Hi all,

I have a problem in building LLVM with these parameter.

cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind" -DLLVM_ABI_BREAKING_CHECKS=FORCE_OFF -DLLVM_INCLUDE_EXAMPLES=OFF -DLLVM_INCLUDE_TESTS=OFF -DBUILD_SHARED_LIBS=True -DCMAKE_INSTALL_PREFIX=$LLVM_PREFIX -DLLVM_BUILD_TESTS=False -DDEFAULT_SYSROOT=$RISCV_TOOLCHAIN_PATH/riscv32-unknown-elf -DLLVM_DEFAULT_TARGET_TRIPLE="riscv32-unknown-elf" -DLLVM_TARGETS_TO_BUILD="RISCV" ../llvm

riscv-toolchain-path is build by this project.

The problem that I face during build process is that it can not link library lib/libLLVMObject.so. The error log is:

[0/5] Performing configure step for 'runtimes'

ninja: build stopped: subcommand failed.

I do not have any idea about the problem and how solve this because everything seems to be ok. Is there anybody who has an idea how I can solve this issue?

add testcase for llvm segfault (issue #889)
263323d 
The segmentation fault can be observed with llvm-10, llvm-11 and llvm-12
and seems to be fixed in llvm-13. It happens on the architectures armhf
and armel (both 32-bit) always and on x86_64 sporadically.
The test segfaults only on the first run (i.e. the kernel is not yet in
pocl's kernel cache) while it passes on subsequent execution (with
something already in the kernel cache), emitting only some llvm
diagnostics:

inlinable function call in a function with debug info must have a !dbg location
  %11 = call i32 @_Z12get_local_idj(i32 0)
inlinable function call in a function with debug info must have a !dbg location
  %19 = call i32 @_Z12get_local_idj(i32 1)
inlinable function call in a function with debug info must have a !dbg location
  %27 = call i32 @_Z12get_local_idj(i32 2)

The backtrace of the segmentation fault as observed with llvm-10 and pocl 1.6:
