George Burgess IV 6ef8002c2c Replace most users of UnknownSize with LocationSize::unknown(); NFC 
Moving away from UnknownSize is part of the effort to migrate us to
LocationSizes (e.g. the cleanup promised in D44748).

This doesn't entirely remove all of the uses of UnknownSize; some uses
require tweaks to assume that UnknownSize isn't just some kind of int.
This patch is intended to just be a trivial replacement for all places
where LocationSize::unknown() will Just Work.

James Y Knight c0b28d55a7 llvm-ar: Darwin archive format fixes. 
* Support writing the DARWIN64 symbol table format.

* In darwin archives, emit a symbol table whenever requested, even
  when there are no members, as the apple linker will abort if given
  an archive without a symbol table.

Added tests for same, and also simplified and moved the GNU 64-bit
symbol table test into archive-symtab.test.

Sanjay Patel 05aadf885d [InstCombine] reverse 'trunc X to <N x i1>' canonicalization; 2nd try 
Re-trying r344082 because it unintentionally included extra diffs.

Original commit message:
icmp ne (and X, 1), 0 --> trunc X to N x i1

Ideally, we'd do the same for scalars, but there will likely be
regressions unless we add more trunc folds as we're doing here
for vectors.

The motivating vector case is from PR37549:
https://bugs.llvm.org/show_bug.cgi?id=37549

define <4 x float> @bitwise_select(<4 x float> %x, <4 x float> %y, <4 x float> %z, <4 x float> %w) {

  %c = fcmp ole <4 x float> %x, %y
  %s = sext <4 x i1> %c to <4 x i32>
  %s1 = shufflevector <4 x i32> %s, <4 x i32> undef, <4 x i32> <i32 0, i32 0, i32 1, i32 1>
  %s2 = shufflevector <4 x i32> %s, <4 x i32> undef, <4 x i32> <i32 2, i32 2, i32 3, i32 3>
  %cond = or <4 x i32> %s1, %s2
  %condtr = trunc <4 x i32> %cond to <4 x i1>
  %r = select <4 x i1> %condtr, <4 x float> %z, <4 x float> %w
  ret <4 x float> %r

}

Here's a sampling of the vector codegen for that case using
mask+icmp (current behavior) vs. trunc (with this patch):

Roman Lebedev 33d84c6dac [X86] Move X86DAGToDAGISel::matchBEXTRFromAnd() into X86ISelLowering 
Summary:
As discussed in [[ https://bugs.llvm.org/show_bug.cgi?id=38938 | PR38938 ]],
we fail to emit `BEXTR` if the mask is shifted.
We can't deal with that in `X86DAGToDAGISel` `before the address mode for the inc is selected`,
and we can't really do it in the normal DAGCombine, because we don't have generic `ISD::BitFieldExtract` node,
and if we simply turn the shifted mask into a normal mask + shift-left, it will be folded back.
So it would seem X86ISelLowering is the place to handle this.

This patch only moves the matchBEXTRFromAnd()
from X86DAGToDAGISel to X86ISelLowering.
It does not add support for the 'shifted mask' pattern.

Adding a new reduction pattern match for vectorizing code similar to TSVC s3111:

This patch adds support for fadd, fsub and fmull, as well as multiple
branches and different (but compatible) instructions (ex. add+sub) in
different branches.

I have forwarded to trunk, added fsub and fmul functionality and
additional tests, but the credit goes to Takahiro, who did most of the
actual work.

Francis Visoiu Mistrih 2e76cab47f Reland: [OptRemarks] Add library for parsing optimization remarks 
Add a library that parses optimization remarks (currently YAML, so based
on the YAMLParser).

The goal is to be able to provide tools a remark parser that is not
completely dependent on YAML, in case we decide to change the format
later.

It exposes a C API which takes a handler that is called with the remark
structure.

It adds a libLLVMOptRemark.a static library, and it's used in-tree by
the llvm-opt-report tool (from which the parser has been mostly moved
out).

