There were two implementations of isInf() and isNan(), in Constant.cpp
and in intermOut.cpp. The former only works on little-endian systems,
the latter is a wrapper for library functions and works regardless of
endianness. Move the second version into Common.h and adopt it in both
places. Thereby avoid the duplication and fix for big-endian systems.
A previous commit with the same intent and purpose had missed a required
header for builds on Windows.
On s390x, this fixes the test case
Glsl/CompileToAstTest.FromFile/constFold_frag.
Fixes#2802

Translate printf() to what GL_EXT_debug_printf has done. HLSL could
define non-constant string variable and we don't have such features
in SPIR-V, so just support constant string variable.
We need separate concepts for
- total set of extensions ever enabled, for the back end
- current state of extensions, for parsing
- the set of features currently enabled for building the AST
This change strips a few features similar to GLSLANG_WEB but doesn't
remove every detail like the latter. It also hardcodes profile/version
to core/450.
In particular, TBuiltIns::initialize is specialized to remove most of
what is not supported or won't be supported by ANGLE. The result of
this function is parsed with TParseContext::parseShaderStrings which is
a performance bottleneck.
This change shaves about 300KB off of ANGLE's binary size and reduces
the cost of SetupBuiltinSymbolTable to nearly a sixth.

The changes to glslang/glslang/MachineIndependent/ParseHelper.cpp exist
purely to prevent even more instances of "warning: enumeration value
‘EOp...’ not handled in switch"
v2: Remove 8-bit types. Overzealous copy-and-paste led to adding
support for a bunch of types that the extension doesn't actually enable.
v3: Update expected test results file. Just changing an expected
results file to make a test pass seems sketchy to me, but I'm not sure
what else to do.
v4: Add missing entry for EOpAbsDifference in
TOutputTraverser::visitBinary. Noticed by JohnK.
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.
Closes#1735
GlslangToSpv.cpp
- minor formatting cleanup
BaseTypes.h
- minor formatting cleanup
- add subgroup builtins to GetBuiltInVariableString
(was resulting in "unknown built-in variable" messages in test output)
Initialize.cpp
- better naming and re-use of strings for subgroup builtin variable declarations
- define subgroup builtin variables in ray-tracing shaders
intermOut.cpp
- add handling of the EOpSubgroupParition* variables
(was resulting in "ERROR: Bad aggregation op" messages in test output)
Update test results.
- Adds a pragma to see binary output of double values (not portable)
- Print decimals that show more values, but in a portable way
(lots of portability issues)
- Expand the tests to test more double values
Note: it is quite difficult to have 100% portable tests for floating point.
The current situation works by not printing full precision, and working around
several portability issues.
Add support for Subpass Input proposal of issue #1069.
Subpass input types are given as:
layout(input_attachment_index = 1) SubpassInput<float4> subpass_f;
layout(input_attachment_index = 2) SubpassInput<int4> subpass_i;
layout(input_attachment_index = 3) SubpassInput<uint4> subpass_u;
layout(input_attachment_index = 1) SubpassInputMS<float4> subpass_ms_f;
layout(input_attachment_index = 2) SubpassInputMS<int4> subpass_ms_i;
layout(input_attachment_index = 3) SubpassInputMS<uint4> subpass_ms_u;
The input attachment may also be specified using attribute syntax:
[[vk::input_attachment_index(7)]] SubpassInput subpass_2;
The template type may be a shorter-than-vec4 vector, but currently user
structs are not supported. (An unimplemented error will be issued).
The load operations are methods on objects of the above type:
float4 result = subpass_f.SubpassLoad();
int4 result = subpass_i.SubpassLoad();
uint4 result = subpass_u.SubpassLoad();
float4 result = subpass_ms_f.SubpassLoad(samp);
int4 result = subpass_ms_i.SubpassLoad(samp);
uint4 result = subpass_ms_u.SubpassLoad(samp);
Additionally, the AST printer could not print EOpSubpass* nodes. Now it can.
Fixes#1069
