Summary:
Instead of hardcoding ClangASTContext and ObjCLanguageRuntime, we can
generalize this by creating the method GetRuntimeType in
LanguageRuntime and moving the current MaybeCalculateCompleteType
implementation into ObjCLanguageruntime::GetRuntimeType

Summary:
We currently have man large arrays containing initializers for our command options.
These tables are tricky maintain as we don't have any good place to check them for consistency and
it's also hard to read (`nullptr, {}, 0` is not very descriptive).
This patch fixes this by letting table gen generate those tables. This way we can have a more readable
syntax for this (especially for all the default arguments) and we can let TableCheck check them
for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.).
Also refactoring the related data structures can now be done without changing the hundred of option initializers.
For example, this line:
```
{LLDB_OPT_SET_ALL, false, "hide-aliases", 'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."},
```
becomes this:
```
def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">;
```
For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other
option initializers tables in separate patches.

IRDynamicChecks in its current form is specific to Clang since it deals
with the C language family. It is possible that we may want to
instrument code generated for other languages, but we can factor in a
more general mechanism to do so at a later time.
This decouples ObCLanguageRuntime from Expression!

Summary:
It seems that calling Popen can return to the caller before the started process has read all the needed information
from its executable. This means that in case we delete the executable while the process is still starting up,
this test will create a zombie process which in turn leads to a failing test. On my macOS system this happens quite frequently.
This patch fixes this by letting the test synchronize with the inferior after it has started up.

Summary:
I saw while debugging that we call this file `ParseInternal`, which is not a very good name for our
fake expression file and also adds this unnecessary link between the way we name this function
and the other source location names we get from the expression parser. This patch is renaming
it to `<lldb-expr>` which is closer to the way Clang names its buffers, it doesn't depend on the
function name (which changes when I refactor this code) and it's easier to grep for.

It seems on Windows we don't handle the lldb_expr_result variable correctly:
```
AssertionError: False is not True : 'expr $__lldb_expr_result' returns expected result, got '(int &) $0 = 0x0000000000000000'
```
I'll disable the test until I can find a way to debug this on Windows.

Apparently, when using swig 1.3.40, properties to set values do not work
without the `__swig_setmethods__` workaround. I conditionally added this
back for SBTypeCategory, as it's causing a test failure on GreenDragon,

use for it and wants to resurrect, I would recommend to revise
the error messages.
llvm-svn: 365677
Summary:
While investigating breakages caused by D63110, I noticed we were
building the short options strings in three places. Some of them used a
leading ':' to detect missing arguments, and some didn't. This was the
indirect cause of D63110. Here, I move the common code into a utility
function.
Also, unify the code which appends the sentinel value at the end of the
option vector, and make it harder for users to pass invalid argc-argv
combos to getopt (another component of D63110) by having the
OptionParser::Parse function take a (Mutable)ArrayRef.
This unification has uncovered that we don't handle missing arguments
while building aliases, However, it's not possible to write an effective
test for this, as right now it is not possible to return an error out of
the alias parsing code (which means we are printing the generic
"failure" message even after this patch).

With this style, a compressed section is indicated by a "z" in the section
name, instead of a section header flag. This patch consists of two small tweaks:
- use an llvm Decompressor method in order to properly detect compressed sections
- make sure we recognise .zdebug_info (and friends) when classifying section types.
llvm-svn: 365654
Summary:
There's a number of requirements for installing LLDB on macOS that are untypical for LLVM projects: use special install-prefix for LLDB.framework, ship headers and tools as framework resources, patch RPATHs, externalize debug-info to dSYM's and strip binaries with `-ST`. For some of it we could use `llvm_externalize_debuginfo()` in the past and just add special cases. However, this complicates the code for all projects and comes with the major drawback, that it adds all these actions at build-time, i.e. dSYM creation and stripping take a lot of time and don't make sense at build-time.
LLVM's distribution mechanism (https://llvm.org/docs/BuildingADistribution.html) appears to be the natural candidate to install LLDB. Based on D64399 (enable in standalone builds), this patch integrates framework installation with the distribution mechanism and adds custom stripping flags and dSYM creation at install-time. Unlike the abandoned D61952, it leaves build-tree binaries untouched, so there's no side-effects on testing. Potential install-order issues must be handled externally.
Please let me know what you think, while I run a few more tests and add remarks+documentation.

Summary: The custom lldb-framework target was meant to encapsulate all build steps that LLDB.framework needs on top of the ordinaly liblldb. In the end all of it happens in post-build steps, so we can do the same with liblldb and cut down another source of confusion.

Patch by Wanyi Ye!
Differential Revision: https://reviews.llvm.org/D64434
llvm-svn: 365567
Summary:
Fixed `Android.rules` for running test suite on remote android
- the build configuration is not compatible with ndk structure, change it to link to static libc++
- generally clang should be able to use libc++ and will link against the right library, but some libc++ installations require the user manually link libc++abi.
- add flag `-lc++abi` to fix the test binary build failure
Added `skipIfTargetAndroid` `skipUnlessTargetAndroid` for better test support
- the `skipIfPlatform` method will ask `lldbplatformutil.getPlatform()` for platform info which is actually the os type, and //Android// is not os type but environment
- create this function to handle the android target condition
**To Run Test on Remote Android**
1 start lldb-server on your devices
2 run lldb-dotest with following configuration:
`./lldb-dotest --out-of-tree-debugserver --arch aarch64 --platform-name remote-android --platform-url connect://localhost:12345 --platform-working-dir /data/local/tmp/ --compiler your/ndk/clang`

This test was originally marked as expected failure on Windows, but it is timing out instead of outright failing now. The expectedFailure attribute does not correctly track timeouts (as in, they don't count as failures), so now this is causing the test suite to fail.
