Pavel Labath bcadb5a3d1 ScriptInterpreterPython cleanup
Instead of #ifdef-ing the contents of all files in the plugin for all
non-python builds, just disable the plugin at the cmake level. Also,
remove spurious extra linking of the Python plugin in liblldb. This
plugin is already included as a part of LLDB_ALL_PLUGINS variable.

Pavel Labath c7c9d76187 IRInterpreter: fix sign extension of small types (pr37840)
Sign-extension of small types (e.g. short) was not handled correctly.
The reason for that was that when we were assigning the a value to the
Scalar object, we would accidentally promote the type to int (even
though the assignment code in AssignTypeToMatch tried to cast the value
to the appropriate type, it would still invoke the "int" version of
operator=). Instead, I use the APInt version of operator=, where the
bitwidth is specified explicitly. Among other things, this allows us to
fold the individual size cases into one.

Summary:
The only reason python was used in the Host module was to compute the

moving the path computation into the python plugin and modifying
SBHostOS class to call into this module for ePathTypePythonDir.

Raphael Isemann 1246890964 Refactor OnExit utility class in ClangUserExpression
Summary:
OnExit ensures we call `ResetDeclMap` before this method ends. However,
we also have a few manual calls to ResetDeclMap in there that are actually unnecessary
because of this (calling the method multiple times has no effect). This patch also moves
the class out of the method that we can reuse it for the upcoming method that handles

Pavel Labath 60f028ff03 Replace HostInfo::GetLLDBPath with specific functions
Summary:
Instead of a function taking an enum value determining which path to
return, we now have a suite of functions, each returning a single path
kind. This makes it easy to move the python-path function into a
specific plugin in a follow-up commit.

All the users of GetLLDBPath were converted to call specific functions
instead. Most of them were hard-coding the enum value anyway, so this
conversion was simple. The only exception was SBHostOS, which I've
changed to use a switch on the incoming enum value.

Jason Molenda 87f0f95e4c Some NFC changes to how we scan of kexts & kernels in memory in the
DynamicLoaderDarwinKernel plugin.  Created a new function ReadMachHeader
and instead of reading through the target cached memory reader,
start by reading only a mach header sized chunk of memory, then
check it for a valid mach-o magic # and use the size of the load
commands to pre-fetch the entire load commands of the kext which
is the only thing we're going to read, instead of letting the generic
mach-o parser read it in 512 byte chunks.

Functionally this is doing exactly the same thing as before, but by
cutting down on the # of packets going back and forth, even on a 
local connection it's close to a quarter faster than it was before.

Alex Langford 27510c18ad Introduce lldb-framework CMake target and centralize its logic
Summary:
In this patch I aim to do the following:

1) Create an lldb-framework target that acts as the target that handles generating LLDB.framework. Previously, liblldb acted as the target for generating the framework in addition to generating the actual lldb library. This made the target feel overloaded.
2) Centralize framework generation as much as it makes sense to do so.
3) Create a target lldb-suite, which depends on every tool and library that makes liblldb fully functional. One result of having this target is it makes tracking dependencies much clearer.

Jonas Devlieghere 937348cd13 [FileSpec] Make style argument mandatory for SetFile. NFC
SetFile has an optional style argument which defaulted to the native
style. This patch makes that argument mandatory so clients of the
FileSpec class are forced to think about the correct syntax.

At the same time this introduces a (protected) convenience method to
update the file from within the FileSpec class that keeps the current
style.

These two changes together prevent a potential pitfall where the style
might be forgotten, leading to the path being updated and the style
unintentionally being changed to the host style.

Stella Stamenova 9d6fabf9e3 [lit] Split test_set_working_dir TestProcessLaunch into two tests and fix it on Windows
Summary:
test_set_working_dir was testing two scenario: failure to set the working dir because of a non existent directory and succeeding to set the working directory. Since the negative case fails on both Linux and Windows, the positive case was never tested. I split the test into two which allows us to always run both the negative and positive cases. The positive case now succeeds on Linux and the negative case still fails.
During the investigation, it turned out that lldbtest.py will try to execute a process launch command up to 3 times if the command failed. This means that we could be covering up intermittent failures by running any test that does process launch multiple times without ever realizing it. I've changed the counter to 1 (though it can still be overwritten with the environment variable).
This change also fixes both the positive and negative cases on Windows. There were a few issues:
1) In ProcessLauncherWindows::LaunchProcess, the error was not retrieved until CloseHandle was possibly called. Since CloseHandle is also a system API, its success would overwrite any existing error that could be retrieved using GetLastError. So by the time the error was retrieved, it was now a success.
2) In DebuggerThread::StopDebugging TerminateProcess was called on the process handle regardless of whether it was a valid handle. This was causing the process to crash when the handle was LLDB_INVALID_PROCESS (0xFFFFFFFF).
3) In ProcessWindows::DoLaunch we need to check that the working directory exists before launching the process to have the same behavior as other platforms which first check the directory and then launch process. This way we also control the exact error string.

Raphael Isemann 2c77eefe85 Add modules support for lldb headers in include/
Summary:
This patch adds a modulemap which allows compiling the lldb headers into C++ modules
(for example in builds with LLVM_ENABLE_MODULES=On).

Even though most of the affected code has been cleaned up to work with the more strict
C++ module semantics, there are still some workarounds left in the current modulemap
(the most obvious one is the big `lldb` wrapper module).

It also moves the Obj-C++ files in lldb to their own subdirectories. This was necessary
because we need to filter out the modules flags for this code.

Note: With the latest clang and libstdc++ it seems necessary to have a STL C++ module
to get a working LLVM_ENABLE_MODULES build for lldb. Otherwise clang will falsely
detect ODR violations in the textually included STL code inside the lldb modules.

Summary:
This kind of functionality is useful to other project apart from clang.
LLDB works with version numbers a lot, but it does not have a convenient
abstraction for this. Moving this class to a lower level library allows
it to be freely used within LLDB.

Since this class is used in a lot of places in clang, and it used to be
in the clang namespace, it seemed appropriate to add it to the list of
adopted classes in LLVM.h to avoid prefixing all uses with "llvm::".

Also, I didn't find any tests specific for this class, so I wrote a
couple of quick ones for the more interesting bits of functionality.

Aaron Smith 010edd37f8 PDB support of function-level linking and splitted functions
Summary:
The patch adds support of splitted functions (when MSVC is used with PGO) and function-level linking feature.

SymbolFilePDB::ParseCompileUnitLineTable function relies on fact that ranges of compiled source files in the binary are continuous and don't intersect each other. The function creates LineSequence for each file and inserts it into LineTable, and implementation of last one relies on continuity of the sequence. But it's not always true when function-level linking enabled, e.g. in added input test file test-pdb-function-level-linking.exe there is xstring's std__basic_string_char_std__char_traits_char__std__allocator_char_____max_size (.00454820) between test-pdb-function-level-linking.cpp's foo (.00454770) and main (.004548F0).

To fix the problem this patch renews the sequence on each address gap.
