The problem was that if the platform wasn't compatible with the current file in the "target create" command, it wasn't finding a platform that was like it used to.
Also, the currently selected platform was being used upload the file _before_ the target was created which was incorrect as "target create a.out" might switch platforms if its architecture doesn't match, so I moved the uploading to happen after the target was created so we use the right platform (the one in the target, not the selected one).
llvm-svn: 227380
The change was made so we could re-use a platform if one was already created instead of creating a new one, but it would fail in the above case. To fix this, if we have a selected platform, we verify that the platform matches the current platform before we try to re-use it. We do this by asking the OptionGroupPlatform if the platform matches. If so, it returns true and we don't create a new platform, else we do.

And since enough of these are doing the right thing, add a test case to verify we are doing the right thing with freeze drying ObjC object types
Fixes rdar://18092770
llvm-svn: 227282
Namely, this commit provides an actual implementation of how to retrieve the byte size in a sane way for an ObjC class, by scanning ivar offsets and byte sizes, figuring out the farthest-from-base ivar, and adding its byte size to that
Still NFC
llvm-svn: 227277
This is necessary because the byte size of an ObjC class type is not reliably statically knowable (e.g. because superclasses sit deep in frameworks that we have no debug info for)
The lack of reliable size info is a problem when trying to freeze-dry an ObjC instance (not the pointer, the pointee)
This commit lays the foundation for having language runtimes help in figuring out byte sizes, and having ClangASTType ask for runtime help
No feature change as no runtime actually implements the logic, and nowhere is an ExecutionContext passed in yet

Without this overload, attempts to edit the value of a variable with synthetic children enabled would change the value inside the synthetic ValueObject, but not propagate the changes to the underlying storage, hence resulting in no write for any meaningful purpose

Other platforms may benefit from something similar if issues arise. The
libedit library doesn't explicitly initialize the curses termcap library,
which it gets away with until TERM is set to VT100 where it stumbles over
an implementation assumption that may not exist on other platforms.

When you create a target, it tries to look for the platform's list
of supported architectures for a match. The match it finds can
contain specific triples, like i386-pc-windows-msvc. Later, we
overwrite this value with the most generic triple that can apply
to any platform with COFF support, causing some of the fields of
the triple to get overwritten.
This patch changes the behavior to only merge in values from the COFF
triple if the fields of the matching triple were unknown/unspecified
to begin with.
This fixes load address resolution on Windows, since it enables the
DynamicLoaderWindows to be used instead of DynamicLoaderStatic.

inferring the function signature. This works well where the ABI doesn't
distinguish between variadic and fixed argument lists, but on arm64 the
calling conventions differ. The default assumption works for fixed argument
lists, but variadic functions require explicit prototypes to be called.
By far the most common case where this is an issue is when attempting to use
printf(). This change augments the default expression prefix to include a
working variadic prototype for the function.

Make sure that the host uses the connect://hostname to connect to both
the lldb-platform and the lldb-gdbserver rather than what the platform
reports as the hostname of the lldb-gdbserver

Most of the time, we can use context information just fine to choose a language (i.e. the language of the frame that the root object was defined in, if any); but in some cases, synthetic children may be fabricated as root frame-less entities, and then we wouldn't know any better
This patch allows (internal) synthetic child providers to set a display language on the children they generate, should they so choose
