builds for the sake of the MSVC compiler, so just use an ifdef instead. Also add an include for config.h in a file that actually needs it, and was picking it up by accident indirectly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133710 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-23Fix a bunch of HTML compliance problems with LanguageExtensions.htmlSean Hunt
One weird thing is the addition of several <a name=""> tags where previously there were id attributes on the <h3> tags. This is because the id attribute must begin with a letter, not an underscore. The name attribute is not so constrained, so links will continue to work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133677 91177308-0d34-0410-b5e6-96231b3b80d8

and into a new file, SemaExprMember.cpp, bringing SemaExpr.cpp just under 10,000 lines of code (ugh). No functionality change, although I intend to do some refactoring of this code to address PR8368 at some point in the "near" future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133674 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-22lit support for REQUIRES: asserts.Andrew Trick
Take #2. Don't piggyback on the existing config.build_mode. Instead, define a new lit feature for each build feature we need (currently just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define this feature within test/lit.site.cfg. This doesn't require any lit harness changes and should be more robust across build systems. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133665 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-22Implement the C++0x move optimization for Automatic Reference CountingDouglas Gregor
objects, so that we steal the retain count of a temporary __strong pointer (zeroing out that temporary), eliding a retain/release pair. Addresses <rdar://problem/9364932>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133621 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-22When binding a reference to an Automatic Reference Counting temporary,Douglas Gregor
retain/release the temporary object appropriately. Previously, we would only perform the retain/release operations when the reference would extend the lifetime of the temporary, but this does the wrong thing across calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133620 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-22Emit @finally blocks completely lazily instead of forcing theirJohn McCall
existence by always threading an edge from the catchall. Not doing this was previously causing a crash in the very extreme case where neither the normal cleanup nor the EH catchall was actually reachable: we would delete the catchall entry block, which would cause us to delete the entry block of the finally cleanup as well because the cleanup logic would merge the blocks, which in turn triggered an assert because later blocks in the finally would still be using values from the entry. Laziness turns out to be the most elegant solution to the problem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133601 91177308-0d34-0410-b5e6-96231b3b80d8
