Enumeration Type Documentation

cond_jmp_predicate

enum cond_jmp_predicate

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 212 of file firm_types.h.

n_Cond

enum n_Cond

Input numbers for Cond node.

Enumerator
n_Cond_selector	condition parameter
n_Cond_max

Definition at line 1197 of file nodes.h.

pn_Cond

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"
pn_Cond_max

Definition at line 1205 of file nodes.h.
