Is it possible to include a “.a” file in the web IDE?
@joe4465,
I tried the following and it compiled:
__asm__ volatile ("");
It does nothing but you can enter your assembly statements as strings like this:
"ror %[value]\n" << this is a statement borrowed from the arduino ;)
You have to figure the rest out yourself, I haven’t had the time to dive deeper in it 
Good luck!
