Jason Molenda 62e0681afb Add -Wimplicit-fallthrough command line option to clang in 
the xcode project file to catch switch statements that have a
case that falls through unintentionally.

Define LLVM_FALLTHROUGH to indicate instances where a case has code
and intends to fall through.  This should be in llvm/Support/Compiler.h;
Peter Collingbourne originally checked in there (r237766), then
reverted (r237941) because he didn't have time to mark up all the
'case' statements that were intended to fall through.  I put together
a patch to get this back in llvm http://reviews.llvm.org/D17063 but
it hasn't been approved in the past week.  I added a new
lldb-private-defines.h to hold the definition for now.

Every place in lldb where there is a comment that the fall-through
is intentional, I added LLVM_FALLTHROUGH to silence the warning.
I haven't tried to identify whether the fallthrough is a bug or
not in the other places.

I haven't tried to add this to the cmake option build flags.
This warning will only work for clang.

This build cleanly (with some new warnings) on macosx with clang
under xcodebuild, but if this causes problems for people on other
configurations, I'll back it out.

ObjCLanguageRuntime.cpp Now that SymbolFileDWARF supports having types in completely separate .pcm file with "-fmodules -gmodules", each SymbolFileDWARF can reference module DWARF info by looking in other DWARF files. Then if you have 1000 .o files that each reference one or more .pcm files in their debug info, a simple Module::FindTypes(...) call can end up searching the same .pcm file over and over and over. Now all internal FindTypes methods in classes (ModuleList, Module, SymbolFile) now take an extra argument: 2016-02-10 21:28:13 +00:00
