Tracking issue: OS X (aarch64) build/test status

cdleary commented 1 month ago

Just an issue to track and take notes on the current (merged to google/xls) status of OS X support. Taking notes in an issue in the google/xls repo as it's (currently) canonical mainline. This is all work-aroundable, but my intent is to get mainline into a state where it "usually" works on OS X (via fixes and PRs if it happens to break).

The hermetic LLVM toolchain does not work on OS X
But if you comment out the registration of LLVM toolchain from the WORKSPACE file, almost everything works with the clang-15 installation that's present on latest OS X
iverilog build doesn't work, which I think is understandable because we did a lot of hacktastic stuff to make it work on Linux
current grpc dep (at HEAD) has issues
AoT compilations fail here: https://github.com/google/xls/blob/ec4df616bc8b3acd25db670259316e675b53edc9/xls/jit/aot_compiler.cc#L99

$ clang --version
Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: arm64-apple-darwin23.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Note that if you don't comment out the hermetic toolchain registration it gives you an error indicating "you invoked llvm-ar with invalid command line arguments". Aside: I often use //xls/ir:bits_test as a simple canary target for a binary to build/test.

grpc issue:

looks like https://github.com/abseil/abseil-cpp/issues/1614, should be fixed w/ https://github.com/grpc/grpc/commit/bc044174401a0842b36b8682936fc93b5041cf88

should we try bumping grpc to https://github.com/grpc/grpc/releases/tag/v1.64.0 ?https://github.com/google/xls/blob/ec4df616bc8b3acd25db670259316e675b53edc9/dependency_support/load_external.bzl#L269-L283

Thanks for the pointer @proppy ! I'll try to do the dependency bump dance in a bit here and see how it goes.

hzeller commented 1 month ago

The current 1.64.0 still has the c++20 regression (but a fix is in at head and they plan to backport it to 1.64).

For us, to update 1.64.0, we can use that release and then cherry-pick the fixing patch and applying it in the load_external.bzl.

Note, when updating grpc, this will also require to update or-tools last time I checked, so it might be a bit involved as that dependency also has not updated in a while.
