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.

Two variables with the same name declared in two if conditions in the same
scope are no longer coalesced into one.

This resolves the last of the PR14606 failures in the GDB 7.5 test
suite. (but there are still unresolved issues in the imported_decl case
- we need to implement optional/lazy decls for functions & variables
like we already do for types)

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.

This reverts commit r181393 (git 3923d6a87fe7b2c91cc4a7dbd90c4ec7e2316bcd).
This seems to be emitting too much extra debug info for two (known)
reasons:
* full class definitions are emitted when only declarations are expected
* unused using declarations still produce DW_TAG_imported_declarations
llvm-svn: 181947
We might benefit from API refactoring here (why pass in a value that's
derived from another parameter?) but this is the immediate issue.
llvm-svn: 181747
Basic support is implemented here - it still doesn't account for
declared-but-not-defined variables or functions. It cannot handle out of
order (declared, 'using', then defined) cases for variables, but can
handle that for functions (& can handle declared, 'using'd, and not
defined at all cases for types).

This reverts commit 5035c483b7fcbf0fa2a7afba24fa35a10995d195.
This schema change wasn't necessary after all. I'm going ith a different
solution that will hopefully use space more conservatively.

This isn't necessary & with the next change to LLVM the DW_TAG_file_type entry
won't be emitted at all - only the raw filename/directory pair, so match on
that directly instead.
llvm-svn: 177609
The #line directive is mostly for backend testing (keeping these files matching
should simplify maintenance somewhat) though the corresponding backend test
improvement/update doesn't verify the file information directly just yet.
Coming in a later iteration.

This test seeks a verbose comment in output. By default, "-integrated-as" sets verbose-asm. Cygming is not ready for -integrated-as yet.
