Adrian Prantl 1ad655e255 Modernize the rest of the Find.* API (NFC)
This patch removes the size_t return value and the append parameter
from the remainder of the Find.* functions in LLDB's internal API. As
in the previous patches, this is motivated by the fact that these
parameters aren't really used, and in the case of the append parameter
were frequently implemented incorrectly.

Adrian Prantl bf9d84c014 Remove size_t return parameter from FindTypes
In r368345 I accidentally introduced a regression that would
over-report the number of matches found by FindTypes if the
DeclContext Filter was hit.

This patch simply removes the size_t return parameter altogether —
it's not that useful.

Jordan Rupprecht 6a253d378b [lldb] Qualify includes of Properties[Enum].inc files. NFC
Summary:
This is a bit more explicit, and makes it possible to build LLDB without
varying the -I lines per-directory.
(The latter is useful because many build systems only allow this to be
configured per-library, and LLDB is insufficiently layered to be split into
multiple libraries on stricter build systems).

(My comment on D65185 has some more context)

Jonas Devlieghere a8ea595509 [lldb] Also include the array definition in Properties.inc
Right now our Properties.inc only generates the initializer for the
options list but not the array declaration boilerplate around it. As the
array definition is identical for all arrays, we might as well also let
the Properties.inc generate it alongside the initializers.

Unfortunately we cannot do the same for enums, as there's this magic
ePropertyExperimental, which needs to come at the end to be interpreted
correctly. Hopefully we can get rid of this in the future and do the
same for the property enums.

Jonas Devlieghere 971f9ca612 Let tablegen generate property definitions
Property definitions are currently defined in a PropertyDefinition array
and have a corresponding enum to index in this array. Unfortunately this
is quite error prone. Indeed, just today we found an incorrect merge
where a discrepancy between the order of the enum values and their
definition caused the test suite to fail spectacularly.

Tablegen can streamline the process of generating the property
definition table while at the same time guaranteeing that the enums stay
in sync. That's exactly what this patch does. It adds a new tablegen
file for the properties, building on top of the infrastructure that
Raphael added recently for the command options. It also introduces two
new tablegen backends: one for the property definitions and one for
their corresponding enums.

It might be worth mentioning that I generated most of the tablegen
definitions from the existing property definitions, by adding a dump
method to the struct. This seems both more efficient and less error
prone that copying everything over by hand. Only Enum properties needed
manual fixup for the EnumValues and DefaultEnumValue fields.

Jonas Devlieghere 63e5fb76ec [Logging] Replace Log::Printf with LLDB_LOG macro (NFC)
This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.

So instead of writing:

  if (log)
    log->Printf("%s\n", str);

You'd write:

  LLDB_LOG(log, "%s\n", str);

This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.

  find . -type f -name '*.cpp' -exec \
  sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +

Jan Kratochvil 8c82c41262 [lldb] [test] Extend D55859 symbols.enable-external-lookup=false for more testcases
D55859 <https://reviews.llvm.org/D55859> has no effect for some of the
testcases so this patch extends it even for (all?) other testcases known to me.
LLDB was failing when LLDB prints errors reading system debug infos
(`*-debuginfo.rpm`, DWZ-optimized) which should never happen as LLDB testcases
should not be affected by system debug infos.

`lldb/packages/Python/lldbsuite/test/api/multithreaded/driver.cpp.template` is
using only SB API which does not expose `ModuleList` so I had to call
`HandleCommand()` there.

`lldb-test.cpp` could also use `HandleCommand` and then there would be no need
for `ModuleListProperties::SetEnableExternalLookup()` but I think it is cleaner
with API and not on based on text commands.

Jason Molenda 1724a179e7 Rename Target::GetSharedModule to Target::GetOrCreateModule.
Add a flag to control whether the ModulesDidLoad notification is
called when a module is added.  If the notifications are disabled,
the caller must call ModulesDidLoad after adding all the new modules,
but postponing this notification until they're all batched up can
allow for better efficiency than notifying one-by-one.

Change the name of the ModuleList notifier functions that a subclass
can implement to start with 'Notify' to make it clear what they are.
Add a NotifyModulesRemoved.

