Add missing `.cfg` files for GN presubmit.
Add missing `recursedeps` in the `DEPS` file.
Call `./update_glslang_sources.py` before attempting to build.
Add more GN spew to the `.gitignore` file.
This CL updates the build scripts to only install to glslang/SPIRV
instead of also installing to the SPIRV/ folder. The deprecation notice
is also removed.
Note, this may cause downstream build issues if include directories have
not been updated
Fixes#1964#2216
This should enable glslang to be used as a dependency of other projects
that target WebAssembly, instead of assuming "EMSCRIPTEN" => "Want
glslang.js".
Allows building non-min-size builds with Emscripten.
Adds ENABLE_GLSLANG_WEB_DEVEL.
Moves the glslang.js files to OSDependent/Web.
Small cleanups and docs update.
You may need to install python 3.x and also
[windows users] may need to get it in your path in front of python 2.7.x.
If you don't need the external projects (i.e., SPIRV-Tools) and don't want
to upgrade to python 3, don't create the External subdirectory and CMake
won't require python 3. (CMake has a bug that makes it find the wrong one
on a first pass if the top level does not require the version needed by
lower levels.)
- Mention that the instructions are written for Bash.
- Quote the CMAKE_INSTALL_PREFIX to handle spaces in $(pwd).
- Remove SSH clone instructions. Instructions on how to clone are for
those unfamiliar with GitHub, so fewer options are better and SSH
requires additional configuration to make work.
- Replace ninja with make, because more people are familiar with it and
we probably don't need to explain how to install it. Fixes#956.
- Remove the section mentioning cygwin, as it's unclear and doesn't
seem necessary.
- Mention minimum language version in the Dependencies section.
- Move `cd $BUILD_DIR` out of the Linux configuration section because
it's needed on both platforms. Add a line about creating the build
directory, too.
Also added known-good mechanism to fetch latest validated spirv-tools.
Also added -Od and -Os to disable optimizer and optimize for size.
Fetching spirv-tools is optional for both glsl and hlsl. Legalization
of hlsl is done by default if spirv-opt is present at cmake time.
Optimization for glsl is currently done through the option -Os.
Legalization testing is currently only done on four existing shaders.
A separate baseLegalResults directory holds those results. All previous
testing is done with the optimizer disabled.
