# sparrow_modules()
#
# A wrapper for the sparrow_static_module and sparrow_vmvx_module to apply common iree-compile flags
# Parameters:
# NAME: Name of target.
# SRC: Source file to compile into a bytecode module. Support relative path.
# FLAGS: Flags to pass to the translation tool (list of strings).
# C_IDENTIFIER: Identifier to use for generate c embed code.
#     If omitted then no C embed code will be generated.
# TFLITE_OUTPUT: TFLite output array name
# RVV_OFF: Indicate RVV is OFF (default: ON)
# VMVX: Compile VMVX backend
# INLINE_HAL: Use inline HAL.
#
# Examples:
# sparrow_modules(
#   NAME
#     dare_devel
#   SRC
#     "daredevil_quant.tflite"
#   C_IDENTIFIER
#     "daredevil_bytecode_module_static"
#   FLAGS
#     "-iree-input-type=tosa"
# )
#
# sparrow_modules(
#   NAME
#     simple_float_mul
#   SRC
#     "simple_float_mul.mlir"
#   C_IDENTIFIER
#     "simple_float_mul"
#   FLAGS
#     "-iree-input-type=mhlo"
#   RVV_OFF
#   PUBLIC
# )