Craig Topper df17244ffa Change the timestamp of llvmcache-foo file to meet the thinLTO prune policy 
The case will randomly fail if we test it with command "
while llvm-lit test/tools/gold/X86/cache.ll ; do true; done". It is because the llvmcache-foo file is younger than llvmcache-349F039B8EB076D412007D82778442BED3148C4E and llvmcache-A8107945C65C2B2BBEE8E61AA604C311D60D58D6. But due to timestamp precision reason their timestamp is the same. Given the same timestamp, the file prune policy is to remove bigger size file first, so mostly foo file is removed for its bigger size. And the files size is under threshold after deleting foo file. That's what test case expect.

However sometimes, the precision is enough to measure that timestamp of llvmcache-349F039B8EB076D412007D82778442BED3148C4E and llvmcache-A8107945C65C2B2BBEE8E61AA604C311D60D58D6 are smaller than foo, so llvmcache-349F039B8EB076D412007D82778442BED3148C4E and llvmcache-A8107945C65C2B2BBEE8E61AA604C311D60D58D6 are deleted first. Since the files size is still above the file size threshold after deleting the 2 files, the foo file is also deleted. And then the test case fails, because it expect only one file should be deleted instead of 3.

The fix is to change the timestamp of llvmcache-foo file to meet the thinLTO prune policy.

Zachary Turner 72148edc36 Create a SymbolFile plugin for cross-platform PDB access. 
The existing SymbolFilePDB only works on Windows, as it is written
against a closed-source Microsoft SDK that ships with their debugging
tools.

There are several reasons we want to bypass this and go straight to the
bits of the PDB, but just to list a few:

More room for optimization. We can't see inside the implementation of
the Microsoft SDK, so we don't always know if we're doing things in the
most efficient way possible. For example, setting a breakpoint on main
of a big program currently takes several seconds. With the
implementation here, the time is unnoticeable.
We want to be able to symbolize Windows minidumps even if not on
Windows. Someone should be able to debug Windows minidumps as if they
were on Windows, given that no running process is necessary.
This patch is a very crude first attempt at filling out some of the
basic pieces.

I've implemented FindFunctions, ParseCompileUnitLineTable, and
ResolveSymbolContext for a limited subset of possible parameter values,
which is just enough to get it to display something nice for the
breakpoint location.

I've added several tests exercising this functionality which are limited
enough to work on all platforms but still exercise this functionality.
I'll try to add as many tests of this nature as I can, but at some
point we'll need a live process.

For now, this plugin is enabled always on non-Windows, and by setting
the environment variable LLDB_USE_NATIVE_PDB_READER=1 on Windows.
Eventually, once it's at parity with the Windows implementation, we'll
delete the Windows DIA-based implementation.

extended loads and truncated stores to the same address so long as the
load is fully subsumed by the store.

Hexagon's swp-epilog-phis.ll and swp-memrefs-epilog1.ll test are
deleted as they've no longer seem to be relevant.

Sanjay Patel 6cca8af227 [x86] allow single source horizontal op matching (PR39195) 
This is intended to restore horizontal codegen to what it looked like before IR demanded elements improved in:
rL343727

As noted in PR39195:
https://bugs.llvm.org/show_bug.cgi?id=39195
...horizontal ops can be worse for performance than a shuffle+regular binop, so I've added a TODO. Ideally, we'd 
solve that in a machine instruction pass, but a quicker solution will be adding a 'HasFastHorizontalOp' feature
bit to deal with it here in the DAG.

Jonas Devlieghere fc51490baf Lift VFS from clang to llvm (NFC) 
This patch moves the virtual file system form clang to llvm so it can be
used by more projects.

Concretely the patch:
 - Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
 - Moves the corresponding unit test from clang to llvm.
 - Moves the vfs namespace from clang::vfs to llvm::vfs.
 - Formats the lines affected by this change, mostly this is the result of
   the added llvm namespace.

John Brawn c616a7236c [llvm-exegesis] Fix function return generation so it doesn't return register 0 
When fillMachineFunction generates a return on targets without a return opcode
(such as AArch64) it should pass an empty set of registers as the return
registers, not 0 which means register number zero.

Simon Pilgrim bc7b6251b6 [TargetLowering] SimplifyDemandedBits - rename demanded mask args. NFCI. 
Help stop bugs like rL343935 by making the 'original' DemandedBits arg more obviously not the mask that is actually used.
