Enable -gcolumn-info by default. This patch flips the default value for -gcolumn-info to be on by default. I discussed the rationale and provided compile/size data in: http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-June/074290.html This also updates the documentation and some tests that relied on the lack of column information. Some tests had column information in the expected output, but it was wrong (the tsan tests). Others were using the driver to execute. llvm-svn: 212781

Revert "Revert "Debug Info: Using declarations/DW_TAG_imported_declaration of variables, types, and functions."" This reverts commit r181947 (git d2990ce56a16050cac0d7937ec9919ff54c6df62 ) This addresses one of the two issues identified in r181947, ensuring that types imported via using declarations only result in a declaration being emitted for the type, not a definition. The second issue (emitting using declarations that are unused) is hopefully an acceptable increase as the real fix for this would be a bit difficult (probably at best we could record which using directives were involved in lookups - but may not have been the result of the lookup). This also ensures that DW_TAG_imported_declarations (& directives) are not emitted in line-tables-only mode as well as ensuring that typedefs only require/emit declarations (rather than definitions) for referenced types. llvm-svn: 182231

DebugInfo: handle the DI asm printing change to reword '[fwd]' as '[decl]' and add '[def]' for non-decl tag types This is to make test cases looking for definitions more legible by making the definition explicit rather than just the absence of '[fwd]'. This allowed the debug-info-record tests to be rephrased - and in the interests of reducing the number of individual test cases/invocations we have, I merged them into one file, separated them with namespaces (& then moved them to C++ because namespaces are great). If they need to remain 'C' only tests, they can be moved back. (I didn't group them with 'debug-info-class.cpp' because these tests only apply to -fno-limit-debug-info) I removed the pieces of code that would cause these tests to pass under -flimit-debug-info to ensure the tests remain relevant to their fixes should we ever improve -flimit-debug-info to catch that kind of code. This commit is version locked with the corresponding change to DebugInfo.h in LLVM. Except some transient buildbot fallout. llvm-svn: 184524
