Note
Further work is being tracked in #213033

Description of changes

The commit messages in this PR have more details but at a high level this PR contains a few different kinds of changes:

introduces llvmPackages_15
switching to using clang from this package set to bootstrap libcxx, sidestepping some of the issues we've seen with older LLVM package sets
switches to ninja where possible
re-enables Polly by default
enables the LLVM tests on macOS (x86_64 and aarch64)
miscellaneous fixes (lldb, manpages) and updates (LLVM license, dropping some flags we don't need anymore)
mostly mechanical changes to make it easier to override the monorepo source used in the package set (the last two commits)

TODOs:

Checks:

llvmPackages_15.*
passthru tests
test cross / use as a cross compiler with this script
- only focusing on this passing eval successfully for now
  - i.e.:
    - nix path-info --file ./test.nix --derivation
    - nix path-info --file ./test.nix --derivation --arg systems '[ "aarch64-darwin" "x86_64-darwin" ]' --arg testStdenvPackages '[]'
- and checking that the following don't regress:
  - pkgsCross.x86_64-freebsd.boost (with llvmPackages = llvmPackages_15)
    - i.e. nix build --expr '(import ./. { system = "x86_64-linux"; overlays = [(f: p: { llvmPackages = f.llvmPackages_15; })]; }).pkgsCross.x86_64-freebsd.boost'
    - this is currently broken in libcxx
rdeps with nixpkgs-review
- not applicable since we're not bumping llvmPackages_latest

Closes #191132.

With ab9d3df, libcxx-abi (and the rest of llvmPackages_15) builds fine on aarch64-linux as well as x86_64-linux. Darwin is now hitting an unrelated issue in compiler-rt; I'll tackle that next.

After that:

Fixed one compiler-rt build issue, hit another one.

compiler-rt's build now attempts to detect whether the ld used automatically does codesigning, based on version. Our cctools ld is too old for this but postLinkSignHook handles codesigning for us, regardless.

Unfortunately there doesn't seem to be a way to communicate this to the compiler-rt build machinery. In the interest of avoiding making another patch, I tried to add sigtool to the derivation and just let the compiler-rt build sign some dylibs twice but unfortunately compiler-rt's build uses --sign instead of -s which the sigtool in nixpkgs has not been updated to support.

I opened a PR for this (#194994) but given that sigtool has many transitive deps and that that PR is likely to trigger many rebuilds I think it's probably faster to just add a compiler-rt patch.

With 974ea1c this now builds on aarch64-darwin.

Testing x86_64-darwin now; hopefully it Just Works 🤞.

Update: lldb fails to build on x86_64-darwin; it's failing on #include <bsm/audit_session.h> and CPU_SUBTYPE_ARM64E not being present in mach/machine.h 😕

`<bsm/audit_session.h>`

This isn't an issue on aarch64-darwin because we use a newer SDK there:

nixpkgs/pkgs/top-level/darwin-packages.nix

Line 45 in 4a1fb3a

    
           apple_sdk = if stdenv.hostPlatform.isAarch64 then apple_sdk_11_0 else apple_sdk_10_12;

This is the change in upstream causing the issue: llvm/llvm-project@b945b62

lldb appears to only use AU_SESSION_FLAG_HAS_GRAPHIC_ACCESS from audit_session.h which, worst case, would be easy to stub or patch out.

Fortunately, this header is available in the macOS 10.12 SDK (i.e. nixpkgs.darwin.apple_sdk.sdk.dev). Is it okay for me to depend on this header? This was the only precedent in nixpkgs I could find:

nixpkgs/pkgs/development/libraries/webkitgtk/default.nix

Line 168 in 299ec2c

    
                 install -Dm444 "${lib.getDev apple_sdk.sdk}"/include/libproc.h "$out"/include/libproc.h

`CPU_SUBTYPE_ARM64E`

For CPU_SUBTYPE_ARM64E I am not sure why we're just hitting this issue now; it appears to have been added in LLVM 13? llvm/llvm-project@479b672

Edit: oh, of course; lldb is marked as broken for LLVM 13 and 14:

nixpkgs/pkgs/development/compilers/llvm/13/lldb/default.nix

Line 105 in 88a2353

broken = stdenv.isDarwin;

nixpkgs/pkgs/development/compilers/llvm/14/lldb/default.nix

Line 119 in 299ec2c

    
           broken = stdenv.isDarwin; # error: use of undeclared identifier 'CPU_SUBTYPE_ARM64E'

It's not marked as broken in llvmPackages_git but I'm willing to bet that has the same issue.

Fixed in 040efed and opened #195013 to fix lldb 14 and lldb 13 on macOS x86_64.

None of the patches required any touch-up; the only change of note is: - due to changes in the libc++/libc++abi build (https://reviews.llvm.org/D120719 and https://reviews.llvm.org/D131037) we have to add an extra build option to the libc++ header only build that sidesteps bits of the libc++ build config that assume libc++-abi is present in the build: https://github.com/llvm/llvm-project/blob/4f827318e3e8ccab4ff131e06234caa827e91e4e/libcxx/src/CMakeLists.txt#L255-L256 Rather than maintaining a precise set of build options that let us dodge referencing libc++-abi variables in the libc++ header only build, we set `LIBCXX_CXX_ABI` to `none`, as suggested by @lovesegfault.
