llvm/test/DebugInfo/RISCV/relax_dwo_ranges.ll

; In the RISC-V architecture, the .text section is subject to
; relaxation, meaning the start address of each function can change
; during the linking process. Therefore, the .debug_rnglists.dwo
; section must obtain function's start addresses from the .debug_addr
; section.

; Generally, a function's body can be relaxed (for example, the
; square() and main() functions in this test, which contain call
; instructions). For such code ranges, the linker must place the
; start and end addresses into the .debug_addr section and use
; the DW_RLE_startx_endx entry form in the .debug_rnglists.dwo
; section within the .dwo file.

; However, some functions may not contain any relaxable instructions
; (for example, the boo() function in this test). In these cases,
; it is possible to use the more space-efficient DW_RLE_startx_length
; range entry form.
