1# Test basics of debug_line parsing. This test uses a linker script which 2# ensures the code is placed at the end of a module to test the boundary 3# condition when the final end-of-sequence line table entry points to an address 4# that is outside the range of memory covered by the module. 5 6# REQUIRES: lld 7 8# RUN: llvm-mc -triple x86_64-pc-linux %s -filetype=obj > %t.o 9# RUN: ld.lld --script=%S/Inputs/debug-line-basic.script %t.o -o %t 10# RUN: %lldb %t -o "image dump line-table -v a.c" -o exit | FileCheck %s 11 12 .text 13 .globl _start 14_start: 15# CHECK: Line table for /tmp/a.c 16 .file 1 "/tmp/b.c" 17 .loc 1 0 0 18 nop 19# CHECK-NEXT: 0x0000000000201000: /tmp/b.c, is_start_of_statement = TRUE{{$}} 20 .loc 1 1 0 21 nop 22# CHECK-NEXT: 0x0000000000201001: /tmp/b.c:1, is_start_of_statement = TRUE{{$}} 23 .loc 1 1 1 24 nop 25# CHECK-NEXT: 0x0000000000201002: /tmp/b.c:1:1, is_start_of_statement = TRUE{{$}} 26 .loc 1 2 0 is_stmt 0 27 nop 28# CHECK-NEXT: 0x0000000000201003: /tmp/b.c:2{{$}} 29 .loc 1 2 0 is_stmt 0 basic_block 30 nop 31# CHECK-NEXT: 0x0000000000201004: /tmp/b.c:2, is_start_of_basic_block = TRUE{{$}} 32 .loc 1 2 0 is_stmt 0 prologue_end 33 nop 34# CHECK-NEXT: 0x0000000000201005: /tmp/b.c:2, is_prologue_end = TRUE{{$}} 35 .loc 1 2 0 is_stmt 0 epilogue_begin 36 nop 37# CHECK-NEXT: 0x0000000000201006: /tmp/b.c:2, is_epilogue_begin = TRUE{{$}} 38 .file 2 "/tmp/c.c" 39 .loc 2 1 0 is_stmt 0 40 nop 41# CHECK-NEXT: 0x0000000000201007: /tmp/c.c:1{{$}} 42# CHECK-NEXT: 0x0000000000201008: /tmp/c.c:1, is_terminal_entry = TRUE{{$}} 43 44 .section .text.f,"ax",@progbits 45f: 46 .loc 1 3 0 is_stmt 0 47 nop 48# CHECK-NEXT: 0x0000000000201008: /tmp/b.c:3{{$}} 49# CHECK-NEXT: 0x0000000000201009: /tmp/b.c:3, is_terminal_entry = TRUE{{$}} 50 51 52 .section .debug_str,"MS",@progbits,1 53.Linfo_string1: 54 .asciz "a.c" 55.Linfo_string2: 56 .asciz "/tmp" 57 .section .debug_abbrev,"",@progbits 58 .byte 1 # Abbreviation Code 59 .byte 17 # DW_TAG_compile_unit 60 .byte 0 # DW_CHILDREN_no 61 .byte 19 # DW_AT_language 62 .byte 5 # DW_FORM_data2 63 .byte 3 # DW_AT_name 64 .byte 14 # DW_FORM_strp 65 .byte 16 # DW_AT_stmt_list 66 .byte 23 # DW_FORM_sec_offset 67 .byte 27 # DW_AT_comp_dir 68 .byte 14 # DW_FORM_strp 69 .byte 0 # EOM(1) 70 .byte 0 # EOM(2) 71 .byte 0 # EOM(3) 72 .section .debug_info,"",@progbits 73.Lcu_begin0: 74 .long .Lcu_end0-.Lcu_start0 # Length of Unit 75.Lcu_start0: 76 .short 4 # DWARF version number 77 .long .debug_abbrev # Offset Into Abbrev.