Add header documentation for the changed/updated methods.

Added defaulted-value 'notify' argument to ModuleList Append,
AppendIfNeeded, and Remove because callers working with a local
ModuleList don't have an obvious idea of what notify means in this
context.  When the ModuleList is a part of the Target class, the
notify behavior matters.

DynamicLoaderDarwin has been updated so that libraries being
added/removed are correctly batched up before notifications are
sent.  Added the TestModuleLoadedNotifys.py test to run on 
Darwin to test this.

Adrian Prantl 0e4c482124 Pass ConstString by value (NFC)
My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.

ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

Zachary Turner 80552918a9 Move Host/Symbols.cpp to Symbols/LocateSymbolFile.cpp
Given that we have a target named Symbols, one wonders why a
file named Symbols.cpp is not in this target.  To be clear,
the functions exposed from this file are really focused on
*locating* a symbol file on a given host, which is where the
ambiguity comes in.  However, it makes more sense conceptually
to be in the Symbols target. While some of the specific places
to search for symbol files might change depending on the Host,
this is not inherently true in the same way that, for example,
"accessing the file system" or "starting threads" is
fundamentally dependent on the Host.

PDBs, for example, recently became a reality on non-Windows platforms,
and it's theoretically possible that DSYMs could become a thing on non
MacOSX platforms (maybe in a remote debugging scenario). Other types of
symbol files, such as DWO, DWP, etc have never been tied to any Host
platform anyway.

After this patch, there is only one remaining dependency from
Host to Target.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Zachary Turner 576495e67b [SymbolFile] Remove SymbolContext parameter from FindTypes.
This parameter was only ever used with the Module set, and
since a SymbolFile is tied to a module, the parameter turns
out to be entirely unnecessary.  Furthermore, it doesn't make
a lot of sense to ask a caller to ask SymbolFile which is tied
to Module X to find types for Module Y, but that possibility
was open with the previous interface.  By removing this
parameter from the API, it makes it harder to use incorrectly
as well as easier for an implementor to understand what it
needs to do.

Jan Kratochvil 4c993ce187 symbols.enable-external-lookup=false on all hosts (not just OSX)
There is already in use:
	lit/lit-lldb-init:
		settings set symbols.enable-external-lookup false
	packages/Python/lldbsuite/test/lldbtest.py:
		self.runCmd('settings set symbols.enable-external-lookup false')

But those are not in effect during MI part of the testsuite. Another problem is
that symbols.enable-external-lookup (read by GetEnableExternalLookup) has been
currently read only by LocateMacOSXFilesUsingDebugSymbols and therefore it had
no effect on Linux.

On Red Hat platforms (Fedoras, RHEL-7) there is DWZ in use and so
MiSyntaxTestCase-test_lldbmi_output_grammar FAILs due to:
	AssertionError: error: inconsistent pattern ''^.+?\n'' for state 0x5f
	(matched string: warning: (x86_64) /lib64/libstdc++.so.6 unsupported
	DW_FORM values: 0x1f20 0x1f21
It is the only testcase with this error. It happens due to:
	(lldb) target create "/lib64/libstdc++.so.6"
	Current executable set to '/lib64/libstdc++.so.6' (x86_64).
	(lldb) b main
	warning: (x86_64) /lib64/libstdc++.so.6 unsupported DW_FORM values: 0x1f20 0x1f21
	Breakpoint 1: no locations (pending).
	WARNING:  Unable to resolve breakpoint to any actual locations.
which happens only with gcc-base-debuginfo rpm installed (similarly for other packages).

It should also speed up the testsuite as it no longer needs to read
/usr/lib/debug symbols which have no effect (and should not have any effect) on
the testsuite results.

This patch extends the FileSystem class with a bunch of functions that
are currently implemented as methods of the FileSpec class. These
methods will be removed in future commits and replaced by calls to the
file system.

The new functions are operated in terms of the virtual file system which
was recently moved from clang into LLVM so it could be reused in lldb.
Because the VFS is stateful, we turned the FileSystem class into a
singleton.
