Autoroute? Is it coming? (Mod edit, short answer is not in the foreseeable future so nothing to see here. ;) )

advanced in things related to bit manipulation, and maybe compilers are not that good at those as they are in general??

I think that regarding to parity bit calculation the C language is to blame, not the compiler. If in C there were parity bit operator it would be obvious to use it and compiler would certainly know how to translate it into assembler.

CAN-bus related task, where very precise timing was important

In our RS485 bus (up to 50 devices) anyone can start transmitting when it needs. Microprocessor UARTs don’t give you information that at that moment no one other just started to transmit so in parallel to UART the other part of interrupted driven code is looking at RXD line.

“who knows, maybe this time I will do better than the compiler?” playing in my mind :‒)

I can imagine, even I have never written a code in assembler (even the book I mentioned here:

SMD assembly: Hot air, plate or oven?

Those time (1994) teachers even in electronic school knew very little about microcontrollers (at least here in Poland). They asked us to allow for HEX edition a program (without PC). We said: Yes, but not HEX editor but assembler editor and we did it just for schools having no computers. Teachers asked for help how they should teach about microcontrollers so we have written a book which then in 1996 got the title “book of the year” from the best electronic magazine those time here. We also di…

was full of assembler examples).
I have only written (around 1990) an assembler itself and for 8051 my brother was using only my assembler. I used 32 bit numbers for internal calculations and my brother used it to calculate RS232 speed based on quartz frequency. He got overflow in that in other assembler he could use (they used 16 bit numbers).
