I noticed in test-case gdb.reverse/map-to-same-line.exp, that the end of main: ... 00000000004102c4 <end_of_sequence>: 4102c4: 52800000 mov w0, #0x0 // #0 4102c8: 9100c3ff add sp, sp, #0x30 4102cc: d65f03c0 ret ... is not described by the line table: ... File name Line number Starting address View Stmt ... map-to-same-line.c 54 0x4102ac x map-to-same-line.c - 0x4102c4 ... Fix this by ending the line table at $main_end. Likewise in a few other test-cases, found using: ... $ find gdb/testsuite/ -type f \ | xargs grep -B1 DW_LNE_end_sequence \ | grep set_address \ | egrep -v "_end|_len" ... Tested on aarch64-linux.
