Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

[DEBUGINFO] Add support for emission of the debug directives only. Summary: Added option -gline-directives-only to support emission of the debug directives only. It behaves very similar to -gline-tables-only, except that it sets llvm debug info emission kind to llvm::DICompileUnit::DebugDirectivesOnly.

Initialize debug info for special cases of functions that lack declarations and are generated by Clang (global initializers/destructors, thunks) . Fixes PR13942. llvm-svn: 166676

Distinguish `__block` variables that are captured by escaping blocks from those that aren't. This patch changes the way __block variables that aren't captured by escaping blocks are handled: - Since non-escaping blocks on the stack never get copied to the heap (see https://reviews.llvm.org/D49303), Sema shouldn't error out when the type of a non-escaping __block variable doesn't have an accessible copy constructor. - IRGen doesn't have to use the specialized byref structure (see https://clang.llvm.org/docs/Block-ABI-Apple.html#id8) for a non-escaping __block variable anymore. Instead IRGen can emit the variable as a normal variable and copy the reference to the block literal. Byref copy/dispose helpers aren't needed either. This reapplies r343518 after fixing a use-after-free bug in function Sema::ActOnBlockStmtExpr where the BlockScopeInfo was dereferenced after it was popped and deleted. rdar://problem/39352313 Differential Revision: https://reviews.llvm.org/D51564 llvm-svn: 343542

DebugInfo: Metadata constructs now start with DI* LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week.
