The llama egg declares a dependency on srfi-4 which is actually part of CHICKEN itself and not an
egg. To salvage it, we remove such bogus dependencies now.
Swift now works fine with standard environments using GCC or other
versions of LLVM. Some packages, like components of Swift itself or
others that combine Swift with features like C++ modules or C blocks,
may still need to use an LLVM‐based standard environment, but we
do not need to enforce a uniform `swiftPackages.stdenv` any more.
libc++ only supports a limited range of Clang versions, so this was
relying on the LLVM version corresponding to the one used in Swift’s
fork. Since Swift builds its own LLVM 15 anyway, we can simply install
the required libc++ headers along with it.
Swift needs Clang to link with. The linker patch breaks linking
when using Swift with a GCC‐based standard environment.
Similarly, the internal Clang headers in the resource directory are
coupled to the corresponding version of Clang. The resource root patch
caused Swift’s Clang to use the resource directory from the version
of Clang used in the build environment, which is only compatible if
the versions match.
Instead, hard‐code the Clang path in the patches and wrappers.
Honestly I did this in the middle of trying things and then forgot
about it, and I just don’t feel like bootstrapping the whole thing
again to drop this commit.
The GPL-2.0-with-classpath-exception is deprecated in spdx and the exception Classpath-exception-2.0 should be used instead.
Other Classpath license hace also benn replaced with it.
Fixes `libunwind` from not being included due to improper usage of
`lib.optional` by passing a list instead of a single item. Drops the
hack for `llvmPackages` since just passing it through works now.
Add `identifiers` attr to `meta` attribute with following attrs:
* `cpe` with the full CPE string when available
* `possibleCPEs` with the list of potential CPEs when not all
information is provided
* `cpeParts` with the destructured CPE string, allowing to override it
whenever needed
* `v1` attribute set with `cpe` and `cpeParts` from above and a
guarantee of a backwards-compatible interface
