NodeType

enum llvm::AVRISD::NodeType

AVR Specific DAG Nodes.

Enumerator
FIRST_NUMBER	Start the numbering where the builtin ops leave off.
RET_GLUE	Return from subroutine.
RETI_GLUE	Return from ISR.
CALL	Represents an abstract call instruction, which includes a bunch of information.
WRAPPER	A wrapper node for TargetConstantPool, TargetExternalSymbol, and TargetGlobalAddress.
LSL	Logical shift left.
LSLBN	Byte logical shift left N bits.
LSLWN	Word logical shift left N bits.
LSLHI	Higher 8-bit of word logical shift left.
LSLW	Wide logical shift left.
LSR	Logical shift right.
LSRBN	Byte logical shift right N bits.
LSRWN	Word logical shift right N bits.
LSRLO	Lower 8-bit of word logical shift right.
LSRW	Wide logical shift right.
ASR	Arithmetic shift right.
ASRBN	Byte arithmetic shift right N bits.
ASRWN	Word arithmetic shift right N bits.
ASRLO	Lower 8-bit of word arithmetic shift right.
ASRW	Wide arithmetic shift right.
ROR	Bit rotate right.
ROL	Bit rotate left.
LSLLOOP	A loop of single logical shift left instructions.
LSRLOOP	A loop of single logical shift right instructions.
ROLLOOP	A loop of single left bit rotate instructions.
RORLOOP	A loop of single right bit rotate instructions.
ASRLOOP	A loop of single arithmetic shift right instructions.
BRCOND	AVR conditional branches. Operand 0 is the chain operand, operand 1 is the block to branch if condition is true, operand 2 is the condition code, and operand 3 is the flag operand produced by a CMP or TEST instruction.
CMP	Compare instruction.
CMPC	Compare with carry instruction.
TST	Test for zero or minus instruction.
SWAP	Swap Rd[7:4] <-> Rd[3:0].
SELECT_CC	Operand 0 and operand 1 are selection variable, operand 2 is condition code and operand 3 is flag operand.
