Detailed Description

Conditionally change control flow.

Enumeration Type Documentation

A type to express conditional jump predictions.

Enumerator:
COND_JMP_PRED_NONE 

No jump prediction.

Default.

COND_JMP_PRED_TRUE 

The True case is predicted.

COND_JMP_PRED_FALSE 

The False case is predicted.

Definition at line 237 of file firm_types.h.

enum n_Cond

Input numbers for Cond node.

Definition at line 1050 of file nodeops.h.

enum pn_Cond

Projection numbers for result of Cond node (use for Proj nodes)

Enumerator:
pn_Cond_false 

control flow if operand is "false"

pn_Cond_true 

control flow if operand is "true"

Definition at line 1059 of file nodeops.h.
