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?
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.
fc9644d4c9 accidentally enabled the
sanitizer tests for GCC on Darwin, when fixing that case was never
attempted. Also inverted the condition from broken to working for
clarity.
We already did them on non-mass-rebuild llvm 6. Also, this allows
simplifying the stdenv booting.
We were missing the libcxxabi dep in compile-rt in llvm 6, so fixed that
too.
libgcc of the gcc being built, not the gcc building it.
* Only include a directory in the rpath of an executable/library if it
is actually used. Before, the `/lib' directory of every build input
was added to the rpath, causing many unnecessary retained
dependencies. For instance, Perl has a `/lib' directory, but most
applications whose build process uses Perl don't actually link
against Perl. (Also added a test for this.)
* After building glibc, remove glibcbug, to prevent a retained
dependency on gcc.
* Add a newline after `building X' in GNU Make.

On the downside, the build process of stdenvLinux builds gcc 9 times
(3 x 3 bootstrap stages). That's a bit excessive.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.

checked whether absolute paths passed to gcc/ld refer to the store,
which is wrong: they can also refer to the build tree
(/tmp/nix-...).
* Less static composition in the construction of stdenv-nix-linux:
gcc-wrapper and generic are now passed in as arguments, rather then
referenced by relative path. This makes it easier to hack on a
specific stage of the bootstrap process (before, a change to, e.g.,
generic/setup.sh would cause all bootstrap stages to be redone).

- gcc/ld-wrappers have been factored out into a separate
derivation. This allows a working gcc to be installed in the user
environment. (Previously the Nix gcc didn't work because it
needed a whole bunch of flags to point to glibc.)
- Better modularity: packages can specify hooks into the setup
scripts. For instance, setup no longer knows about the
PKG_CONFIG_PATH variable; pkgconfig can set it up instead.
- gcc not longer depends on binutils. This simplifies the bootstrap
process.
