Member Data Documentation

◆ InOrder

MachineInstr* llvm::VOPDMatchInfo::InOrder[2]

The component instructions in program order.

Definition at line 46 of file GCNVOPDUtils.h.

Referenced by getMIX(), and getMIY().

◆ IsVOPD3

bool llvm::VOPDMatchInfo::IsVOPD3

Definition at line 49 of file GCNVOPDUtils.h.

◆ LiteralFixups

SmallVector<VOPDLiteralFixup, 2> llvm::VOPDMatchInfo::LiteralFixups

Immediates which have to be moved into scalar registers before the pair can be built.

They all have the same 32-bit value, so one register serves the whole pair. Only a VOPD3 pair can need this.

Definition at line 53 of file GCNVOPDUtils.h.

◆ XIdx

unsigned llvm::VOPDMatchInfo::XIdx

Which entry in InOrder is the X component.

Definition at line 48 of file GCNVOPDUtils.h.
