Get the number of required registers for each basic block.

Creates a select instruction. |type| must match the types of |true_value| and |false_value|. It is up to the caller to ensure that |cond| is a correct

TODO(pierremoreau): If OpDecorateId is referencing an OpConstant, one could check that the constants are the same rather than just looking at the cons

Returns the dependence source for the control dependence for the given id. This only exists for data -> control edges. In other words, if block 2 is

Returns a short textual description of the id defined by the given instruction.

Returns the list of induction variables within the loop.

Get the unique root of the tree. It is guaranteed to work on a dominator tree. post-dominator might have a list.

Returns a pointer to the definition of an unsigned 32-bit integer constant with the given value. Returns |nullptr| if the constant does not exist and

Returns true if this loop contains any nested loops.

Performs |input1| |opcode| |input2| and returns the merged constant result id. Returns 0 if the result is not a valid value. The input types must be I

This is dirty copy of the spirv.hpp11 function TODO - Use a generated version of this function

Returns a pointer to the null-terminated C-style string in the global strings table, as referenced by 'ir'. Assumes the given range is valid.

Gets the SPIR-V version of this module.

Creates a phi instruction. The id |type| must be the id of the phi instruction's type. The vector |incomings| must be a sequence of pairs of <definiti

Returns true if the loop can be peeled. To be peelable, all operation involved in the update of the loop iterators must not dominates the exit conditi

True if the operand of a debug info instruction |inst| at |word_index| satisfies |expectation| that is given as a function. Otherwise, returns false.

Returns true is a function declaration and not a function definition.

Testing method to allow setting the current layout section.

Returns SPIR-V assembly for a shader that uses a given decoration instruction.

Returns all superclasses of a given class. Omits root 'object' superclass. Returns: A list of superclasses of the given class. The order gu

Gets all validation methods. Returns: A list of validation methods. The order guarantees that * A method defined in superclass preced

operand parses the operand with the name n, kind k, starting at the i'th token.

Returns true if the block is reachable in the CFG.

Returns true if and only if every pointer parameter and variable associated with |function_id| in |context| is known by |transformation_context| to be

Collect all the recurrent nodes in this SENode

Checks the given |error_message| is reported when trying to build a module from the given |assembly|.

Returns expected error string if |opcode| produces a duplicate type declaration.

Returns Execution Models for the given Entry Point. Returns nullptr if none found (would trigger assertion).
