Convert libs to a fixed-point This does break the API of being able to import any lib file and get its libs, however I'm not sure people did this. I made this while exploring being able to swap out docFn with a stub in #2305, to avoid functor performance problems. I don't know if that is going to move forward (or if it is a problem or not,) but after doing all this work figured I'd put it up anyway :) Two notable advantages to this approach: 1. when a lib inherits another lib's functions, it doesn't automatically get put in to the scope of lib 2. when a lib implements a new obscure functions, it doesn't automatically get put in to the scope of lib Using the test script (later in this commit) I got the following diff on the API: + diff master fixed-lib 11764a11765,11766 > .types.defaultFunctor > .types.defaultTypeMerge 11774a11777,11778 > .types.isOptionType > .types.isType 11781a11786 > .types.mkOptionType 11788a11794 > .types.setType 11795a11802 > .types.types This means that this commit _adds_ to the API, however I can't find a way to fix these last remaining discrepancies. At least none are _removed_.

treewide: isArm -> isAarch32 Following legacy packing conventions, `isArm` was defined just for 32-bit ARM instruction set. This is confusing to non packagers though, because Aarch64 is an ARM instruction set. The official ARM overview for ARMv8[1] is surprisingly not confusing, given the overall state of affairs for ARM naming conventions, and offers us a solution. It divides the nomenclature into three levels: ``` ISA: ARMv8 {-A, -R, -M} / \ Mode: Aarch32 Aarch64 | / \ Encoding: A64 A32 T32 ``` At the top is the overall v8 instruction set archicture. Second are the two modes, defined by bitwidth but differing in other semantics too, and buttom are the encodings, (hopefully?) isomorphic if they encode the same mode. The 32 bit encodings are mostly backwards compatible with previous non-Thumb and Thumb encodings, and if so we can pun the mode names to instead mean "sets of compatable or isomorphic encodings", and then voilà we have nice names for 32-bit and 64-bit arm instruction sets which do not use the word ARM so as to not confused either laymen or experienced ARM packages.

treewide: get rid of platforms.allBut Negative reasoning like `allBut` is a bad idea with an open world of platforms. Concretely, if we add a new, quite different sort of platform, existing packages with `allBut` will claim they work on it even though they probably won't.

lib, stdenv: Check `meta.platforms` against host platform and be open world First, we need check against the host platform, not the build platform. That's simple enough. Second, we move away from exahustive finite case analysis (i.e. exhaustively listing all platforms the package builds on). That only work in a closed-world setting, where we know all platforms we might build one. But with cross compilation, we may be building for arbitrary platforms, So we need fancier filters. This is the closed world to open world change. The solution is instead of having a list of systems (strings in the form "foo-bar"), we have a list of of systems or "patterns", i.e. attributes that partially match the output of the parsers in `lib.systems.parse`. The "check meta" logic treats the systems strings as an exact whitelist just as before, but treats the patterns as a fuzzy whitelist, intersecting the actual `hostPlatform` with the pattern and then checking for equality. (This is done using `matchAttrs`). The default convenience lists for `meta.platforms` are now changed to be lists of patterns (usually a single pattern) in `lib/systems/for-meta.nix` for maximum flexibility under this new system. Fixes #30902
