Zachary Turner b2fef1a0b0 Add support for various C++14 demanglings.
Mostly this includes <auto> and <decltype-auto> return values.
Additionally, this fixes a fairly obscure back-referencing bug
that was encountered in one of the C++14 tests, which is that
if you have something like Foo<&bar, &bar> then the `bar`
forms a backreference.

Zachary Turner 38d2edd60d [MS Demangler] Add output flags to all function calls.
Previously we had a FunctionSigFlags, but it's more flexible
to just have one set of output flags that apply to the entire
process and just pipe the entire set of flags through the
output process.

This will be useful when we start allowing the user to customize
the outputting behavior.

Reid Kleckner 689f773317 [codeview] Clean up machinery for deferring .cv_loc emission
Now that we create the label at the point of the directive, we don't
need to set the "current CV location", and then later when we emit the
next instruction, create a label for it and emit it.

DWARF still defers the labels used in .debug_loc until the next
instruction or value, for reasons unknown.

Zhaoshi Zheng 35818e2789 [QTOOL-37352] Consider isLegalAddressingImm in Constant Hoisting
In Thumb1, legal imm range is [0, 255] for ADD/SUB instructions. However, the
legal imm range for LD/ST in (R+Imm) addressing mode is [0, 127]. Imms in
[128, 255] are materialized by mov R, #imm, and LD/STs use them in (R+R)
addressing mode.

This patch checks if a constant is used as offset in (R+Imm), if so, it checks
isLegalAddressingMode passing the constant value as BaseOffset.

Reid Kleckner c8074aa654 [codeview] Emit labels for .cv_loc immediately
Previously we followed the DWARF implementation, which waits until the
next instruction or data to emit the label to use in the .debug_loc
section. We might want to consider re-evaluating that design choice as
well, since it means the .loc skips alignment padding, for better or
worse.

This was the most minimal fix I could come up with, but we should be
able to do a lot of cleanups now that we don't need to save a pending CV
location on the CodeViewContext. I plan to do those next, but this
immediately fixes an assertion for some of our users.

Lang Hames 6cadc7c06b [ORC] Replace lookupFlags in JITSymbolResolver with getResponsibilitySet.
The new method name/behavior more closely models the way it was being used.
It also fixes an assertion that can occur when using the new ORC Core APIs,
where flags alone don't necessarily provide enough context to decide whether
the caller is responsible for materializing a given symbol (which was always
the reason this API existed).

The default implementation of getResponsibilitySet uses lookupFlags to determine
responsibility as before, so existing JITSymbolResolvers should continue to
work.

Craig Topper 9401fd0ed2 [X86] Add intrinsics for KADD instructions
These are intrinsics for supporting kadd builtins in clang. These builtins are already in gcc to implement intrinsics from icc. Though they are missing from the Intel Intrinsics Guide.

This instruction adds two mask registers together as if they were scalar rather than a vXi1. We might be able to get away with a bitcast to scalar and a normal add instruction, but that would require DAG combine smarts in the backend to recoqnize add+bitcast. For now I'd prefer to go with the easiest implementation so we can get these builtins in to clang with good codegen.

Aditya Nandakumar 6b4d343e13 [GISel]: Add missing opcodes for overflow intrinsics
https://reviews.llvm.org/D51197

Currently, IRTranslator (and GISel) seems to be arbitrarily picking
which overflow intrinsics get mapped into opcodes which either have a
carry as an input or not.
For intrinsics such as Intrinsic::uadd_with_overflow, translate it to an
opcode (G_UADDO) which doesn't have any carry inputs (similar to LLVM
IR).

This patch adds 4 missing opcodes for completeness - G_UADDO, G_USUBO,
G_SSUBE and G_SADDE.

Matt Morehouse c6fff3b6f5 [libFuzzer] Port to Windows
Summary:
Port libFuzzer to windows-msvc.
This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well.
It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch.
It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.

Stella Stamenova 8f8832d261 [lit, shtest-timeout] Always use an internal shell for the shtest-timeout to diagnose buildbot failures
Summary:
Right now this test is failing on the builtbots on Windows but we have a very similar setup where the test passes. The test is meant to test that specifying a timeout works correctly by running an infnite loop and having it timeout - on the buildbot, the infinite loop doesn't actually execute. This change runs all of the tests in the set using an internal shell rather than an external shell. I expect this will make the test pass which means that either the way the external shell is invoked or the external shell setup on the buildbots is not correct. Regardless of whether the test passes with this change, we'll need to undo this change and have a real fix.

@gkistanova was able to get logs from the buildbot to rule out a number of theories as to why this test is failing, but they didn't have enough information to confirm exactly what the issue is. The purpose of this change is to narrow it down, but if someone has a local repro and can aid in debugging, that would make it much speedier (and less prone to making the bots fail).

Simon Pilgrim 6a92b5e1e2 [TableGen] CodeGenDAGPatterns::GenerateVariants - basic caching of matching predicates
CodeGenDAGPatterns::GenerateVariants is a costly function in many tblgen commands (33.87% of the total runtime of x86 -gen-dag-isel), and due to the O(N^2) nature of the function, there are a high number of repeated comparisons of the pattern's vector<Predicate>.

This initial patch at least avoids repeating these comparisons for every Variant in a pattern. I began investigating caching all the matches before entering the loop but hit issues with how best to store the data and how to update the cache as patterns were added.

Saves around 15secs in debug builds of x86 -gen-dag-isel.

David Bolvansky c1b27b562b [Inliner] Attribute callsites with inline remarks
Summary:
Sometimes reading an output *.ll file it is not easy to understand why some callsites are not inlined. We can read output of inline remarks (option --pass-remarks-missed=inline) and try correlating its messages with the callsites.

An easier way proposed by this patch is to add to every callsite processed by Inliner an attribute with the latest message that describes the cause of not inlining this callsite. The attribute is called //inline-remark//. By default this feature is off. It can be switched on by the option //-inline-remark-attribute//.

For example in the provided test the result method //@test1// has two callsites //@bar// and inline remarks report different inlining missed reasons:
  remark: <unknown>:0:0: bar not inlined into test1 because too costly to inline (cost=-5, threshold=-6)
  remark: <unknown>:0:0: bar not inlined into test1 because it should never be inlined (cost=never): recursive

It is not clear which remark correspond to which callsite. With the inline remark attribute enabled we get the reasons attached to their callsites:
  define void @test1() {
    call void @bar(i1 true) #0
    call void @bar(i1 false) #2
    ret void
  }
  attributes #0 = { "inline-remark"="(cost=-5, threshold=-6)" }
  ..
  attributes #2 = { "inline-remark"="(cost=never): recursive" }
