[llvm-dev] Mangled SPIR function name

[Frank Winter via llvm-dev]

"clang -triple spir64 .." would generate from an OpenCL statement like

uint idx = get_global_id(0);

something like this:

%0 =  call i64 @_Z13get_global_idj(i32 0)

Note it generates the mangled form.

Using only LLVM builder tools, i.e. no clang, how can I generate this mangled form?

Using  Module::getOrInsertFunction( "_Z13get_global_idj" , .... ) seems little portable.

Assuming that I'm building a "spir_kernel", is the above (simple) solution safe enough?

Frank
