This should enable glslang to be used as a dependency of other projects
that target WebAssembly, instead of assuming "EMSCRIPTEN" => "Want
glslang.js".
This CL allows setting the location of glslangValidator and spirv-remap
when calling the runtests script. A test target is added to CMake to
execute runtests and sets the location to the build folder for the two
applications.
This reverts commit 41261d95a4.
This reverts commit 7c9accb653.
Instead of trying to work around all of the potential semicolon issues
in glslang, making it conform to Chromium's style, mark the code
explicitly as non-chromium in the BUILD.gn, so chromium doesn't
attempt to enforce its style rules on glslang.
Fixes#1931
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.
Save about 100K.
N.B.: This is done by eliminating a function call, at a high level,
not by #ifdef'ing a bunch of code.
Also, removed no longer needed *_EXTENSION #ifdef in the code not
needed by GLSLANG_WEB.
This adds build rules to support generating a WASM binary to be used
on the web. The API exposed to web applications is definated in the
new glslang.js.cpp file.
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.)
For nested project builds, writing CMAKE_DEBUG_POSTFIX into the cache
ends up affecting other projects. Caching this value doesn't seem to be
required in practice, so this change removes the cache tag.
This is totally optional, but lets people build this repo with
ccache to improve rebuild speeds. It also can help a great deal
on ccache-enabled CI systems like Travis-CI. We build fixed
revisions of glslang a lot on Travis, so this will be a big help
with CI machine loading.
Remapper errors are generally fatal: there has been some unexpected situation while
parsing the SPV binary, and there is no reasonable way to carry on. The
errorHandler() function is called in this case, which by default exits, but
it is possible to submit a handler which does not. In that case the remapper would
carry on in a bad state.
This change ensures a graceful termination of the remap() function.
While a try {} catch {} construct would be the ideal and safe way to do this,
that's off limits for certain environments, so this tries to do the same thing
with explicit code, to catch all the bailout paths.
As a static target, when included in other cmake projects, it is not needed to install these libraries and headers as part of this build, and just need to link to this.
This reverts commit cfc69d95af.
* Change CMAKE_INSTALL_PREFIX default on Windows in order
to prevent permission denied errors when trying to install
to "Program Files".
