b9197c812e Web: Make switched methods all be non-virtual, more web-dependent code, 
added a few more HLSL flag tests.  This was mostly focused on the SPV generator.
Saves about 17K.

d8834df992 Web: Optional error management and error tightening.

fb4f2333da Web: Use isEsProfile() instead of run-time testing; remove more atomics 
Saves 2.5K, and design is better.

155d351f86 Web: Remove unused stage functionality, SPIR-V logger, and hex_utils 
Saves another 20K.

39697cdb9d Web: Remove unnecessary GLSL numeric types, and some collateral. 
This saves another 40K of x86 binary, which is about 13% of the target size.

3e4b6ff76a Web: Tighten up sampling code and interfaces.

441b2ac4d1 Web: Prune grammar and lexor down to needed subset. 
About 60K smaller (20% the target size is these units of 300K).
Over 300 fewer #ifdef.

This adds a new glslang.m4 file that needs to be processed by m4 to get
the glslang.y file needed by bison.  See comment in glslang.m4 for more
detail.

This updates the updateGrammar script to do the .m4 -> .y processing,
to conditionally exclude grammar not needed for the web build.

a28f7a75d1 Web: Generalize _EXTENSIONS* in SPIR-V back-end. 
About 50 fewer #ifdefs.
About 14K smaller.
Note, the base size is ill-defined due to optimizer settings (size vs. performance),
compression, and target architecture.  Some recent %'s are accidentally reported as
3X the real savings.  Early %'s were accurate.  What matters though is that each
step got worthwhile gains, and what the final size ends up being.

b6d3ee5aca Web: Turn off bracket-style attributes, reflection, and IO mapping. 2019-08-20 23:21:55 -06:00

7015bd658e Web: Remove/rationalize a set of *_EXTENSIONS, using GLSLANG_WEB. 
Focus was on the front end (not SPIR-V), minus the grammar.
Reduces #ifdef count by around 320 and makes the web build 270K smaller,
which is about 90% the  target size.

The grammar and scanner will be another step, as will the SPIR-V backend.
This makes heavy use of methods #ifdef'd to return false as a global way
of turning off code, relying on C++ DCE to do the rest.

e66dace97e Web: First pass of tabling the built-in function declarations. 
Doing this much saved about 11.5K, including adding all the infrastructure.

23d27751e8 Web: Selectively remove a few key features, using #ifndef GLSLANG_WEB 
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.

bfc21ff1a9 Web: Change a bunch of HLSL methods from dynamic to compile-time known. 
This saves about 7K.
By changing just a few methods to be compile-time known, a bunch of
scattered code becomes DCE.

d4ed5158d1 Web: Remove a few additional HLSL constructs with ENABLE_HLSL.

not okay when the array size is an expression.

dbe6b06dde Add missing GL_ARB_shader_ballot builtins to Geometry and Tessellation shaders 
When processing Geometry and Tessellation Control/Evaluation shaders,
the builtins defined by GL_ARB_shader_ballot were not processed by
glslang. This specially a problem for gl_SubGroupSizeARB because, it is
treated as shader input instead of uniform on Vulkan.
