canDiscardReachingOutDefinition

boolean canDiscardReachingOutDefinition(IERoutineContext ectx,
 long insnAddress,
 int def)

Check if an unused variable definition, bleeding out from the routine, may be safely discarded.

The implementation may depend on the master optimizer's mode.

Parameters:

ectx -

insnAddress - instruction address

def - defined, unused variable

Returns:

canDiscardUnusedDefinition

boolean canDiscardUnusedDefinition(IERoutineContext ectx,
 long insnAddress,
 int def)

Check if an unused variable definition, not bleeding out from the routine, may be safely discarded.

The implementation may depend on the master optimizer's mode.

Parameters:

ectx -

insnAddress - instruction address

def - defined, unused variable

Returns:
