GitHub releases were just the exact same as the LunarG releases,
since the same commit were used for both.
For this reason, we don't think it brings any value, and will stop
publishing new releases on the GitHub page.

Before, we did set cxx version to c++17 using COPTS in our bazel files.
This was wrong, and part of the dependencies were then built with the
default standard version. This was not an issue until we moved to c++17.
Then, we decided to use the bazel --cxxopt=-std=c++17, but this was only
valid for nix platforms.
The last option left is to ask the user to specify the standard
when building using bazel.
* build: move from c++11 to c++17
Moving from cpp 11 to cpp 17 will allow us to use modern features like
filesystem support, optional, any, execution policies and improved
templates.

* Use bazel 5 for Linux bazel builds.
* Download bazel 5.0.0 for macos and windows bazel builds.
* Modify the readme to mention bazel 5.0.0 as the version to use.
spirv-diff is a new tool that produces diff-style output comparing two
SPIR-V modules. The instructions between the src and dst modules are
matched as best as the tool can, and output is produced (in src
id-space) that shows which instructions are removed in src, added in dst
or modified between them. The order of instructions are not retained.
Matching instructions between two SPIR-V modules is not trivial, and
thus a number of heuristics are applied in this tool. In particular,
without debug information, it's hard to match functions as they can be
reordered. As such, this tool is primarily useful to produce the diff
of two SPIR-V modules derived from the same source.
This tool can be useful in a number of scenarios:
- Compare the SPIR-V before and after modifying a shader
- Compare the SPIR-V produced from a shader before and after compiler
codegen changes.
- Compare the SPIR-V produced from a shader before and after some
transformation or optimization.
- Compare the SPIR-V produced from a shader with different compilers.
- Mention that `depot_tools` are required and link to that repo.
- Make `roll_deps.sh` exit on error. The script passes `shellcheck`
with this change.
- Reword instruction in the README.
- Remove Appveyor CI
- Write new "Getting the source" subsection, consolidating material
from a couple of places. Emphasize using the utils/git-sync-deps
script for getting a known-good combination of sources.
- Built artifacts:
- top of tree artifacts are from Kokoro CI bots
- mention Vulkan SDK and Android NDK as alternatives

This change improves spirv-fuzz CMake code to be more compatible with other projects that might want to include spirv-fuzz as a sub-project.
* Add a CMake option for building spirv-fuzz.
* We now check if protobuf targets are already available.
* We no longer specify `-DGOOGLE_PROTOBUF_NO_RTTI -DGOOGLE_PROTOBUF_USE_UNALIGNED=0`; a newer version of protobuf does not require this. Note that we probably should have specified this for protobuf targets as well, but this is no longer needed.
* Updated protobuf version in Kokoro scripts and README.md.
This adds in a script for updating DEPS and another for pulling in the
specified versions in the DEPS file.
DEPS entries that are not part of the documented build processs are
removed. Using the documented cmake process with them made for a very
sad state of one's checkout. If this removal breaks workflows we can
revist this, since the state is saved in git.
DEPS are rolled forward, so that this is taking use to a known good
state. These look like scary big rolls, but in reality the bots and
most people are running near HEAD for external/, so this integration
should already have been tested.
Summary of DEPS roll:
+ Rolling 3 dependencies
+ Roll external/effcee/ 04b624799..b83b58d17 (14 commits)
+ Roll external/googletest/ 98a0d007d..2f42d769a (576 commits)
+ Roll external/re2/ 6cf8ccd82..848dfb7e1 (90 commits)
+ Created with:
+ roll-dep external/effcee external/googletest external/re2 external/spirv-headers
Fixes#2665
Updated script to work with python3 and python2.
Added required tools.
We added a section to the readme to mention the tools that are needed to
build and test spirv-tools. For the compiler, the compilers used by the
bots are mentioned.
The bots have been changed. The windows bots will not use python 3.6 for testing. The other bots will still use python 2.7. Both Python2 and Python3 will be tested.
Fixes#2407.
Fixes#1856.
There was some confusion about the SPIRV_WERROR option when it is turned
off. When the option is off nothing is done. That is, we do not add
-Wno-error. This means that if the parent project added -Werorr to the
C flags or CXX flags, then warnings will still be treated as errors.
I've updated the README.md to make this explicit.
Fixes#2121.
