Summary:
Several changes were required for ThinLTO links involving bitcode
archive static libraries. With this patch clang/llvm bootstraps with
ThinLTO and gold.
The first is that the gold callbacks get_input_file and
release_input_file can normally be used to get file information for
each constituent bitcode file within an archive. However, these
interfaces lock the underlying file and can't be for each archive
constituent for ThinLTO backends where we get all the input files up
front and don't release any until after the backend threads complete.
However, it is sufficient to only get and release once per file, and
then each consituent bitcode file can be accessed via get_view. This
required saving some information to identify which file handle is the
"leader" for each claimed file sharing the same file descriptor, and
other information so that get_input_file isn't necessary later when
processing the backends.
Second, the module paths in the index need to distinguish between
different constituent bitcode files within the same archive file,
otherwise they will all end up with the same archive file path.
Do this by appending the offset within the archive for the start of the
bitcode file, returned by get_input_file when we claim each bitcode file,
and saving that along with the file handle.
Third, rather than have the function importer try to load a file based
on the module path identifier (which now contains a suffix to
distinguish different bitcode files within an archive), use a custom
module loader. This is the same approach taken in libLTO, and I am using
the support refactored into the new LTO.h header in r270509. The module
loader parses the bitcode files out of the memory buffers returned from
gold via the get_view callback and saved in a map. This also means that
we call the function importer directly, rather than add it to the pass
pipeline (which was in the plan to do already for other reasons).

This reapplies the previous patch with a modification which hopefully should fix

Richard Smith identified this in post commit review of r270466. The
string sections in particular (in the future, possibly all sections - so
I'm not going to bother pulling out just the string sections for the
extra lifetime handling right now) need to remain valid during
processing of all inputs so that elements of the DWPStringPool can be
looked up repeatedly without having to make in-memory copies of string
contents in the noncompressed case (more common in dwp+dwp merge steps
where the memory is a bigger problem because the files are larger).
Using the SmallVector (or any vector) a reallocation on push_back could
cause any of the nested SmallStrings in small mode to move in memory and
invalid pointers to their contents. Using a deque the SmallStrings will
never move around since no elements are removed from the container.

We have need to reuse this functionality, including making
additional generic stream types that are smarter about how and
when they copy memory versus referencing the original memory.
So all of these structures belong in the common library
rather than being pdb specific.

searching for external symbols, and fall back to the SymbolResolver::findSymbol
method if the former returns null.
This makes RuntimeDyld behave more like a static linker: Symbol definitions
from within the current module's "logical dylib" will be preferred to
external definitions. We can build on this behavior in the future to properly
support weak symbol handling.
Custom symbol resolvers that override the findSymbolInLogicalDylib method may
notice changes due to this patch. Clients who have not overridden this method
should generally be unaffected, however users of the OrcMCJITReplacement class
may notice changes.

different constants twice for compressed section:
Flags [

SHF_COMPRESSED (0x800)

The new PayloadString YAML field is populated with the data after load commands known to have strings as extra data.
The new ZeroPadBytes YAML field is a count of zero'd bytes after the end of the load command structure before the next command. This can apply anywhere in the file. MachO2YAML verifies that bytes are zero before populating this field, and YAML2MachO will add zero'd bytes.
The new PayloadBytes YAML field stores all bytes after the end of the load command structure before the next command if they are non-zero. This is a catch all for all unhandled bytes. If MachO2Yaml populates PayloadBytes it will not populate ZeroPadBytes, instead zero'd bytes will be in the PayloadBytes structure.

Add support to control where files for a distributed backend (the
individual index files and optional imports files) are created.
This is invoked with a new thinlto-prefix-replace option in the gold
plugin and llvm-lto. If specified, expects a string of the form
"oldprefix:newprefix", and instead of generating these files in the
same directory path as the corresponding bitcode file, will use a path
formed by replacing the bitcode file's path prefix matching oldprefix
with newprefix.
Also add a new replace_path_prefix helper to Path.h in libSupport.

Some of the tests fail with the new diagnostic handler, so they have to use the

Summary:
This code is intended to be used as part of LLD's PDB writing. Until
that exists, this is exposed via llvm-readobj for testing purposes.
Type stream merging uses the following algorithm:
- Begin with a new empty stream, and a new empty hash table that maps
from type record contents to new type index.
- For each new type stream, maintain a map from source type index to
destination type index.
- For each record, copy it and rewrite its type indices to be valid in
the destination type stream.
- If the new type record is not already present in the destination
stream hash table, append it to the destination type stream, assign it
the next type index, and update the two hash tables.
- If the type record already exists in the destination stream, discard
it and update the type index map to forward the source type index to
the existing destination type index.

It actually contains a serialized hash table along with fixed-sized
headers. This patch is not complete. It scans only till the end of
the stream and dump the header information. I'll write code to
de-serialize the hash table later.

This patch adds basic support for MachO::load_command. Load command types and sizes are encoded in the YAML and expanded back into MachO.
The YAML doesn't yet support load command structs, that is coming next. In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid.

This reverts commit r269428, as it breaks the LLDB build. We need to
understand how to change LLDB in the same way as LLC before landing this
again.

Without a diagnostic handler installed, llc's behaviour is to exit on the first
error that it encounters. This is very different from the behaviour of clang
and other front ends, which try to gather as many errors as possible before
exiting.
This commit adds a diagnostic handler to llc, allowing it to find and report
more than one error. The old behaviour is preserved under a flag (-exit-on-error).
Some of the tests fail with the new diagnostic handler, so they have to use the
new flag in order to run under the previous behaviour. Some of these are known
bugs, others need further investigation. Ideally, we should fix the tests and
remove the flag at some point in the future.

This change is the gold side of the change made in D17115 and clang
patch r261045 to add a ThinLTO specific pipeline that moves more of
the optimization to the backends.

In verbose mode, we emit a warning if the DWOId of a skeleton CU
mismatches the DWOId of the referenced module. This patch updates the
cached DWOId after a module has been loaded to the DWOId of the module
on disk (instead of storing the DWOId we expected to load). This
allows us to correctly emit the mismatch warning for all subsequent
object files that want to import the same module. This patch also
ensures both warnings are only emitted in verbose mode.

Dynamic table when printed shows uppercase tag/values.
This changes it to lower case when printing in GNU style
