Nico Weber 90d6ed144c TarWriter: Only use 137 of the 155 prefix bytes.
This makes lld's --reproduce output more compatible with tar 1.13 and
before.  This is a very old version of tar, but it's the version in
both gnuwin and unxutils, and the cost for supporting them are very
low, so we might as well just do that.

Fangrui Song 3c9c9c1768 [llvm-objdump] Print target address with evaluateMemoryOperandAddress()
D63847 added `MCInstrAnalysis::evaluateMemoryOperandAddress()`. This patch
leverages the feature to print the target addresses for evaluable instructions.

```
-400a: movl 4080(%rip), %eax
+400a: movl 4080(%rip), %eax  # 5000 <data1>
```

This patch also deletes `MIA->isCall(Inst) || MIA->isUnconditionalBranch(Inst) || MIA->isConditionalBranch(Inst)`
which is used to guard `MCInstrAnalysis::evaluateBranch()`

Pavel Labath 18e96a31fe [lldb/unittests] Skip IPv6 test on systems which don't have IPv6 configured
Sadly IPv6 is still not present anywhere. The test was attempting to
detect&skip such hosts, but the way it did that (essentially, by calling
getaddrinfo) meant that it only detected hosts which have IPv6 support
completely compiled out. It did not do anything about hosts which have
it compiled in, but lack runtime configuration even for the ::1 loopback
address.

This patch changes the detection logic to use a new method. It does it
by attempting to bind a socket to the appropriate loopback address. That
should ensure the hosts loopback interface is fully set up. In an effort
to avoid silently skipping the test on too many hosts, the test is
fairly strict about the kind of error it expects in these cases -- it
will only skip the test when receiving EADDRNOTAVAIL. If we find other
error codes that can be reasonably returned in these situations, we can
add more of them.

The (small) change in TCPSocket.cpp is to ensure that the code correctly
propagates the error received from the OS.

Louis Dionne a486edd03a [libc++abi] Assume that libcxx is checked out in the Apple build script
Instead of using the libc++ headers provided alongside the toolchain,
use those in the sibling libcxx directory that we know is checked out.
Before the days of the monorepo, we couldn't assume that the libc++
repository was present when building libcxxabi. Since we can now make
that assumption, it's always better to use the version of libc++ that
is in lockstep with libc++abi, to avoid subtle bugs.

`getHasRegParm()` was working under the assumption that the RegParm
bits are the last field, which is no longer true, after adding the
`NoCfCheck` and `CmseNSCall` fields.

Louis Dionne 6d58030c8c [libc++] Create a small DSL for defining Lit features and parameters
This allows defining Lit features that can be enabled or disabled based
on compiler support, and parameters that are passed on the command line.

The main benefits are:
- Feature detection is entirely based on the substitutions provided in
  the TestingConfig object, which is simpler and decouples it from the
  complicated compiler emulation infrastructure.
- The syntax is declarative, which makes it easy to see what features
  and parameters are accepted by the test suite. This is significantly
  less entangled than the current config.py logic.
- Since feature detection is based on substitutions, it works really
  well on top of the new format, and custom Lit configurations can be
  created easily without being based on `config.py`.

```

AssertionError: False is not True : Stopped at breakpoint in exec'ed process.
Config=x86_64-/Users/buildslave/jenkins/workspace/lldb-cmake/lldb-build/bin/clang-11
```

I don't know why the test program is failing and I couldn't reproduce this problem on my own.
This patch is a stab in the dark that just tries to make the test code more similar to code which
we would expect in a user program to make whatever part of macOS happy that is currently
not liking our code.

The actual changes are:
* We pass in argv[0] that is describing otherprog path instead of the current argv[0].
* We pass in a non-null envp (which anyway doesn't seem to be allowed on macOS man page).

Matthias Gehre 145dcef8bd [clang-tidy] modernize-use-using: Fix broken fixit with InjectedClassName
Summary:
Before this PR, `modernize-use-using` would transform the typedef in
```
template <int A>
struct InjectedClassName {
  typedef InjectedClassName b;
};
```
into `using b = InjectedClassName<A>;` and
```
template <int>
struct InjectedClassNameWithUnnamedArgument {
  typedef InjectedClassNameWithUnnamedArgument b;
};
```
into `using b = InjectedClassNameWithUnnamedArgument<>;`.
The first fixit is surprising because its different than the code
before, but the second fixit doesn't even compile.

This PR adds an option to the TypePrinter to print InjectedClassNameType without
template parameters (i.e. as written).

Tres Popp 2d2d696137 [MLIR] Propagate input side effect information
Summary:
Previously operations like std.load created methods for obtaining their
effects but did not inherit from the SideEffect interfaces when their
parameters were decorated with the information. The resulting situation
was that passes had no information on the SideEffects of std.load/store
and had to treat them more cautiously. This adds the inheritance
information when creating the methods.

As a side effect, many tests are modified, as they were using std.load
for testing and this oepration would be folded away as part of pattern
rewriting. Tests are modified to use store or to reutn the result of the
std.load.
