Run Instructions for llvm-spirv

To translate between LLVM IR and SPIR-V:

1. Execute the following command to translate input.bc to input.spv

   llvm-spirv input.bc
   

2. Execute the following command to translate input.spv to input.bc

   llvm-spirv -r input.spv
   

3. Other options accepted by llvm-spirv

   • -o file_name - to specify output name
   • -spirv-debug - output debugging information
   • -spirv-text - read/write SPIR-V in an internal textual format for debugging purpose. The textual format is not defined by SPIR-V spec.
