There's currently no raw_ostream &operator<<(SimpleValueType); provided by LLVM. It could be added by refactoring utils/TableGen/CodeGenTarget.cpp:getEnumName, but that's much more work than fixing the build.

The root of the problem was that findMainViewFileID(File, Function)
could return some ID for any given file, even though that file
was not the main file for that function.
This patch ensures that the result of this function is conformed
with the result of findMainViewFileID(Function).

Three problems:
1. <future> can't be easily used. If you must use it, see
include/Support/ThreadPool.h for how.
2. constexpr problems, even after 266588.
3. Move assignment operators can't be defaulted in MSVC2013.

Summary:
When clang is given -save-temps or -via-file-asm, any inline assembly in
the source is parsed twice. Once by the compiler, and again by the
assembler. We must take care to ensure that this doesn't lead to
double-filling delay slots.

Summary:
This will allows us to eliminate some magic numbers from the offset operand of
branch instructions in favour of symbols and makes it possible to avoid
double-filling delay slots when clang is given -save-temps.
parseDirectiveCpRestore() is calling isIntegratedAssemblerRequired() for the
moment since correctly pushing the generation of these instructions into the
ELF target streamer is tricky enough to warrant a separate patch.

Removed some unused headers, replaced some headers with forward class declarations.
Found using simple scripts like this one:
clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap'

asynchronous call/handle. Also updates the ORC remote JIT API to use the new
scheme.
The previous version of the RPC tools only supported void functions, and
required the user to manually call a paired function to return results. This
patch replaces the Procedure typedef (which only supported void functions) with
the Function typedef which supports return values, e.g.:
Function<FooId, int32_t(std::string)> Foo;
The RPC primitives and channel operations are also expanded. RPC channels must
support four new operations: startSendMessage, endSendMessage,
startRecieveMessage and endRecieveMessage, to handle channel locking. In
addition, serialization support for tuples to RPCChannels is added to enable
multiple return values.
The RPC primitives are expanded from callAppend, call, expect and handle, to:
appendCallAsync - Make an asynchronous call to the given function.
callAsync - The same as appendCallAsync, but calls send on the channel when
done.
callSTHandling - Blocking call for single-threaded code. Wraps a call to
callAsync then waits on the result, using a user-supplied
handler to handle any callbacks from the remote.
callST - The same as callSTHandling, except that it doesn't handle
callbacks - it expects the result to be the first return.
expect and handle - as before.
handleResponse - Handle a response from the remote.
waitForResult - Wait for the response with the given sequence number to arrive.

Cache the result of mapping metadata nodes between instances of IRLinker
(i.e., for the lifetime of IRMover). There shouldn't be any real
functional change here, but this should give a major speedup. I had
loaned this to Mehdi when he tested performance of r266446, and the two
patches together gave a 10x speedup in metadata mapping.

This catches two nullptr insertions into the ValueMap I missed in
r266567. I missed CloneFunction becuase it never calls RemapInstruction
directly. Here's one of the still-failing bots:
http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/builds/11496
llvm-svn: 266570
Add an assertion to ValueMapper that prevents double-scheduling of
GlobalValues to remap, and fix the one place it happened. There are
tons of tests that fail with this assertion in place and without the
code change, so I'm not adding another.
Although it looks related, r266563 was, indeed, removing dead code.
AFAICT, this cross-file double-scheduling started in r266510 when the
cross-file recursion was removed.
llvm-svn: 266569
Apparently there isn't test coverage for all of these. I'd appreciate
if someone with could reproduce and send me something to reduce, but for
now I've just looked for users of RemapInstruction and MapValue and
ensured they don't accidentally insert nullptr. Here is one of the
bootstraps that caught:
http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/builds/11494
llvm-svn: 266567
As a follow-up to r123058, assert that there are no null mappings in the
ValueMap instead of just ignoring them when they are there. There were
a couple of accidental insertions in CloneFunction so I cleaned those up
(caught by testcases).

This required changing several places to print VT enums as strings instead of raw ints since the proper method to use to print became ambiguous. This is probably an improvement anyway.
This also appears to save ~8K from an x86 self host build of llc.

There's a hole in the verifier right now: if a module has no compile
units, it never checks that all the string-based DITypeRefs get
resolved. As a result, this testcase didn't fail the verifier, even
there were references to `!"has-uuid"` instead of `!"uuid"` (the former
was a composite type's 'name:' field, the latter its 'identifier:'
field).
I'm currently working on removing string-based type refs entirely, and
this testcase started failing (because the upgrade script can't resolve
the type refs). Rather than fixing the (about-to-be-removed) hole in
the verifier, I'm just going to fix the test so that my upgrade script
handles it.
llvm-svn: 266553
Fix a couple of places in the Verifier that call `getScope()` instead of
`getRawScope()`. Both DIDerivedType::getScope and
DICompositeType::getScope return a DITypeRef right now (which wraps a
Metadata*) so I don't think there's currently an observable bug. I
found this because a future commit that will change them to cast to
DIScope*.

I accidentally replaced `mayBeOverridden` with `!isInterposable`.
Remove the negation and add a test case that would've caught this.

Rather than relying on the structural equivalence of DICompositeType to
merge type definitions, use an explicit map on the LLVMContext that
LLParser and BitcodeReader consult when constructing new nodes.
Each non-forward-declaration DICompositeType with a non-empty
'identifier:' field is stored/loaded from the type map, and the first
definiton will "win".
This map is opt-in: clients that expect ODR types from different modules
to be merged must call LLVMContext::ensureDITypeMap.
- Clients that just happen to load more than one Module in the same
LLVMContext won't magically merge types.
- Clients (like LTO) that want to continue to merge types based on ODR
identifiers should opt-in immediately.
I have updated LTOCodeGenerator.cpp, the two "linking" spots in
gold-plugin.cpp, and llvm-link (unless -disable-debug-info-type-map) to
set this.
With this in place, it will be straightforward to remove the DITypeRef
concept (i.e., referencing types by their 'identifier:' string rather
than pointing at them directly).
