Wired-up the new LLVM diagnostic system into clang diagnostic system. The approach is similar to the existing inline-asm reporting, just more general. <rdar://problem/15886278> llvm-svn: 200931

// REQUIRES: x86-registered-target
// Play around with backend reporting:
// _REGULAR_: Regular behavior, no warning switch enabled.
// _PROMOTE_: Promote warning to error.
// _IGNORE_: Drop backend warning.

Make '-Werror=frame-larger-than=' and associated diagnostic pragmas GCC-compatible It turns out the trailing '=' really is part of the option name spelling and treating it as such gets us compatible with GCC's -Werror= and pragmas. (GCC doesn't appear to support any -Wno- form for this diagnostic but we do.) llvm-svn: 210503

Implement -Wframe-larger-than backend diagnostic Add driver and frontend support for the GCC -Wframe-larger-than=bytes warning. This is the first GCC-compatible backend diagnostic built around LLVM's reporting feature. This commit adds infrastructure to perform reverse lookup from mangled names emitted after LLVM IR generation. We use that to resolve precise locations and originating AST functions, lambdas or block declarations to produce seamless codegen-guided diagnostics. An associated change, StringMap now maintains unique mangled name strings instead of allocating copies. This is a net memory saving in C++ and a small hit for C where we no longer reuse IdentifierInfo storage, pending further optimisation. llvm-svn: 210293
