| | | | | | | | | | | | | | | Another commit, another bugfix. Some snippets from my currently exploding todo list: - always investigate lookup errors immediately. Beyond the root cause, they should never happen at the moment, while we aren't reclaiming memory. we should always return a more precise error message. Usually involving null pointer checks. - on abort, print out stack trace - emit mapping of labels to addresses during survey - store a mapping of symbols somewhere in the code image - stop allocating 1KB per token; expand space for tokens as needed

| | | | | Also bare-bones syntax highlighting for .limg files. Doesn't work when .limg file is first file opened with Vim.
