Matthew Bauer	9abff4af4f	wasm: init cross target ... Adds pkgsCross.wasm32 and pkgsCross.wasm64. Use it to build Nixpkgs with a WebAssembly toolchain. stdenv/cross: use static overlay on isWasm isWasm doesn’t make sense dynamically linked.	2019-04-23 21:48:57 -04:00
Matthew Bauer	8e25da0beb	cross/tests: add llvm-based tests	2019-02-26 19:46:24 -05:00
Matthew Bauer	b86e62d30d	llvm: support cross compilation with useLLVM flag ... You can build (partially) with LLVM toolchain using the useLLVM flag. This works like so: nix-build -A hello --arg crossSystem '{ system = "aarch64-unknown-linux-musl"; useLLVM = true }' also don’t separate debug info in lldClang It doesn’t work currently with that setup hook. Missing build-id?	2019-02-26 19:45:35 -05:00
Matthew Bauer	9c8fd41224	treewide: add emulator to platform ... 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.	2018-11-29 19:15:30 -06:00
