// This implements a simple VLIW packetizer using DFA. The packetizer works on
|
|
|
|
// machine basic blocks. For each instruction I in BB, the packetizer consults
|
|
|
|
// the DFA to see if machine resources are available to execute I. If so, the
|
|
|
|
// packetizer checks if I depends on any instruction J in the current packet.
|
|
|
|
// If no dependency is found, I is added to current packet and machine resource
|
|
|
|
// is marked as taken. If any dependency is found, a target API call is made to
|
|
|
|
// prune the dependence.
