Ted Woodward fab31220fe Fix for missing prompt on Windows
Summary: On Windows (and possibly other hosts with LLDB_DISABLE_LIBEDIT defined), the (lldb) prompt won't print after async output, like from a breakpoint hit or a step. This patch forces the prompt to be printed out after async output.

Zachary Turner 190fadcdb2 Unicode support on Win32.
Win32 API calls that are Unicode aware require wide character
strings, but LLDB uses UTF8 everywhere.  This patch does conversions
wherever necessary when passing strings into and out of Win32 API
calls.

That way you can set offset breakpoints that will move as the function they are

I don't align the new address to instruction boundaries yet, so you have to get
this right yourself for now.

Adrian Prantl 6aeba89e89 Support floating point values in 128-bit SSE vector registers
The System-V x86_64 ABI requires floating point values to be passed
in 128-but SSE vector registers (xmm0, ...). When printing such a
variable this currently yields an <invalid load address>.

This patch makes LLDB's DWARF expression evaluator accept 128-bit
registers as scalars. It also relaxes the check that the size of the
result of the DWARF expression be equal to the size of the variable to a
greater-than. DWARF defers to the ABI how smaller values are being placed
in a larger register.

Implementation note: I found the code in Value::SetContext() that changes
the m_value_type after the fact to be questionable. I added a sanity check
that the Value's memory buffer has indeed been written to (this is
necessary, because we may have a scalar value in a vector register), but
really I feel like this is the wrong place to be setting it.

Zachary Turner 47c03462f5 Some fixes for case insensitive paths on Windows.
Paths on Windows are not case-sensitive.  Because of this, if a file
is called main.cpp, you should be able to set a breakpoint on it
by using the name Main.cpp.  In an ideal world, you could just
tell people to match the case, but in practice this can be a real
problem as it requires you to know whether the person who compiled
the program ran "clang++ main.cpp" or "clang++ Main.cpp", both of
which would work, regardless of what the file was actually called.

This fixes http://llvm.org/pr22667

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.

Greg Clayton ae088e52f3 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:
llvm::DenseSet<lldb_private::SymbolFile *> &searched_symbol_files
    
Each time a SymbolFile::FindTypes() is called, it needs to check the searched_symbol_files list to make sure it hasn't already been asked to find the type and return immediately if it has been checked. This will stop circular dependencies from also crashing LLDB during type queries. 

This has proven to be an issue when debugging large applications on MacOSX that use DWARF in .o files.

Pavel Labath 061140c680 Remove Timer::Initialize routine
Summary:
I've run into an issue when running unit tests, where the underlying problem turned out to be
that we were creating Timer objects (through several layers of indirection) without calling
Timer::Initialize. Since Timer's thread-local storage was not properly initialized, we were
overwriting gtest's own thread-local storage, causing test failures.

Instead of requiring that every test calls Timer::Initialize(), I remove the function altogether:
The thread-local storage can be initialized on-demand, and the g_file variable initialized to
stdout and never changed, so I have simply removed it.

Adrian McCarthy c35b91cee2 Set symbol types for function symbols loaded from PE/COFF
This fixes the regression of several tests on Windows after rL258621.

The root problem is that ObjectFilePECOFF was not setting type information for the symbols, and the new CL rejects symbols without type information, breaking functionality like thread step-over.

The fix sets the type information for functions (and creates a TODO for other types).

Along the way, I fixed some typos and formatting that made the code I was debugging harder to understand.

In the long run, we should consider replacing most of ObjectFilePECOFF with the COFF parsing code from LLVM.

This patch reworks the breakpoint filter-by-language patch to use the

symbol's name. This has the advantage that symbols compiled with debug
info will have their actual language known. Symbols without debug info
will still do the same "guess"ing because Symbol::GetLanguage() is
implemented using Mangled::GuessLanguage(). The recognition of ObjC
names was merged into Mangled::GuessLanguage.
