; Function Attrs: nounwind
; Offset folding is an optimization done for global variables with relocations,
; which allows you to store the offset in the r_addend of the relocation entry.
; The offset is apllied to the variables address at link time, which eliminates
; the need to emit shader instructions to do this calculation.
; We don't use relocations for local memory, so we should never fold offsets
; for local memory globals.
