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".
* Use `GNUInstallDirs` in order to respect GNU conventions.
This is especially important for multi-arch/multi-lib setups.
* Specify position independent mode building properly, without
using the historic hack of adding `-fPIC` as a definition.
This makes the build system more portable.
* Only detect C++ (and not C) to slightly speed up configuring.
* Specify C++11 mode using modern CMake idioms.
* Fix some whitespace issues.
- Support GL_AMD_shader_ballot (SPV_AMD_shader_ballot).
- Support GL_AMD_shader_trinary_minmax (SPV_AMD_shader_trinary_minmax).
- Support GL_AMD_shader_explicit_vertex_parameter
(SPV_AMD_shader_explicit_vertex_parameter).
- Support GL_AMD_gcn_shader (SPV_AMD_gcn_shader).
This adds solution folders that properly group gtest/glslang/hlsl.
This also marks gtest options as advanced so they don't show up
in cmake-gui by default.
The existing test harness is a homemade shell script. All the tests
and the expected results are written in plain text files. The harness
just reads in a test, invoke the glslangValidator binary on it, and
compare the result with the golden file. All tests are kinda
integration tests.
This patch add Google Test as an external project, which provides a
new harness for reading shader source files, compile to SPIR-V, and
then compare with the expected output.
* Linux folder has been renamed to Unix, to match defines and so that it
compiles on OS X.
* This removes the need for a per-platform include search path for the
right OS folder
