Jon Leech dd9919749a Change log for August 13, 2018 Vulkan 1.1.83 spec update:
* Update release number to 83.

Public Issues:

  * Use [%inline] directive for all SVGs to reduce file size (public pull
    request 734).
  * Convert XML `value` aliases into \<alias> tags (public pull request
    747).
  * Fix metadoc script showing non-selected extensions (public pull request
    748).
  * Reapply public pull request 742 to make
    ename:VK_PIPELINE_STAGE_CONDITIONAL_RENDERING_BIT_EXT part of the
    graphices pipeline (public pull request 749).
  * Fix numerous typos related to accidental duplication of words (public
    pull request 760).
  * Fix `vk.xml` contact typos (public pull request 761).

Internal Issues:

  * Add images to the <<Standard sample locations>> table (internal issue
    1115).
  * Add a definition of "`Inherited from`" precision in the
    <<spirvenv-precision-operation, Precision and Operation of SPIR-V
    Instructions>> section (internal issue 1314).
  * Clarify that both built-in and user-defined variables count against the
    location limits for shader interfaces in the
    <<interfaces-iointerfaces-locations, Location Assignment>> section
    (internal issue 1316).
  * Merge "`required`" capabilities into the <<spirvenv-capabilities-table,
    list of optional: SPIR-V capabilities>> (internal issue 1320).
  * Relax the layout matching rules of descriptors referring to only a
    single aspect of a depth/stencil image, by reference to the new
    <<resources-image-layouts-matching-rule, Image Layout Matching Rules>>
    section (internal issue 1346).
  * Revert extension metadoc generator warning about name mismatches to a
    diagnostic, due to annoying warnings in build output for conscious
    choices we've made (internal issue 1351).

Other Issues:

  * Reserve bits for pending vendor extensions.
  * Make Vulkan consistent with SPIR-V regarding code:DepthReplacing and
    code:FragDepth in the <<interfaces-builtin-variables, Built-In
    Variables>> section.
  * Add missing ChangeLog entries for the previous three spec updates.

README.adoc

= Vulkan^(R)^ API Documentation Project

This repository contains formal documentation of the Vulkan API. This
includes the Specification of the Vulkan API, including extensions; the
reference ("`man`") pages; the XML API Registry; header files; and related
tools and scripts.

The authoritative public repository is located at
https://github.com/KhronosGroup/Vulkan-Docs/ . Issues, proposed fixes for
issues, and other suggested changes should be created using Github.


== Branch Structure

With the release of Vulkan 1.1, the current Specification is now maintained
in the `master` branch of the repository. It is possible to generate both
Vulkan 1.1 and Vulkan 1.0 Specifications from this branch.


=== `1.0` Branch Is Obsolete

The `1.0` branch in which the 1.0 Specification was previously maintained is
now obsolete. The `1.0` branch will not be updated going forward, and all
outstanding pull requests or merge requests against the `1.0` branch must be
rebased on, and retargeted to `master`.


== Directory Structure

The directory structure was changed following the 1.1.70 spec update to move
the specification directory to the root of the repository, and move other
content relative to that. There may be additional cleanup and simplification
in the future.

== Building the Specification and Reference Pages

The document sources are marked up in `asciidoctor` format, and we use
asciidoctor and related toolchain components to generate output documents.
See `BUILD.adoc` for more information on installing the toolchain and
building the Specification.


== Generating Headers and Related Files

The header files (`include/vulkan/vulkan*.h`) and many parts of the
specification and reference page documents are generated from descriptions
in the XML API Registry (`xml/vk.xml`). The generated files, with the
exception of header files, are not checked into the repository. If you
change `vk.xml`, you can regenerate the header by going to `xml/` and
running:

    $ make clean install

The other generated files are built as required via dependencies in
the top-level `Makefile`.
