Is this suffering?
My own attempt at Advent of Code 2020 using x86_64 assembly, assembled with GAs.
For extra pain, I only use 64-bit Linux syscalls and disallow myself the use of the C standard library.
Executables contain both part 1 and part 2. 2 needs to be passed as the second argument to run part 2 of a day:
$ ./day2 # runs part 1
$ ./day2 1 # runs part 1
$ ./day2 2 # runs part 2Utilities in other languages for helping with development (under utils/):
str2val: A tiny C program that shows first 1/2/4/8 bytes of strings as integers.
