This introduces parallel types for IO-type containing aggregates used as
non-entry point function parameters or return types, or declared as variables.
Further uses of the same original type will share the same sanitized deep
structure.
This is intended to be used with the wrap-entry-point branch.
Previously, a type graph would turn into a type tree. That is,
a deep node that is shared would have multiple copies made.
This is important when creating IO and non-IO versions of deep types.
This needs some render testing, but is destined to be part of master.
This also leads to a variety of other simplifications.
- IO are global symbols, so only need one list of linkage nodes (deferred)
- no longer need parse-context-wide 'inEntryPoint' state, entry-point is localized
- several parts of splitting/flattening are now localized
Makes it easier to include glslang in a larger CMake project---instead
of having to call `target_link_libraries(glslang OSDependent OGLCompiler
HLSL)`, for example, you only need to call
`target_link_libraries(glslang)` and it will pull in the helpers it
needs.
This is also better in terms of cleaning up the "public interface",
of sorts, for building glslang: end-users probably shouldn't need to
know or be explicitly dependent on internal targets.
When copying split types with mixtures of user variables and buitins,
where the builtins are extracted, there is a parallel structures traversal.
The traversal was not obtaining the derefenced types in the array case.
- Add support for invocation functions with "InclusiveScan" and
"ExclusiveScan" modes.
- Add support for invocation functions taking int64/uint64/doube/float16
as inout data types.
doc.cpp: Add capabilities, scope to the opcodes. Add opcode and
capability strings.
GLSL.ext.KHR.h: Add extension
string.
GlslangToSpv.cpp: Fix handling of opcodes to generate
appropriate SPIR-V.
spirv.hpp: Add capability and opcode
enums.
spv.shaderGroupVote.comp.out: Update SPIR-V output for test
shader.
Since EOpMatrixSwizzle is a new op, existing back-ends only work when the
front end first decomposes it to other operations. So far, this is only
being done for simple assignment into matrix swizzles.
This partially addressess issue #670, for when the matrix swizzle
degenerates to a component or column: m[c], m[c][r] (where HLSL
swaps rows and columns for user's view).
An error message is given for the arbitrary cases not covered.
These cases will work for arbitrary use of l-values.
Future work will handle more arbitrary swizzles, which might
not work as arbitrary l-values.
This encapsulates where the string could overflow, removing 40 lines
of fragile code. It also improves handling of numbers that are too long.
There are a couple of open issues that could related to this function
being more rational (locale dependence, 1.#INF).
