Atomic language features comparison - a compiler developer's point of view

Languages explained

__sync builtins

• made up by Intel for the Itanium ABI
• legacy
• all sequentially consistent
• operate on arbitrary integer-based types

import subprocess, functools

# Do you often use Python in place of bash?
# Do you want to simply just run thing and get output?
# Here's a wrapper function for automating whatever you'd like.
# Use shell=True and you can use pipes and env vars!
# Throw in a string! Throw in an arg list! Throw in a pathlib.Path maybe!
# Use it everywhere! 3 bazillion devices run r('foo')!
r = functools.partial(subprocess.check_output, text=True)

Big $macc with fries

Oddities of the yosys $macc cell. To all "losses" in modifications, add in your head the necessity of creating a v2 cell with compatibility wrapping of some kind.

Factor length field has variable bit length

Length of the factor length fields, known as variable num_bits in docs and code, is recorded in the CONFIG parameter and capped at effectively 15. We can set it to const 16 for example, simplifying CONFIG parsing.

Gains: simplifies from_cell, to_cell, simlib.v,
