# Script for defining a new op using SPIR-V spec from the Internet.

# ./define_inst.sh <filename> <baseclass> (<opname>)*

# <filename> is required, which is the file name of MLIR SPIR-V op definitions

# <baseclass> is required. It will be the direct base class the newly defined
# op will drive from.
# If <opname> is missing, this script updates existing ones in <filename>.

# For example:
# ./define_inst.sh SPIRVArithmeticOps.td ArithmeticBinaryOp OpIAdd
# ./define_inst.sh SPIRVLogicalOps.td LogicalOp OpFOrdEqual
