each asm macro ran in 1uS (4uS for one pass). That's not bad considering the chunk of asm in there.
means the compiler is making nicely optimised code
I'm sure dt would have had some nice tools , my disassembler won't function any longer it steeps back to windows98 days , but since I gave up hand assembly its not missed that much .
imho most compliers do a reasonable job except maybe the free version of xc8 which is apparently deliberately de-optimised
