2022-07-03lib.systems.examples: canonicalize MIPS triplesAlyssa Ross1-14/+12
In Nixpkgs, we assume that the "config" field is a canonicalized GNU triple. I noticed that non-canonical values were being used here, because the pkgsCross.mips64el-linux-gnu triples did not contain the vendor field, but the pkgsCross.mips64el-linux-gnu.pkgsStatic did. Here, I've run all the MIPS triples in lib.systems.examples through config.sub to canonicalize them. I think this will avoid nasty surprises in future. Tested by building Nix and the bootstrap files for pkgsCross.mips64el-linux-gnu.

2022-05-25lib/systems/inspect.nix: remove isPowerPCAdam Joseph1-1/+0
Very confusingly, the `isPowerPC` predicate in `lib/systems/inspect.nix` does *not* match `powerpc64le`! This is because `isPowerPC` is defined as isPowerPC = { cpu = cpuTypes.powerpc; }; Where `cpuTypes.powerpc` is: { bits = 32; significantByte = bigEndian; family = "power"; }; This means that the `isPowerPC` predicate actually only matches the subset of machines marketed under this name which happen to be 32-bit and running in big-endian mode which is equivalent to: with stdenv.hostPlatform; isPower && isBigEndian && is32bit This seems like a sharp edge that people could easily cut themselves on. In fact, that has already happened: in `linux/kernel/common-config.nix` there is a test which will always fail: (stdenv.hostPlatform.isPowerPC && stdenv.hostPlatform.is64bit) A more subtle case of the strict isPowerPC being used instead of the moreg general isPower accidentally are the GHC expressions: Update pkgs/development/compilers/ghc/8.10.7.nix Update pkgs/development/compilers/ghc/8.8.4.nix Update pkgs/development/compilers/ghc/9.2.2.nix Update pkgs/development/compilers/ghc/9.0.2.nix Update pkgs/development/compilers/ghc/head.nix Since the remaining legitimate use sites of isPowerPC are so few, remove the isPowerPC predicate completely. The alternative expression above is noted in the release notes as an alternative. Co-authored-by: sternenseemann <sternenseemann@systemli.org>

2022-05-23lib.systems.elaborate: expose canExecute predicate over isCompatiblesternenseemann1-2/+4
canExecute is like isCompatible, but also checks that the Kernels are _equal_, i.e. that both platforms use the same syscall interface. This is crucial in order to actually be able to execute binaries for the other platform. isCompatible is dropped, since it has changed semantically and there's no use case left in nixpkgs.
2022-05-23lib/systems/parse: don't consider mode switching CPUs compatiblesternenseemann1-13/+6
Since we (exclusively) use isCompatible to gauge whether platform a can execute binaries built for platform b, mode switching CPUs are not to be considered compatible for our purposes: Switching the mode of a CPU usually requires a reset. At the very least we can't execute a mix of executables for the two modes which would usually be the case in nixpkgs where we may want to execute buildInputs for the hostPlatform in addition to nativeBuildInputs for the buildPlatform.
2022-05-23lib.systems: remove supported, replace with flakeExposedsternenseemann3-27/+39
Since the list only gates the platforms the nixpkgs flake exposes packages to build on, the `hydra` label made little sense. It was also only used for this purpose, so the `tier*` attributes were largely unnecessary. To reflect the intention more accurately, we expose `lib.systems.flakeExposed` and use it to gate flake.nix's system list.

2022-05-03platforms.nix: use {} on failed detection instead of silently assuming pcAdam Joseph1-2/+2
This patch causes the autodetection code in lib/systems/platforms.nix to return {} if it cannot detect the platform and one of the platform.nix-detection-provided attributes (linux-kernel, gcc, and rustc) are accessed, rather than silently assuming the "pc" platform as was previously done. It is definitely safe to assume that code using these attributes is prepared to deal with `gcc` and `rustc` not being defined, because many of the working entries in this file don't define it. Regarding `linux-kernel` the situation is less certain, but some code (`lib/systems/default.nix` for example) is already designed to deal with that attribute being missing. At worst it would result in an "attribute not found" error. While adding mips64el bootstrap support to nixpkgs, the silent assumption that mips64el routers are actually Intel PCs caused significant frustration. This commit removes that assumption in order to save people who port nixpkgs to new platforms in the future from this frustration.

2022-04-27lib/systems/platforms.nix: fix broken mips32 detectionAdam Joseph1-1/+1
Prior to this commit, nixpkgs would assume that every little-endian mips32 system was a "fuloong2f_n32". Not only are there plenty of mips32 chips other than the fuloong, but the fuloong is actually a mips64 chip! Note that the "n32" ABI is (confusingly) an ABI for 64-bit mips chips (like the "x32" ABI for amd64 chips -- both are ABIs which use 32-bit pointers on an otherwise-64-bit system). This error causes far-ranging problems. One of them was particularly difficult to track down: it caused GCC to select 128-bit `long double` types, which is invalid for the mips32 ABI. This isn't noticed until you try to build musl-libc, which is careful to check for these things. Prior to this commit, nix-build . -A pkgsCross.mipsel-linux-gnu.pkgsStatic.hello would fail. With this commit and #170736, it succeeds.
2022-04-27lib/systems/platforms.nix: use "32" instead of "o32" for mips32 ABIAdam Joseph1-2/+2
There is only one ABI for 32-bit MIPS chips. Before mips64, it didn't really have a name. The 64-bit MIPS ABI comes in two flavors, "n64" and "n32". It is commonplace to refer to the old 32-bit ABI as "o32" (MIPS and SGI documents do this). However, when configuring gcc, one must use --with-abi=32, not --with-abi=o32. Let's keep GCC happy with this commit.

2022-04-10lib/systems/inspect.nix: add isPower64Adam Joseph1-0/+1
This commit adds an `isPower64` predicate to the two existing predicates for this architecture (`isPower` and `isPowerPC`). Note that `isPowerPC` matches only 32-bit machines, whereas `isPower` matches both 64-bit and 32-bit machines. Prior to this commit there was no single `isXXX` predicate for `powerpc64le`.

2022-03-10lib/systems: add mips64el definitionsAdam Joseph6-4/+73
MIPS has a large space of {architecture,abi,endianness}; this commit adds all of them to lib/systems/platforms.nix so we can be done with it. Currently lib/systems/inspect.nix has a single "isMips" predicate, which is a bit ambiguous now that we will have both mips32 and mips64 support, with the latter having two ABIs. Let's add four new predicates (isMips32, isMips64, isMips64n32, and isMips64n64) and treat the now-ambiguous isMips as deprecated in favor of the more-specific predicates. These predicates are used mainly for enabling/disabling target-specific workarounds, and it is extremely rare that a platform-specific workaround is needed, and both mips32 and mips64 need exactly the same workaround. The separate predicates (isMips64n32 and isMips64n64) for ABI distinctions are, unfortunately, useful. Boost's user-scheduled threading (used by nix) does does not currently supports mips64n32, which is a very desirable ABI on routers since they rarely have more than 2**32 bytes of DRAM.

2021-12-16lib.systems.supported: remove aarch64-darwin from Tier 3 liststernenseemann1-2/+3
While it is a fact of life that aarch64-darwin is built on Hydra, it has never formally been elevated from the Tier 7 state it was originally assigned in RFC 0046. Since platform Tier status is not only descriptive, but also normative, a consensus to commit to supporting aarch64-darwin would need to be reached.
