* add generic x86_32 support
- Add support for i386-i586.
- Add `isx86_32` predicate that can replace most uses of `isi686`.
- `isi686` is reinterpreted to mean "exactly i686 arch, and not say i585 or i386".
- This branch was used to build working i586 kernel running on i586 hardware.
* revert `isi[345]86`, remove dead code
- Remove changes to dead code in `doubles.nix` and `for-meta.nix`.
- Remove `isi[345]86` predicates since other cpu families don't have specific model predicates.
* remove i386-linux since linux not supported on that cpu
eabihf is an abi that can be used with ARM architectures that support
the “hard float”. It should probably only be used with ARM32 when you
are absolutely sure your binaries will run on ARM systems with a FPU.
Also, add an example "armhf-embedded" to match the preexisting
arm-embedded system. qmk_firmware needs hard float in a few places, so
add them here to get that to work.
Fixes #51184
You can use stdenv.hostPlatform.emulator to get an executable that
runs cross-built binaries. This could be any emulator. For instance,
we use QEMU to emulate Linux targets and Wine to emulate Windows
targets. To work with qemu, we need to support custom targets.
I’ve reworked the cross tests in pkgs/test/cross to use this
functionality.
Also, I’ve used talloc to cross-execute with the emulator. There
appears to be a cross-execute for all waf builds. In the future, it
would be nice to set this for all waf builds.
Adds stdenv.hostPlatform.qemuArch attrbute to get the qemuArch for
each platform.
- respect libc’s incdir and libdir
- make non-unix systems single threaded
- set LIMITS_H_TEST to false for avr
- misc updates to support new libc’s
- use multilib with avr
For threads we want to use:
- posix on unix systems
- win32 on windows
- single on everything else
For avr:
- add library directories for avrlibc
- to disable relro and bind
- avr5 should have precedence over avr3 - otherwise gcc uses the wrong one
This has been not touched in 6 years. Let's remove it to cause less
problems when adding new cross-compiling infrastructure.
This also simplify gcc significantly.
binutils expects x86_64-unknown-netbsd<version> (only 3 parts!). Any other combo seems to fail.
Also handle darwin versions similarly.

It wasn’t exactly clear which NDK you were using previously. This adds
an attribute to system that handles what version of the NDK we should
use when building things.

In particular, now the mainline kernel can be built on the RPi 1 as well
(so kernelBaseConfig should always be a mainline defconfig from now on).
And RPi 2 users can now use linux_rpi without doing the
`nixpkgs.config.platform = lib.systems.platforms.raspberrypi2;` dance.
