Background
I'm working on a JIT backend for AtomVM, an alternative virtual machine for BEAM languages (Erlang, Elixir, Gleam), and I adopted Dwarf as the format for debugging the JIT-compiled and precompiled code.
BEAM languages are pretty mature and can already include debug info in an alternative proprietary format, but live debugging is a work in progress for both BEAM (the primary virtual machine) and AtomVM. AtomVM being focused on micro controllers, gdb is the natural tool and Dwarf the best format.
Proposal
I would like to propose that new language constants be added for the three of them (Erlang, Elixir and Gleam) in v6.
Erlang
- Default lower bound: 1
- Version scheme: VVMMPP
Elixir
- Default lower bound: 1
- Version scheme: VVMMPP
Gleam
- Default lower bound: 0
- Version scheme: VVMMPP
2025-10-07: Changed version schemes for Erlang and Elixir to VVMMPP.
