Compare two SlotIndex objects for equality.

Comparisons between register objects

Comparison operator.

Comparison operator.

Compare two SlotIndex objects. Return true if the first index is greater than the second.

Sort the node sets by importance. First, rank them by recurrence MII, then by mobility (least mobile done first), and finally by depth. Each node set

Check if this is greater than \p Cost.

Compare two SlotIndex objects. Return true if the first index is greater than, or equal to, the second.

Specially implement the [] operation using a proxy object to support assignment.

Same as getLoopFor.

handler for bit test and branch instruction. Used by M6805. The bit index is part of the opcode. Example: BRSET 3,<$40,LOOP

See if the comparison instruction can be converted into something more efficient. E.g., on ARM most instructions can set the flags register, obviating

Try to remove the load by folding it to a register operand at the use. We fold the load instructions if and only if the def and use are in the same BB

Given a select instruction that was understood by analyzeSelect and returned Optimizable = true, attempt to optimize MI by merging it with one of its

Order the symbols in the local stack frame. The list of objects that we want to order is in \p objectsToAllocate as indices into the MachineFrameInfo.

overlaps - Return true if the intersection of the two live ranges is not empty.

Returns true if the specified SDep is equivalent except for latency.

Override generic scheduling policy within a region. This is a convenient way for targets that don't provide any custom scheduling heuristics (no cust

The following APIs encodes/decodes per-probe information to/from a 32-bit integer which is organized as: [2:0] - 0x7, this is reserved for regular dis

Implement target specific parsing of target custom pseudo source value.

Implement target specific parsing of immediate mnemonics. The mnemonic is dot seperated strings.

Parse out the target's MachineFunctionInfo from the YAML reprsentation.

Implement the PassRegistrationListener callbacks used to populate our map

Examine the instruction number of this MachineInstr. May be zero if it hasn't been assigned a number yet.

Returns an iterator range over all physical register and mask operands for \p MI and bundled instructions. This also skips any debug operands.

Pop the last finalization callback from the finalization stack. NOTE: Temporary solution until Clang CG is gone.
