## New entry point into our C/C++ code generator. Ideally
## somebody would rewrite the old backend (which is 8000 lines of crufty Nim code)
## to work on packed trees directly and produce the C code as an AST which can
## then be rendered to text in a very simple manner. Unfortunately nobody wrote
## this code. So instead we wrap the existing cgen.nim and its friends so that
## we call directly into the existing code generation logic but avoiding the
## naive, outdated `passes` design. Thus you will see some
## `useAliveDataFromDce in flags` checks in the old code -- the old code is
## also doing cross-module dependency tracking and DCE that we don't need
## anymore. DCE is now done as prepass over the entire packed module graph.

====================================
Incremental Recompilations
====================================
We split the Nim compiler into a frontend and a backend.
The frontend produces a set of `.rod` files. Every `.nim` module
produces its own `.rod` file.
- The IR must be a faithful representation of the AST in memory.
- The backend can do its own caching but doesn't have to. In the
current implementation the backend also caches its results.
Advantage of the "set of files" vs the previous global database:
- By construction, we either read from the `.rod` file or from the
`.nim` file, there can be no inconsistency. There can also be no
partial updates.
- No dependency to external packages (SQLite). SQLite simply is too
slow and the old way of serialization was too slow too. We use a
format designed for Nim and expect to base further tools on this
file format.
References to external modules must be (moduleId, symId) pairs.
The symbol IDs are module specific. This way no global ID increment
mechanism needs to be implemented that we could get wrong. ModuleIds
are rod-file specific too.
Global state
------------
There is no global state.
Rod File Format
---------------
It's a simple binary file format. `rodfiles.nim` contains some details.
Backend
-------
Nim programmers have to come to enjoy whole-program dead code elimination,
by default. Since this is a "whole program" optimization, it does break
modularity. However, thanks to the packed AST representation we can perform
this global analysis without having to unpack anything. This is basically
a mark&sweep GC algorithm:
- Start with the top level statements. Every symbol that is referenced
from a top level statement is not "dead" and needs to be compiled by
the backend.
- Every symbol referenced from a referenced symbol also has to be
compiled.
Caching logic: Only if the set of alive symbols is different from the
last run, the module has to be regenerated.

File diff suppressed because it is too large Load Diff

# The Nim Compiler
# (c) Copyright 2020 Andreas Rumpf

# See the file "copying.txt", included in this
# distribution, for details about the copyright.
#
## Low level binary format used by the compiler to store and load various AST
## and related data.
##
## NB: this is incredibly low level and if you're interested in how the
## compiler works and less a storage format, you're probably looking for
## the `ic` or `packed_ast` modules to understand the logical format.
from std/typetraits import supportsCopyMem
when defined(nimPreviewSlimSystem):
import std/[syncio, assertions]
import std / tables
## Overview
## ========
## `RodFile` represents a Rod File (versioned binary format), and the
## associated data for common interactions such as IO and error tracking
## (`RodFileError`). The file format broken up into sections (`RodSection`)
## and preceded by a header (see: `cookie`). The precise layout, section
## ordering and data following the section are determined by the user. See
## `ic.loadRodFile`.
##
## A basic but "wrong" example of the lifecycle:
## ---------------------------------------------
## 1. `create` or `open` - create a new one or open an existing
## 2. `storeHeader` - header info
## 3. `storePrim` or `storeSeq` - save your stuff
## 4. `close` - and we're done
##
## Now read the bits below to understand what's missing.
##
## ### Issues with the Example
## Missing Sections:
## This is a low level API, so headers and sections need to be stored and
## loaded by the user, see `storeHeader` & `loadHeader` and `storeSection` &
## `loadSection`, respectively.
##
## No Error Handling:
## The API is centered around IO and prone to error, each operation checks or
## sets the `RodFile.err` field. A user of this API needs to handle these
## appropriately.
##
## API Notes
## =========
##
## Valid inputs for Rod files
## --------------------------
## ASTs, hopes, dreams, and anything as long as it and any children it may have
## support `copyMem`. This means anything that is not a pointer and that does not contain a pointer. At a glance these are:
## * string
## * objects & tuples (fields are recursed)
## * sequences AKA `seq[T]`
##
## Note on error handling style
## ----------------------------
## A flag based approach is used where operations no-op in case of a
## preexisting error and set the flag if they encounter one.
##
## Misc
## ----
## * 'Prim' is short for 'primitive', as in a non-sequence type
