The Python import works by ensuring the directory of the module or package is in sys.path, and then it does a Python `import foo`. The original code was not escaping the backslashes in the directory path, so this wasn't working.

os to "ios" or "macosx" if it is unspecified. For environments
where there genuinely is no os, we don't want to errantly
convert that to ios/macosx, e.g. bare board debugging.
Change PlatformRemoteiOS, PlatformRemoteAppleWatch, and
PlatformRemoteAppleTV to not create themselves if we have
an unspecified OS. Same problem - these are not appropriate
platforms for bare board debugging environments.
Have Process::Attach's logging take place if either
process or target logging is enabled.

Summary:
SetThreadStopInfo was checking for a breakpoint at the current PC several times. This merges the
identical code into a separate function. I've left one breakpoint check alone, as it was doing
more complicated stuff, and it did not see a way to merge that without making the interface
complicated. NFC.

Summary:
This resolves a similar problem as D16720 (which handled the case when we single-step onto a
breakpoint), but this one deals with involutary stops: when we stop a thread (e.g. because
another thread has hit a breakpont and we are doing a full stop), we can end up stopping it right
before it executes a breakpoint instruction. In this case, the stop reason will be empty, but we
will still step over the breakpoint when do the next resume, thereby missing a breakpoint hit.
I have observed this happening in TestConcurrentEvents, but I have no idea how to reproduce this
behavior more reliably.

This test sets the compiler optimization level to -O1 and
makes some assumptions about how local frame vars will be
stored (i.e. in registers). These assumptions are not always
true.
I did a first-pass set of improvements that:
(1) no longer assumes that every one of the target locations has
every variable in a register. Sometimes the compiler
is even smarter and skips the register entirely.
(2) simply expects one of the 5 or so variables it checks
to be in a register.
This test probably passes on a whole lot more systems than it
used to now. This is certainly true on OS X.

Summary:
The '-p' option for dotest.py was ignored in multiprocess mode,

Summary:
The logic to read modules from memory was added to LoadModuleAtAddress
in the dynamic loader, but not in process gdb remote. This means that when
the remote uses svr4 packets to give library info, libraries only present
on the remote will not be loaded.
This patch therefore involves some code duplication from LoadModuleAtAddress
in the dynamic loader, but removing this would require some amount of code
refactoring.

Previously we had 3 different method to run shell commands on the
target and 4 copy of code waiting until a given file appears on the
target device (used for syncronization). This CL merges these methods
to 1 run_platform_command and 1 wait_for_file_on_target functions
located in some utility classes.

Summary:
There was a bug in linux core file handling, where if there was a running process with the same
process id as the id in the core file, the core file debugging would fail, as we would pull some
pieces of information (ProcessInfo structure) from the running process instead of the core file.
I fix this by routing the ProcessInfo requests through the Process class and overriding it in
ProcessElfCore to return correct data.
A (slightly convoluted) test is included.

in thumb mode into one method in ArchSpec, replace checks for
specific cores in the disassembler with calls to this. Also call
this from the arm instruction emulation code.
The determination of whether a given ArchSpec is thumb-only is still
a bit of a hack, but at least the hack is consolidated into a single
place. In my original version of this patch http://reviews.llvm.org/D13578
I was calling into llvm's feature arm feature tables to make this
determination, like
#include "llvm/Support/TargetRegistry.h"
#include "llvm/MC/MCSubtargetInfo.h"
#include "llvm/../../lib/Target/ARM/ARMGenRegisterInfo.inc"
#include "llvm/../../lib/Target/ARM/ARMFeatures.h"
[...]
std::string triple (GetTriple().getTriple());
const char *cpu = "";
const char *features_str = "";
const llvm::Target *curr_target = llvm::TargetRegistry::lookupTarget(triple.c_str(), Error);
std::unique_ptr<llvm::MCSubtargetInfo> subtarget_info_up (curr_target->createMCSubtargetInfo(triple.c_str(), cpu, features_str));
if (subtarget_info_up->getFeatureBits()[llvm::ARM::FeatureNoARM])
{
return true;
}
but those tables are post-llvm-build generated and linking against them
for all of our different build system methods was a big hiccup that I
haven't had time to revisit convincingly.
I'll keep that reviews.llvm.org patch around to remind myself that I
need to take another run at linking against the necessary tables
again in llvm.

Teach LLDB that different shells have different characters they are sensitive to, and use that knowledge to do shell-aware escaping
This helps solve a class of problems on OS X where LLDB would try to launch via sh, and run into problems if the command line being passed to the inferior contained such special markers (hint: the shell would error out and we'd fail to launch)
This makes those launch scenarios work transparently via shell expansion
Slightly improve the error message when this kind of failure occurs to at least suggest that the user try going through 'process launch' directly

Summary:
Even though FileSpec attempted to handle both kinds of path syntaxes (posix and windows) on both
platforms, it relied on the llvm path library to do its work, whose behavior differed on
different platforms. This led to subtle differences in FileSpec behavior between platforms. This
replaces the pieces of the llvm library with our own implementations. The functions are simply
copied from llvm, with #ifdefs replaced by runtime checks for ePathSyntaxWindows.

In doing so, two bugs were uncovered (and fixed). The first bug
is that ClangASTContext::RemoveFastQualifiers() was broken, and
was not removing fast qualifiers (or doing anything else for that
matter). The second bug is that UnifyAccessSpecifiers treated
AS_None asymmetrically, which is probably an edge case, but seems
like a bug nonetheless.

TypeSP SymbolFileDWARF::FindDefinitionTypeForDWARFDeclContext (const DWARFDeclContext &dwarf_decl_ctx);
The problem was we might be looking for a type "Foo", and find one from another langauge. Then the DWARFASTParserClang would try to make an AST type using a CompilerType that might return an empty.
This fix makes sure that when we create a DWARFDeclContext from a DWARFDIE that the DWARFDeclContext we set the language of the DIE. Then when we go to find matches for DWARFDeclContext, we end up with bunch of DIEs. We check each DWARFDIE that we found by asking it for its language and making sure the language is compatible with the type system that we want to use. This keeps us from using the wrong types to resolve forward declarations.
