llvm::MCReadAdvanceEntry Struct Reference

#include <MCSchedule.h>

Collaboration diagram for llvm::MCReadAdvanceEntry:

Public Member Functions
bool	operator== (const MCReadAdvanceEntry &Other) const

Public Attributes
unsigned	UseIdx
unsigned	WriteResourceID
int	Cycles

Detailed Description

Specify the number of cycles allowed after instruction issue before a particular use operand reads its registers. This effectively reduces the write's latency. Here we allow negative cycles for corner cases where latency increases. This rule only applies when the entry's WriteResource matches the write's WriteResource.

MCReadAdvanceEntries are sorted first by operand index (UseIdx), then by WriteResourceIdx.
