I have uploaded:

SHA256 (clang+llvm-10.0.1-rc1-amd64-unknown-freebsd11.tar.xz) = 4dbe2041e8aa80ba2b908946052bd4bb20733422707277aa7c297980ed8cd92c
SHA256 (clang+llvm-10.0.1-rc1-i386-unknown-freebsd11.tar.xz) = 5fad007fdabe085de126513875a8e601b1f341889eb36423d2980dd3d34b1d80

but none of the regression tests could run, due to a lit/googletest exception:

llvm-lit: /home/dim/llvm/10.0.1/rc1/llvm-project/llvm/utils/lit/lit/formats/googletest.py:43: warning: unable to discover google-tests in '/home/dim/llvm/10.0.1/rc1/Phase3/Release/llvmCore-10.0.1-rc1.obj/tools/mlir/unittests/Dialect/SPIRV/./MLIRSPIRVTests': Command '['/home/dim/llvm/10.0.1/rc1/Phase3/Release/llvmCore-10.0.1-rc1.obj/tools/mlir/unittests/Dialect/SPIRV/./MLIRSPIRVTests', '--gtest_list_tests']' returned non-zero exit status 1.. Process output: b''

Running the MLIRSPIRVTests executable shows the actual problem:

$ /home/dim/llvm/10.0.1/rc1/Phase3/Release/llvmCore-10.0.1-rc1.obj/tools/mlir/unittests/Dialect/SPIRV/./MLIRSPIRVTests
Shared object "libc++abi.so.1" not found, required by "MLIRSPIRVTests"

On FreeBSD we use libcxxrt, not libc++abi. Does anybody have an idea why this appears to have changed between 10.0.0 and 10.0.1? And if so, how I tell the build not to link against libc++abi?
