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.
Previously GlslangToSpv() reported missing/TBD functionalities
by directly writing to stdout using printf. That could cause
problems to callers of GlslangToSpv(). This patch cleans up
the error reporting logic in GlslangToSpv(), TGlslangToSpvTraverser,
and spv::Builder a little bit to use ostringstream.
Also fixed the usage of GlslangToSpv() in GTest fixtures to
capture warnings/errors reported when translating AST to SPIR-V.
Note this requires test-based piecing together of the preamble string,
so it changed to being a std::string to make it easier to do.
This closes issue #254.
This is a replacement commit for pull request #238.
This is a design change, followed by implementation change that
A) fixes the changes caused by the design change, and
B) fixes some cases that were originally incorrect.
The design change is to not give built-in functions default precision qualification.
This is to allow the rule that the precision of some built-in functions adopt their
precision qualification from the calling arguments. This is A above.
A consequence of this design change is that all built-ins that are supposed to have
an explicit precision qualifier must now be declared that way. So, a lot more
built-in declarations now have precision qualifiers, just to keep things the same.
This is B above.
- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.
Some license information were missing for some of the files, I have
added the proper licensing information as well as author information
for both files.
The input scanner can be trapped in an infinite loop if the given input
file does not have EOF (and is not ended with a 'whitespace').
The problem is caused by unget(), which keeps rolling back the scanner
pointer without hitting an EOF at the end of the file. This makes getch()
function keep returning the last character of the file and never ends,
and the effect of advance() is always counteracted by unget().
Fix issue: #237
1. The code generated for matrix constructor should 1) build column
vectors first, 2) build matrix with the vectors.
2. When there is only one scalar type constituent in vector's
constructor, we should populate the constituent to fill all the slots in
the vector. As for matrix, the single constituent should be populated to
the diagonal positions (top-left to bottom-right diagonal).
remove createSpvConstantFromConstSubTree()
Bool -> uint/int with OpSpecConstantOp OpSelect instruction.
uint <-> int conversion with OpSpecConstantOp OpIAdd instruction.
Note, implicit conversion: `const uint = an_int_spec_constant` is not
supported. Explicit type casting is required: `const uint =
uint(an_int_spec_constant)`
