[DebugInfo] Align comments in debug_loc section
Summary:
This commit updates the BufferByteStreamer, used by DebugLocStream
to buffer bytes/comments to put in the debug_loc section, to
make sure that the Buffer and Comments vectors are synced.
Previously, when an SLEB128 or ULEB128 was emitted together with
a comment, the vectors could be out-of-sync if the LEB encoding
added several entries to the Buffer vectors, while we only added
a single entry to the Comments vector.
The goal with this is to get the comments in the debug_loc
section in the .s file correctly aligned.
Example (using ARM as target):
Instead of
.byte 144 @ sub-register DW_OP_regx
.byte 128 @ 256
.byte 2 @ DW_OP_piece
.byte 147 @ 8
.byte 8 @ sub-register DW_OP_regx
.byte 144 @ 257
.byte 129 @ DW_OP_piece
.byte 2 @ 8
.byte 147 @
.byte 8 @
we now get
.byte 144 @ sub-register DW_OP_regx
.byte 128 @ 256
.byte 2 @
.byte 147 @ DW_OP_piece

Besides the bug of omitting the inverse transform of max(~a, ~b) --> ~min(a, b),
the use checking and operand creation were off. We were potentially creating
repeated identical instructions of existing values. This led to infinite
looping after I added the extra folds.
By using the simpler m_Not matcher and not creating new 'not' ops for a and b,
we avoid that problem. It's possible that not using IsFreeToInvert() here is
more limiting than the simpler matcher, but there are no tests for anything
more exotic. It's also possible that we should relax the use checking further

[Option] Add 'findNearest' method to catch typos
Summary:
Add a method `OptTable::findNearest`, which allows users of OptTable to
check user input for misspelled options. In addition, have llvm-mt
check for misspelled options. For example, if a user invokes
`llvm-mt /oyt:foo`, the error message will indicate that while an
option named `/oyt:` does not exist, `/out:` does.
The method ports the functionality of the `LookupNearestOption` method
from LLVM CommandLine to libLLVMOption. This allows tools like Clang
and Swift, which do not use CommandLine, to use this functionality to
suggest similarly spelled options.
As room for future improvement, the new method as-is cannot yet properly suggest
nearby "joined" options -- that is, for an option string "-FozBar", where
"-Foo" is the correct option name and "Bar" is the value being passed along
with the misspelled option, this method will calculate an edit distance of 4,
by deleting "Bar" and changing "z" to "o". It should instead calculate an edit
distance of just 1, by changing "z" to "o" and recognizing "Bar" as a
value. This commit includes a disabled test that expresses this limitation.

This allows a consumer to understand whether a composite data type is

following two types:
// S is not trivially copyable because of the explicit destructor.
struct S {

// T is a POD type.

[ORC] Add new core ORC APIs (Core.h/Core.cpp): VSO, AsynchronousSymbolQuery and
SymbolSource.
These new APIs are a first stab at tackling some current shortcomings of ORC,
especially in performance and threading support.
VSO (Virtual Shared Object) is a symbol table representing the symbol
definitions of a set of modules that behave as if they had been statically
linked together into a shared object or dylib. Symbol definitions, either
pre-defined addresses or lazy definitions, can be added and queries for symbol
addresses made. The table applies the same linkage strength rules that static
linkers do when constructing a dylib or shared object: duplicate definitions
result in errors, strong definitions override weak or common ones. This class
should improve symbol lookup speed by providing centralized symbol tables (as
compared to the findSymbol implementation in the in-tree ORC layers, which
maintain one symbol table per object file / module added).
AsynchronousSymbolQuery is a query for the addresses of a set of symbols.
Query results are returned via a callback once they become available. Querying
for a set of symbols, rather than one symbol at a time (as the current lookup
scheme does) the JIT has the opportunity to make better use of available
resources (e.g. by spawning multiple jobs to materialize the requested symbols
if possible). Returning results via a callback makes queries asynchronous, so
queries from multiple threads of JIT'd code can proceed simultaneously.
SymbolSource represents a source of symbol definitions. It is used when
adding lazy symbol definitions to a VSO. Symbol definitions can be materialized
when needed or discarded if a stronger definition is found. Materializing on
demand via SymbolSources should (eventually) allow us to remove the lazy
materializers from JITSymbol, which will in turn allow the removal of many
current error checks and reduce the number of RPC round-trips involved in
materializing remote symbols. Adding a discard function allows sources to
discard symbol definitions (or mark them as available_externally), reducing the
amount of redundant code generated by the JIT for ODR symbols.

[JumpThreading] Preservation of DT and LVI across the pass
Summary:
See D37528 for a previous (non-deferred) version of this
patch and its description.
Preserves dominance in a deferred manner using a new class
DeferredDominance. This reduces the performance impact of
updating the DominatorTree at every edge insertion and
deletion. A user may call DDT->flush() within JumpThreading
for an up-to-date DT. This patch currently has one flush()
at the end of runImpl() to ensure DT is preserved across
the pass.
LVI is also preserved to help subsequent passes such as
CorrelatedValuePropagation. LVI is simpler to maintain and
is done immediately (not deferred). The code to perfom the
preversation was minimally altered and was simply marked
as preserved for the PassManager to be informed.
This extends the analysis available to JumpThreading for
future enhancements. One example is loop boundary threading.

Teach InlineCost about address spaces
Summary:
I basically copied this patch from here:
https://reviews.llvm.org/D1251
But I skipped some of the refactoring to make the patch more clean.
The new outer3/inner3 test case in ptr-diff.ll triggers the
following assert without this patch:
lib/IR/Constants.cpp:1834: static llvm::Constant *llvm::ConstantExpr::getCompare(unsigned short, llvm::Constant *, llvm::Constant *, bool): Assertion `C1->getType() == C2->getType() && "Op types should be identical!"' failed.
The other new test cases makes sure that there is code coverage
for all modifications in InlineCost.cpp (getting different values
due to not fetching sizes for address space zero). I only guarantee
code coverage for those tests. The tests are not written in a way
that they would break if not having the corrections in
InlineCost.cpp. I found it quite hard to fine tune the tests into
getting different results based on the pointer sizes (except for
the test case where we hit an assert if not teaching InlineCost
about address spaces).

Add assertion on DT availability during LI update in UpdateAnalysisInformation
This came up during discussions in llvm-commits for
rL321653: Check for unreachable preds before updating LI in
UpdateAnalysisInformation
The assert provides hints to passes to require both DT and LI if we plan on
updating LI through this function.

[Docs] Add Contributing page.
This new page acts as an entry point for (new) contributors to LLVM and
provides information about
* What to contribute
* How to submit a patch
* Where to start to learn more about LLVM's architecture and internals.
This version of the page duplicates some information from the
DeveloperPolicy and Phabricator pages. Subsequent changes should work
towards moving information for new developers to this page, where it
makes sense.

[ARM GlobalISel] Fix selection of pointer constants
We used to handle G_CONSTANT with pointer type by forcing the type of
the result register to s32 and then letting TableGen handle it.
Unfortunately, setting the type only works for generic virtual
registers, that haven't yet been constrained to a register class (e.g.
those used only by a COPY later on). If the result register has already
been constrained as a use of a previously selected instruction, then
setting the type will assert.
It would be nice to be able to teach TableGen to select pointer
constants the same as integer constants, but since it's such an edge
case (at the moment the only pointer constant that we're generally
interested in is 0, and that is mostly used for comparisons and selects,
which are also not supported by TableGen) it's probably not worth the
effort right now. Instead, handle pointer constants with some trivial
handwritten code.
