Oes spec says:
For the both the input array gl_SampleMaskIn[] and the output array gl_SampleMask[], bit B of mask M
(gl_SampleMaskIn[M] or gl_SampleMask[M]) corresponds to sample 32*M+B. These arrays have
ceil(gl_MaxSamples/32) elements, where gl_MaxSamples is the maximum number of color samples
supported by the implementation.
But glslang report error "array must have size before use length".
layout(location = 0) out mediump vec4 fragColor;
void main (void)
{
for (int i = 0; i < gl_SampleMask.length(); ++i)
gl_SampleMask[i] = int(0xAAAAAAAA);
fragColor = vec4(0.0, 1.0, 0.0, 1.0);
}
* Add two test items, one is for gl_MaxSapmles = 32 and the other one is for gl_MaxSapmles = 64.
glslang representing literal constants with double precision, so 1.0e40 and 1.0e-50 are normal values.
Shader1：
precision highp float;
out vec4 my_FragColor;
void main()
{
// Out-of-range floats should overflow to infinity
// GLSL ES 3.00.6 section 4.1.4 Floats:
// "If the value of the floating point number is too large (small) to be stored as a single precision value, it is converted to positive (negative) infinity"
float correct = isinf(1.0e40) ? 1.0 : 0.0;
my_FragColor = vec4(0.0, correct, 0.0, 1.0);
}
The expected ouput result of this test is vec4(0.0, 1.0, 0.0, 1.0),
but it's vec4(0.0,0.0,0.0,1.0).Because the return value of isInf is
false.
precision highp float;
out vec4 my_FragColor;
void main()
{
// GLSL ES 3.00.6 section 4.1.4 Floats:
// "A value with a magnitude too small to be represented as a mantissa and exponent is converted to zero."
// 1.0e-50 is small enough that it can't even be stored as subnormal.
float correct = (1.0e-50 == 0.0) ? 1.0 : 0.0;
my_FragColor = vec4(0.0, correct, 0.0, 1.0);
}
The expected ouput result of this test is vec4(0.0, 1.0, 0.0, 1.0),
but it's vec4(0.0,0.0,0.0,1.0).
For f32 and f16 type, when the literal constant out of range of the f32
and f16 number, the value should overflow or underflow to inf or zero.

For recent GLSL versions, if texture2D function call appears, the error
message reports an unsupported type constructor. Change message to
unsupported function. Likewise for other removed texture* function calls.
Specifically, make GLSL link error messages more specific and output
only information relevant to the error.
Also change type printing to more closely reflect GLSL syntax. This
is the default for link error messages, but must me enabled with the
new option --enhanced-msgs for compilation error messages.
Also with --enhanced-msgs, only emit one error message per source
line.
`glslangValidator` will only return [the codes 0..6](b481744aea/StandAlone/StandAlone.cpp (L117-L125)). Fail the test if anything else is returned (like due to the exe crashing).
Also set `LD_LIBRARY_PATH` to contain the `lib` directory before calling glslang.
* Add Shared/Std140 SSBO process & top-level array elements related
process
1.Add process options for shared/std140 ssbo, following ubo process
2.Add IO Variables reflection option, would keep all input/output
variables in reflection
3.Add Top-level related process, fix top-level array size issues,
following spec
4.Split ssbo/ubo reflection options, merge blowup expanding all into
function blowupActiveAggregate to allow other functions keep same entry
format.
Add options in StandAlone and test symbols.
1. Add options in StandAlone for std140/shared ubo/ssbo and all io variables reflection.
2. Add test for ssbo. When EShReflectionSharedStd140SSBO turns on, generated symbol and output would be different, to remind the difference. Defaultly disabled and nothing would change, nor blocking normal test.
* Add options in runtest script, refresh test results.
Add options in StandAlone:
--reflect-all-io-variables --reflect-shared-std140-ubo --reflect-shared-std140-ssbo
refresh test results.
Now the index, size of unsized array are expected.
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.
Saved about 21K, size down to 380K of MSVC x86 code.
Fixed one bug that needs to be looked at on the master branch:
The test for needing a Vulkan binding has a bug in it, "!layoutAttachment"
which does not mean "no layoutAttachment", because that is non-zero.
This is why some test and test results changed.
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 comes from the resolution of issues 4, 5 & 6 in
ARB_program_interface_query, stating that uniform buffers should have their
members expanded out as normal and arrays should have elements added.
* If a buffer block has a large array e.g. [10000] we don't want to iterate over
every array element. Instead we should only expand out the first [0] element,
then expand as normal from there.
* The array name should still be appended with [0] to indicate that it's an
array.
Adds command line options:
--invert-y
--iy
(synonyms) which invert position.Y on vertex shader output. Handles these cases:
* Direct single variable return
* Member of direct returned struct
* Single variable output parameter
* Member of struct output parameter
API:
// Enables position.Y output negation in vertex shader
void TShader::setInvertY(bool invert);
Fixes#1173
Per feedback on PR #1111, this reverses the order of the parameters for the setShiftBinding API.
It is now:
void TShader::setShiftBindingForSet(TResourceType res, unsigned int base, unsigned int set);
