Member Data Documentation

◆ Commute

bool llvm::VOPDMatchInfo::Commute[2] = {false, false}

Entries in InOrder which only pair once commuted.

The match was checked with them commuted, but they are left unchanged until the pair is built.

Definition at line 56 of file GCNVOPDUtils.h.

◆ 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.
