objasm and STM32

Is it possible to build code, a binary lump, for the STM32 microcontroller using objasm?

You have the DDE, so why not give it a go and find out yourself?

There is support for Thumb-1, but for writing low-level code on an M-profile CPU that’s going to be pretty useless since there’s a lot of functionality missing (e.g. MRS, MSR). So the big question is whether you can get it to produce Thumb-2 output.

armasm’s docs suggest that you can select Thumb-2 support either via the --16 command line arg (for pre-UAL syntax) or --thumb (for UAL syntax). So try throwing those at objasm and see what it says.

Also work checking the output of --cpu=list to see if any M-profile CPUs/architectures turn up.
