1; In the RISC-V architecture, the .text section is subject to2; relaxation, meaning the start address of each function can change3; during the linking process. Therefore, the .debug_rnglists.dwo4; section must obtain function's start addresses from the .debug_addr5; section.6 7; Generally, a function's body can be relaxed (for example, the8; square() and main() functions in this test, which contain call9; instructions). For such code ranges, the linker must place the10; start and end addresses into the .debug_addr section and use11; the DW_RLE_startx_endx entry form in the .debug_rnglists.dwo12; section within the .dwo file.13 14; However, some functions may not contain any relaxable instructions15; (for example, the boo() function in this test). In these cases,16; it is possible to use the more space-efficient DW_RLE_startx_length17; range entry form.18 19; RUN: rm -rf %t && split-file %s %t && cd %t20 21; RUN: llc -dwarf-version=5
