Compare 2 fractions while first normalizing them, e.g. 2/4 and 4/8 will both be simplified to 1/2 and then determined to be equal.

Returns a folding rule that folds the instruction to operand |foldToArg| (0 or 1) if operand |arg| (0 or 1) is a zero constant.

Log is invoked for all messages flowing through a Conn. direction indicates if the message being received or sent id is the message id, if not set it

Assembles the given |shader| text, and then: - Runs the fuzzer with |seed| to yield a set of transformations - Shrinks the transformation with various

Sets the pointer to the current context for this pass.

Sets the message consumer to the given |consumer|. |consumer| which will be invoked every time there is a message to be communicated to the outside.

Sets up a Reducer for use in the CheckValidationOptions test; avoids repetition.

Calling Stop() does nothing but just increases |count_stop_| by 1.

String returns a string representation of the ID. The representation is non ambiguous, string forms are quoted, number forms are preceded by a #

A helper function to strip OpName instructions from the given string of disassembly code and put those debug instructions to a set. Returns the string

Traces the variable pointer inst backwards. checker is called on each visited instruction.

Wrote is called each time some data is written to the stream.

Aligns the specified value to a multiple of alignment, whereas the alignment must be a power-of-two.

Iterators over the immediate sub-loops.

Iterate over immediate child nodes.

Returns true if all ids of given type have a specified decoration.

Runs a command in a directory and returns its standard output stream. Returns (False, None) if the command fails to launch or otherwise fails.

Returns a set with ids of all functions called from this function.

Returns scalar alignment of a type.

Returns size of a struct member. Doesn't include padding at the end of struct or array. Assumes that in the struct case, all members have offsets.

Fetches the next word from the given text stream starting from the given position. On success, writes the decoded word into *word and updates position

Returns a pointer to a liveness manager. If the liveness manager is invalid, it is rebuilt first.

Iterate over all child nodes in the graph.

Returns true if the given ID has the Import LinkageAttributes decoration.

newline returns true if the i'th token is a Newline, otherwise false.

offset is a copy of the Offset function in go/token, but with the adjustment that it does not panic on invalid positions.

Returns the addressing model of this module, or Logical if uninitialized.

Returns true if the characters in the text as position represent the start of an Opcode.

string processes the String token at the current position. The lexer *must* know the next token is a String before calling.

Returns a list of SPIR-V assembly strings, where each uses only types and IDs that can fit with a shader made from parts from the result of ShaderPart
