1. Sink adding noContraction decoration to createBinaryOperation() and
createUnaryOperation().
2. Fix comments.
3. Remove the #define of my delimiter, use global constant char.
Reimplement the whole workflow to make that: precise'ness of struct
members won't spread to other non-precise members of the same struct
instance.
Approach:
1. Build the map from symbols to their defining nodes. And for each
object node (StructIndex, DirectIndex, Symbol nodes, etc), generates an
accesschain path. Different AST nodes that indicating a same object
should have the same accesschain path.
2. Along the building phase in step 1, collect the initial set of
'precise' (AST qualifier: 'noContraction') objects' accesschain paths.
3. Start with the initial set of 'precise' accesschain paths, use it as
a worklist, do as the following steps until the worklist is empty:
1) Pop an accesschain path from worklist.
2) Get the symbol part from the accesschain path.
3) Find the defining nodes of that symbol.
4) For each defining node, check whether it is defining a 'precise'
object, or its assignee has nested 'precise' object. Get the
incremental path from assignee to its nested 'precise' object (if
any).
5) Traverse the right side of the defining node, obtain the
accesschain paths of the corresponding involved 'precise' objects.
Update the worklist with those new objects' accesschain paths.
Label involved operations with 'noContraction'.
In each step, whenever we find the parent object of an nested object is
'precise' (has 'noContraction' qualifier), we let the nested object
inherit the 'precise'ness from its parent object.
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.
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.
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().
This is according to the expected KHR_vulkan_glsl without floating point.
So, floating-point spec-const operations no longer work, and that's
reflected in the tests.
This plumbs both the current file path and the include depth
back up to the includer. This allows the includer to properly
support relative paths.
This also replaces the string copy that was done during include
with a zero-copy method of accomplishing the same thing. This
prevents extra copies of entire files.
Much about const or temp is mechanical, about actual declaration,
while much is semantic, about something higher level. This commit
checks every use everywhere, and for the high-level ones, substitutes
an encapsulated version instead.
Adds parseVersions.h as the base TParseVersions for versioning,
and splits the remainder between TParseContextBase (sharable across parsers)
and TParseContext (now the GLSL-specific part).
