Function Documentation

void irg_assert_verify

(

ir_graph *

irg

)

Convenience function: Checks graph for errors, in case of error the graph is dumped to a file with "-assert" suffix and the program aborted.

int irg_verify

(

ir_graph *

irg

)

Calls irn_verify() for each node in irg.

Also checks some global properties like all (non-phi) operands dominating their points of usage; Also checks if the control flow parts of a graph are valid.

Parameters

irg	the IR-graph to check

Returns

NON-zero if no problems were found

int irn_verify

(

const ir_node *

node

)

Tests node for well-formedness.

This mostly tests modes of inputs/outputs. Only local properties are tested global properties are only checked by irg_verify().

Returns

NON-zero if no problems were found
