Function Documentation

cloneCandidateFunction()

Function * cloneCandidateFunction ( Function * F, unsigned NSpecs )

static

Clone the function F and remove the ssa_copy intrinsics added by the SCCPSolver in the cloned version.

Definition at line 831 of file FunctionSpecialization.cpp.

getCostValue()

unsigned getCostValue ( const Cost & C )

static

Get the unsigned Value of given Cost object.

Assumes the Cost is always non-negative, which is true for both TCK_CodeSize and TCK_Latency, and always Valid.
