Yeah–this is just a shortcut:

Ok, so if you choose a target among the below list,
MICRO_SUPPORTED_MODELS = {
"host": [],
"atsamd51": ["-mcpu=cortex-m4"],
"cxd5602gg": ["-mcpu=cortex-m4"],
"esp32": [],
"imxrt10xx": ["-mcpu=cortex-m7"],
"mps2_an521": ["-mcpu=cortex-m33"],
"nrf52840": ["-mcpu=cortex-m4"],
"nrf5340dk": ["-mcpu=cortex-m33"],
"sam3x8e": ["-mcpu=cortex-m3"],
"stm32f746xx": ["-mcpu=cortex-m7", "-march=armv7e-m"],
"stm32l4r5zi": ["-mcpu=cortex-m4"],
"zynq_mp_r5": ["-mcpu=cortex-r5"],
}
it means you get C code(not objects or executables compiled by LLVM) anyway
right? Could you tell me why this list even exists? As long as I can see, TVM
and micro TVM require us to specify 'target', but they don't need to know what
the target is for code generation, even when they do AutoTVM.
To run some tutorials, since they use zephyr, we need to specify 'target' and
'board'. But this is to let zephyr know what board it flashes the executables
to, and on TVM side, the information on 'target' doesn't seem to be used...
