On Darwin, if a test machine isn't set up for code-signing (see
docs/code-signing.txt), running check-lldb should use the system
debugserver instead of the unsigned one built in-tree. This makes it
possible to run lldb's test suite without having code-signing set up,
which is really convenient.

Due to an unfortunate difference between the open source test harness
and our internal harness, applying two @skip... decorators to this test
works in the internal build but not in the open source build.
I've tried another approach to skipping this test and tested it out with
the open source harness. Hopefully this sticks!

Summary:
LLDB's DumpDataExtractor was not prepared to handle PowerPC's long double type: PPCDoubleDouble.
As it is somewhat special, treating it as other regular float types resulted in getting wrong information about it.
In this particular case, llvm::APFloat::getSizeInBits(PPCDoubleDouble) was returning 0.
This caused the TestSetValues.py test to fail, because lldb would abort on an assertion failure on APInt(), because of the invalid size.
Since in the PPC case the value of item_byte_size was correct and the
getSizeInBits call was only added to support x87DoubleExtended
semantics, this restricts the usage of getSizeInBits to the x87
semantics.

In D40616 I (mistakenly) assumed that logging an llvm::Error would clear
it. This of course is only true if logging is actually enabled.
This fixes the assertion by manually clearing the error, but it raises
the point of whether we need a special error-clearing logging primitive.

This removes boilerplate for setting up a log channel and capturing the
output from some of the tests. I do this by moving the setup code into a
test fixture and adding a logAndTakeOutput utility function to log some
string and then retrieve it from the log.
I also use some googlemock goodies to simplify a couple of assertions.

Summary:
This commit is a combination of the following changes:
- Cache PDB's global scope (executable) in SymbolFilePDB
- Change naming of `cu` to `compiland` which is PDB specific
- Change ParseCompileUnitForSymIndex to ParseCompileUnitForUID.
Prefer using a common name `UID` instead of PDB's `System Index`
Adding one more argument `index` to this method, which is used to
specify the index of the compile unit in a cached compile unit array
- Add GetPDBCompilandByUID method to simply code
- Fix a bug in getting the source file name for a PDB compiland.
For some reason, PDBSymbolCompiland::getSourceFileName() could
return an empty name, so if that is true, we have to walk through all
source files of this compiland and determine the right source file
used to generate this compiland based on language indicated.
The previous implementation called PDBSession::findOneSourceFile
method to get its name for the compiland. This is not accurate since
the `one source file` found could be a header other than source file.

RemoveInvalidLocations was clearing out the m_locations in the
breakpoint by hand, and it wasn't also clearing the locations from
the address->location map, which confused us when we went to update
breakpoint locations.
I also made Breakpoint::ModulesChanged check the Location's Section
to make sure it hadn't been deleted. This shouldn't strictly be necessary,
but if the DynamicLoaderPlugin doesn't do it's job right (I'm looking at
you new Darwin DynamicLoader...) then it can end up leaving stale locations
on rerun. It doesn't hurt to clean them up here as a backstop.

This test stresses expression evaluation support for template functions.
Currently the support is rudimentary, and running this test causes assertion
failures in clang. This test cannot be XFAIL'ed because the test harness

# remove possibility to dereference nullptr during createMCAsmInfo invocation, that could lead to undefined behavior.

Summary:
Gdb servers like openocd may send many $O reply packets for the client to output during a qRcmd command sequence. Currently, lldb interprets the first O packet as an unexpected response. Besides generating no output, this causes lldb to get out of sync with future commands because it continues reading O packets from the first command as response to subsequent commands.
This patch handles any O packets during an qRcmd, treating the first non-O packet as the true response.

the previous fix did not work because of different const qualifications
on the envp pointer.
This should resolve that (and remove a couple of const_casts in the
process).
llvm-svn: 322187
Summary:
There was some confusion in the code about how to represent process
environment. Most of the code (ab)used the Args class for this purpose,
but some of it used a more basic StringList class instead. In either
case, the fact that the underlying abstraction did not provide primitive
operations for the typical environment operations meant that even a
simple operation like checking for an environment variable value was
several lines of code.
This patch adds a separate Environment class, which is essentialy a
llvm::StringMap<std::string> in disguise. To standard StringMap
functionality, it adds a couple of new functions, which are specific to
the environment use case:
- (most important) envp conversion for passing into execve() and likes.
Instead of trying to maintain a constantly up-to-date envp view, it
provides a function which creates a envp view on demand, with the
expectation that this will be called as the very last thing before
handing the value to the system function.
- insert(StringRef KeyEqValue) - splits KeyEqValue into (key, value)
pair and inserts it into the environment map.
- compose(value_type KeyValue) - takes a map entry and converts in back
into "KEY=VALUE" representation.
With this interface most of the environment-manipulating code becomes
one-liners. The only tricky part was maintaining compatibility in
SBLaunchInfo, which expects that the environment entries are accessible
by index and that the returned const char* is backed by the launch info
object (random access into maps is hard and the map stores the entry in
a deconstructed form, so we cannot just return a .c_str() value). To
solve this, I have the SBLaunchInfo convert the environment into the
"envp" form, and use it to answer the environment queries. Extra code is
added to make sure the envp version is always in sync.
(This also improves the layering situation as Args was in the Interpreter module
whereas Environment is in Utility.)

libcompression in debugserver by default (these API are only present
in macOS 10.11 and newer -- 10.11 was released c. Sep 2015).
I don't know if we have people / bots building lldb on older mac
releases; if this turns out to be a problem I will revert the change.
There are some parts of lldb (e.g. debugserer's ability to report
the OS version #) that only work with 10.10 and this changes the
behavior of lldb (whether the older or newer dyld interfaces are
used) so there is some importance to updating the min required
version.
