Now we have public headers arranged as follows: $SPIRV_TOOLS_ROOT/include/spirv-tools/libspirv.h $SPIRV_TOOLS_ROOT/include/spirv/spirv.h $SPIRV_TOOLS_ROOT/include/spirv/GLSL.std.450.h $SPIRV_TOOLS_ROOT/include/spirv/OpenCL.std.h A project should use -I$SPIRV_TOOLS_ROOT/include and then #include "spirv-tools/libspirv.h" The headers from the SPIR-V Registry can be accessed as "spirv/spirv." for example. The install target should also install the headers from the SPIR-V Registry. The libspirv.h header is broken otherwise. The SPIRV-Tools library depends on the headers from the SPIR-V Registry. The util/bitutils.h and util/hex_float.h are pulled into the internal source tree. Those are not part of the public API to SPIRV-Tools.
