[llvm-dev] Polly tests broken

[Alexandre Ganea via llvm-dev]

The polly bot is down for a while and it seems *all* polly tests are broken (tested on Windows with both MSVC & Clang 9), looks like LLVMPolly.dll doesn't build anymore?
Anybody else seeing this?
Using the following cmake command:

cmake -GNinja %ROOT%/llvm -DCMAKE_BUILD_TYPE=Release -DLLVM_OPTIMIZED_TABLEGEN=true -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_LIBXML2=OFF -DCMAKE_C_COMPILER="%VS2017%/bin/HostX64/x64/cl.EXE" -DCMAKE_CXX_COMPILER="%VS2017%/bin/HostX64/x64/cl.EXE" -DCMAKE_LINKER="%VS2017%/bin/HostX64/x64/link.EXE" -DLLVM_USE_CRT_RELEASE=MT -DLLVM_ENABLE_PROJECTS="llvm;clang;lld;clang-tools-extra;compiler-rt;mlir;polly"

The output I'm seeing with ninja check-all:

FAIL: Polly :: Simplify/scalability1.ll (56278 of 59460)
