to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This is a follow-up to r331272.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

The existing YAML Output::scalarString code path includes a partial and
incorrect implementation of YAML escaping logic. In particular, the logic put
in place in rL321283 escapes non-printable bytes only if they are not part of a
multibyte UTF8 sequence; implicitly this means that all multibyte UTF8
sequences -- printable and non -- are passed through verbatim.
The simplest solution to this is to direct the Output::scalarString method to
use the standalone yaml::escape function, and this _almost_ works, except that
the existing code in that function _over_ escapes: any multibyte UTF8 sequence
is escaped, even printable ones. While this is permitted for YAML, it is also
more aggressive (and hard to read for non-English locales) than necessary,
and the entire point of rL321283 was to back off such aggressive over-escaping.
So in this change, I have both redirected Output::scalarString to use
yaml::escape _and_ modified yaml::escape to optionally restrict its escaping to
non-printables. This preserves behaviour of any existing clients while giving
them a path to more moderate escaping should they desire.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

- Add AllocatorList, a non-intrusive list that owns an LLVM-style
allocator and provides a std::list-like interface (trivially built on
top of simple_ilist),
- add a typedef (and unit tests) for BumpPtrList, and
- use BumpPtrList for the list of llvm::yaml::Token (i.e., TokenQueueT).
TokenQueueT has no need for the complexity of an intrusive list. The
only reason to inherit from ilist was to customize the allocator.
TokenQueueT was the only example in-tree of using ilist<> in a truly
non-intrusive way.
Moreover, this removes the final use of the non-intrusive
ilist_traits<>::createNode (after r280573, r281177, and r281181). I
have a WIP patch that removes this customization point (and the API that
relies on it) that I plan to commit soon.
Note: AllocatorList owns the allocator, which limits the viable API
(e.g., splicing must be on the same list). For now I've left out
any problematic API. It wouldn't be hard to split AllocatorList into
two layers: an Impl class that calls DerivedT::getAlloc (via CRTP), and
derived classes that handle Allocator ownership/reference/etc semantics;
and then implement splice with appropriate assertions; but TBH we should
probably just customize the std::list allocators at that point.
llvm-svn: 281182
Many lists want to override only allocation semantics, or callbacks for
iplist. Split these up to prevent code duplication.
- Specialize ilist_alloc_traits to change the implementations of
deleteNode() and createNode().
- One common desire is to do nothing deleteNode() and disable
createNode(). Specialize ilist_alloc_traits to inherit from
ilist_noalloc_traits for that behaviour.
- Specialize ilist_callback_traits to use the addNodeToList(),
removeNodeFromList(), and transferNodesFromList() callbacks.
As a drive-by, add some coverage to the callback-related unit tests.

Remove all the dead code around ilist_*sentinel_traits. This is a
follow-up to gutting them as part of r279314 (originally r278974),
staged to prevent broken builds in sub-projects.
Uses were removed from clang in r279457 and lld in r279458.

Share code for the (mostly problematic) embedded sentinel traits.
- Move the LLVM_NO_SANITIZE("object-size") attribute to
ilist_half_embedded_sentinel_traits and ilist_embedded_sentinel_traits
(previously it spread throughout the code duplication).
- Add an ilist_full_embedded_sentinel_traits which has no UB (but has
the downside of storing the complete node).
- Replace all the custom sentinel traits in LLVM with a declaration of
ilist_sentinel_traits that inherits from one of the embedded sentinel
traits classes.
There are still custom sentinel traits in other LLVM subprojects. I'll
remove those in a follow-up.
Nothing at all should be changing here, this is just rearranging code.
Note that the final goal here is to remove the sentinel traits
altogether, settling on the memory layout of
ilist_half_embedded_sentinel_traits without the UB. This intermediate
step moves the logic into ilist.h.

Stop relying on ilist implicit conversions from `value_type&` to
`iterator` in YAMLParser.cpp.
I eventually want to outlaw this entirely. It encourages
`getNextNode()` and `getPrevNode()` in iterator logic, which is
extremely fragile (and relies on them never returning `nullptr`).
FTR, there's nothing nefarious going on in this case, it was just easy
to clean up since the callers really wanted iterators to begin with.

The commit null terminates the string value in the `yaml::BlockScalarNode`
class.
This change is motivated by the initial MIR serialization commit (r237708)
that I reverted in r237730 because the LLVM IR source from the block
scalar node wasn't terminated by a null character and thus the buildbots
failed on one testcase sometimes. This change enables me to recommit
the reverted commit.

The commit r237314 that implements YAML block parsing
introduced a leak that was caught by the ASAN linux buildbot.
YAML Parser stores its tokens in an ilist, and allocates
tokens using a BumpPtrAllocator, but doesn't call the
destructor for the allocated tokens. R237314 added an
std::string field to a Token which leaked as the Token's
destructor wasn't called. This commit fixes this leak
by calling the Token's destructor when a Token is being
removed from an ilist of tokens.

This commit implements the parsing of YAML block scalars.
Some code existed for it before, but it couldn't parse block
scalars.
This commit adds a new yaml node type to represent the block
scalar values.
This commit also deletes the 'spec-09-27' and 'spec-09-28' tests
as they are identical to the test file 'spec-09-26'.
This commit introduces 3 new utility functions to the YAML scanner
class: `skip_s_space`, `advanceWhile` and `consumeLineBreakIfPresent`.

This commit enables the tests located in test/YAMLParser directory.
Those tests were never actually enabled, as llvm-lit didn't pick up the
files with the 'data' extension. The commit renames those test files to files
with the 'test' extension so that llvm-lit would find them.
This commit also modifies yaml-bench so that it returns an error status
if an error occurred during parsing. It also adds the '-use-color'
command line option to yaml-bench (to make sure that file check matches
the error messages in the output stream).
This commit modifies some of the renamed tests so that they wouldn't
fail. It gets rid of XFAILs and uses the 'not' command instead for
some of the tests that have to fail during parsing. This commit
also adds some 'FIXME' comments to a couple of tests that are
supposed to fail but currently pass because of various bugs
in the implementation of the yaml parser.

This commit extracts the code that skips over a YAML comment from
the 'scanToNextToken' method into a separate 'skipComment' method.
This refactoring is motivated by a patch that implements parsing
of YAML block scalars (http://reviews.llvm.org/D9503), as the
method that parses a block scalar reuses the 'skipComment' method.

This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
Base *foo = new Child();
delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.
Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

The rationale is to get YAML filenames in diagnostics from
yaml::Stream::printError -- currently the filename is hard-coded as
"YAML" because there's no buffer information available.
