Summary:
This patch does two things. First it updates all the ABI plugins with accurate dependencies, and second it adds a tracking mechanism for add_lldb_library to denote plugin libraries, allowing us to build up a list of all the configured plugins.
This list of generated plugins will be used during generating liblldb so that we can link all the plugins into the library.
If this patch looks good I will update all the other plugins in subsequent patches.

Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.
In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.
For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

header line, backtrace output) was to remove the current pc value
from frames where we have source level information. We've been
discussing this for the past week and based on input from a group
of low level users, I believe this is the wrong default behavior
for the command line lldb tool.
lldb's backtrace will include the pc value for all stack frames
regardless of whether they have source level debug information or
not.
A related part of r286288 removes the byte offset printing for
functions with source level information (e.g. "main + 22 sourcefile.c:10"
is printed as "main sourcefile.c:10"). I don't see a compelling
case for changing this part of 286288 so I'm leaving that as-is
(in addition to the rest of 286288 which is clearly better than
the previous output style).

Summary: LLDB was using packet size advertised by the target as the max memory size to write in one go. It is wrong because packets have other overhead apart from memory payload. Also memory transferred through 'm' and 'M' packets needs 2 bytes in packet to transfer 1 of memory.

On android API level 9 the header does not get included transitively.

As far as I can see, all non-windows platforms should have this header.

Summary:
getcwd() is not available (well.. um.. deprecated?) on windows, and the way
PosixApi.h is providing it causes strange compile errors when it's included in
the wrong order. The best way to avoid that is to just not use chdir.
This replaces all uses of getcwd in generic code. There are still a couple of
more uses, but these are in platform-specific code.
chdir() is causing a similar problem, but for that there is no llvm equivalent
for that (yet).

Summary:
The server was no longer sending the thread PCs the way the client
expected them.
I changed the server to send them back as a threadstop info field,
similar to the Apple version of the server.
I also changed the client to look for them there, before querying the
server.
I added a test to ensure the server doesn't stop sending them.

For bare-metal targets, lldb was missing a command like 'load' in gdb
which can be used to create executable image on the target. This was
discussed in
http://lists.llvm.org/pipermail/lldb-dev/2016-December/011752.html
This commits adds an option to "target module load" command to provide
that functionality. It does not set the PC to entry address which will
be done separately.

This adds the LLDB_LOG macro, which enables one to write more succinct log
statements.
if (log)
log->Printf("log something: %d", var);
becomes
LLDB_LOG(log, "log something: {0}, var);
The macro still internally does the "if(log)" dance, so the arguments are only
evaluated if logging is enabled, meaning it has the same overhead as the
previous syntax.
Additionally, the log statements will be automatically prefixed with the file
and function generating the log (if the corresponding new argument to the "log
enable" command is enabled), so one does not need to manually specify this in
the log statement.
It also uses the new llvm formatv syntax, which means we don't have to worry
about PRIx64 macros and similar, and we can log complex object (llvm::StringRef,
lldb_private::Error, ...) more easily.

The NDK cmake toolchain file defines CMAKE_SYSTEM_NAME=Android, so switch the
build to use that. I have also updated the in-tree toolchain file to do that
(instead of defining __ANDROID_NDK__), so it can still be used to build.
After migrating the last bits of non-toolchainy bits out of the in-tree
toolchain, I intend to delete it.

The unit test I added in the previous commit discovered a bug in
PrependPathComponent on windows -- it was calling SetFile with the host native
path syntax, whereas it should be explicitly specifying the path syntax (as
AppendPathComponent does). This fixes it.
llvm-svn: 292106
Summary:
PrependPathComponent was unconditionally inserting path separators between the
path components. This is not correct if the prepended path is "/", which caused
problems down the line. Fix the function to use the same algorithm as
AppendPathComponent and add a test. This fixes one part of llvm.org/pr31611.

Summary:
I came across this while trying to understand what Log::Debug does. It turns out
it does not do anything, as there is no instance of someone setting a debug flag
on a stream. The same is true for the Verbose and AddPrefix flags. Removing
these will enable some cleanups in the Logging class, and it brings us closer
towards the long term goal of standardizing on llvm stream classes.
I have removed these flags and all code the code which tested for their
presence -- there wasn't much of it, mostly in SymbolFileDWARF, which is
probably going away at some point anyway.
The eBinary flag still has some users, so I am letting it life for the time
being.
