Returns the block's merge instruction, if one exists (otherwise null).

Returns the signficand after it has been normalized.

for mapping a storage block index to the storage block's description

Lookup or calculate the offset of a block member, using the recursively defined block offset rules.

for mapping any name to its index (only pipe input/output names)

Get code that is not part of a shared symbol table, is specific to this shader, or needed by the preprocessor (which does not use a shared symbol tabl

Checks the preciseness of a given assignment node with a precise object represented as access chain. The precise object shares the same symbol with th

A helper function to get the unsigned int from a given constant union node. Note the node should only hold a uint scalar.

A helper function to get the access chain after removing a given prefix.

Traverses the AST and returns a tuple of four members: 1) a mapping from symbol IDs to the definition nodes (aka. assignment nodes) of these symbols.

Returns the bits associated with the value, without the leading sign bit.

Some simple source assignments need to be flattened to a sequence of AST assignments. Catch these and flatten, otherwise, pass through to intermediate
