;; Test that .loc directives inside inline asm preserve inlined_at context.
;; When inline asm appears inside an inlined function, the .loc directives
;; injected for inline asm instructions must include function_name and
;; inlined_at attributes to avoid stripping the inlining context.
;;
;; Simplified from:
;;   __device__ int local_func(int p) {
;;     int dummy;
;;     asm volatile("ld.local.u32 %0, [0];" : "+r"(dummy));
;;     return 2 * p;
;;   }
;;   __global__ void kernel() {
;;     int r = local_func(threadIdx.x);
;;   }
