# I created this YAML starting with this LLVM IR:
#
#   define void @break_cond_is_arg(i32 %arg, i1 %breakcond) {
#   entry:
#     br label %loop
#   loop:
#     %tmp23phi = phi i32 [ %tmp23, %endif ], [ 0, %entry ]
#     %tmp23 = add nuw i32 %tmp23phi, 1
#     %tmp27 = icmp ult i32 %arg, %tmp23
#     br i1 %tmp27, label %then, label %endif
#   then:                                             ; preds = %bb
#     call void @llvm.amdgcn.raw.buffer.store.f32(float undef, <4 x i32> undef, i32 0, i32 undef, i32 0)
#     br label %endif
#   endif:                                             ; preds = %bb28, %bb
#     br i1 %breakcond, label %loop, label %loopexit
#   loopexit:
#     ret void
#   }
#
#   declare void @llvm.amdgcn.raw.buffer.store.f32(float, <4 x i32>, i32, i32, i32 immarg) #0
#
#   attributes #0 = { nounwind writeonly }
#
# I compiled it to a relocatable ELF:
#
#   llc -mtriple=amdgcn -mcpu=gfx1030 llvm/a.ll -filetype=obj -o a.elf
#
# then converted it to YAML:
#
#   obj2yaml a.elf
#
# then manually removed the BB0_1 etc local symbols.
#
# Note that there are two copies of the file:
#   - One as a relocatable object file (zero section addresses)
#   - One as a shared object file (non-zero section addresses)
