struct MCWriteLatencyEntry

Declaration

struct MCWriteLatencyEntry { /* full declaration omitted */ };

Description

Specify the latency in cpu cycles for a particular scheduling class and def index. -1 indicates an invalid latency. Heuristics would typically consider an instruction with invalid latency to have infinite latency. Also identify the WriteResources of this def. When the operand expands to a sequence of writes, this ID is the last write in the sequence.
