Returns true if the opcode leads to an assignment operation.

A helper function to tell whether a node is 'noContraction'. Returns true if the node has 'noContraction' qualifier, otherwise false.

Both test and if necessary, spit out an error, to see if the node is really an l-value that can be operated on this way. Returns true if there was an

Given a function name, find its subroot in the tree, and push it onto the stack of functions left to process.

Update the given type with any type-like attribute information in the attributes.

go back one character

Parse and add to the given symbol table the content of the given shader string.

Return true for the end of a single argument key, which can be the end of the string, or the comma separator.

Map from profile enum to externally readable text name.

Translate glslang type to SPIR-V memory decorations.

Map I/O variables to provided offsets, and make bindings for unbound but live variables. Returns false if the input is too malformed to do this.

Low level: add unary node (no promotions or other argument modifications)

Do size checking for an array type's size.

Within a set of profiles, see if a feature is deprecated and give an error or warning based on whether a future compatibility context is being use.

Recursively checks if the type contains a built-in variable

Return the size and alignment of a component of the given type. The size is returned in the 'size' parameter Return value is the alignment..

extract strings out of attribute arguments stored in attribute aggregate. convert to lower case if converToLower is true (for case-insensitive compare

Because the test node can be a declaration in a while loop, this function unwraps it to get the actual expression.

Read the next token from a macro token stream.

Returns true if the operation is an arithmetic operation and valid for the 'NoContraction' decoration.
