The rationale here is that ArchSpec is used throughout the codebase,
including in places which should not depend on the rest of the code in
the Core module.
This commit touches many files, but most of it is just renaming of
#include lines. In a couple of cases, I removed the #include ArchSpec
line altogether, as the file was not using it. In one or two places,
this necessitated adding other #includes like lldb-private-defines.h.

Summary:
At present, several gtests in the lldb open source codebase are using
#include statements rooted at $(SOURCE_ROOT)/${LLDB_PROJECT_ROOT}.
This patch cleans up this directory/include structure for both CMake and
Xcode build systems.

This allows for the stack size to be configured, which isn't
possible with std::thread. Prevents overflowing the stack when
performing complex operations in the task pool on darwin,
where the default pthread stack size is only 512kb.
This also moves TaskPool from Utility to Host.

Summary:
The EncodingError test ensures that trying to encode a multibyte wchar
with a given codepage fails. If setlocale() fails, the encoding is
performed using the current locale, which may or may not fail.
This patch asserts that both setlocale() operations are successful, as
well as falling back to a widely available unibyte encoding for
non-Windows systems.

Fetching an input file required about five lines of code, and this was

Summary:
This adds functions to convert between llvm::Error and Status classes.
Posix errors in Status are represented as llvm::ECError, and the rest as
llvm::StringError.
For the conversion from Error to Status, ECError is again represented as
a posix error in Status, while other errors are stored as generic errors
and only the string value is preserved.

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

This was causing a test failure in one of LLDB's tests which
specifically dealt with a limitation in LLVM's implementation
of home_directory() that LLDB's own implementation had worked
around.
This limitation has been addressed in r298513 on the LLVM side,
so the failing test (which is now unnecessary as the limitation
no longer exists) was removed in r298519, allowing this patch to
be re-submitted without modification.

Summary:
previously we switched to llvm streams for log output, this completes
the switch for the error streams.
I also clean up the includes and remove the unused argument from
DisableAllLogChannels().
This required adding a bit of boiler plate to convert the output in the
command interpreter, but that should go away when we switch command
results to use llvm streams as well.

Summary:
This fixes two threading issues in the logging code. The access to the
mask and options flags had data races when we were trying to
enable/disable logging while another thread was writing to the log.
Since we can log from almost any context, and we want it to be fast, so
I avoided locking primitives and used atomic variables instead. I have
also removed the (unused) setters for the mask and flags to make sure
that the only way to set them is through the enable/disable channel
functions.
I also add tests, which when run under tsan, verify that the use cases
like "doing an LLDB_LOGV while another thread disables logging" are
data-race-free.

Summary:
I originally set out to move the NameMatches closer to the relevant
function and add some unit tests. However, in the process I've found a
couple of bugs in the implementation:
- the early exits where not always correct:
- (test==pattern) does not mean the match will always suceed because
of regular expressions
- pattern.empty() does not mean the match will fail because the "" is
a valid prefix of any string
So I cleaned up those and added some tests. The only tricky part here
was that regcomp() implementation on darwin did not recognise the empty
string as a regular expression and returned an REG_EMPTY error instead.
The simples fix here seemed to be to replace the empty expression with
an equivalent non-empty one.

The way of injecting an error into the printf call was not working on
darwin - the C library still happily format the character. It only
returns an error after we use a wide character that does not fit into a
single byte, so switch the test to use that.

Summary:
Per discussion in D28616, having two ways two request logging (log
enable lldb XXX verbose && log enable -v lldb XXX) is confusing. This
removes the first option and standardizes all code to use the second
one.
I've added a LLDB_LOGV macro as a shorthand for if(log &&
log->GetVerbose()) and switched most of the affected log statements to
use that (I've only left a couple of cases that were doing complex
computations in an if(log) block).

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

The rewrite of StringExtractor::GetHexMaxU32 changes functionality in a way which makes
lldb-server crash. The crash (assert) happens when parsing the "qRegisterInfo0" packet, because
the function tries to drop_front more bytes than the packet contains. It's not clear to me
whether we should consider this a bug in the caller or the callee, but it any case, it worked
before, so I am reverting this until we can figure out what the proper interface should be.

Makes Peek() return a StringRef instead of a const char*.
This leads to a few callers of Peek() being able to be made a
little nicer (for example using StringRef member functions instead
of c-style strncmp and related functions) and generally safer
usage.

This is a NFC that adds more unit test coverage of the GetHex***
functions as well as the functions to extract numbers with a
specific endianness.

MutableArrayRef<T> is essentially a safer version of passing around

StringExtractor::GetNameColonValue() looks for a substring of the
form "<name>:<value>" and returns <name> and <value> to the caller.
This results in two unnecessary string copies, since the name and
value are not translated in any way and simply returned as-is.
By converting this to return StringRefs we can get rid of hundreds
of string copies.
llvm-svn: 280000
These are helpful on their own, but will be even more useful
once the GetNameColonValue is updated to return StringRefs
instead of std::strings.

The purpose of the class is to make it easy to execute tasks in parallel
Basic design goals:
* Have a very lightweight and easy to use interface where a list of
lambdas can be executed in parallel
* Use a global thread pool to limit the number of threads used
(std::async don't do it on Linux) and to eliminate the thread creation
overhead
* Destroy the thread currently not in use to avoid the confusion caused
by them during debugging LLDB
Possible future improvements:
* Possibility to cancel already added, but not yet started tasks
* Parallel for_each implementation
* Optimizations in the thread creation destroyation code
