From 94c2e85bea1ab1b837a4c055ccc83d5cd32dd027 Mon Sep 17 00:00:00 2001 From: Kevin Enderby Date: Fri, 9 Dec 2011 18:09:40 +0000 Subject: The second part of support for generating dwarf for assembly source files. This generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each non-temporary label. The next part will be to get the clang driver to enable this when assembling a .s file. rdar://9275556 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146262 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/MC/MachO/gen-dwarf.s | 113 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 113 insertions(+) create mode 100644 test/MC/MachO/gen-dwarf.s (limited to 'test') diff --git a/test/MC/MachO/gen-dwarf.s b/test/MC/MachO/gen-dwarf.s new file mode 100644 index 0000000000..6b851354cc --- /dev/null +++ b/test/MC/MachO/gen-dwarf.s @@ -0,0 +1,113 @@ +// RUN: llvm-mc -g -triple i386-apple-darwin10 %s -filetype=obj -o %t +// RUN: llvm-dwarfdump %t | FileCheck %s + +.globl _bar +_bar: + movl $0, %eax +L1: leave + ret +_foo: + nop +.data +_x: .long 1 + +// CHECK: file format Mach-O 32-bit i386 + +// CHECK: .debug_abbrev contents: +// CHECK: Abbrev table for offset: 0x00000000 +// CHECK: [1] DW_TAG_compile_unit DW_CHILDREN_yes +// CHECK: DW_AT_stmt_list DW_FORM_data4 +// CHECK: DW_AT_low_pc DW_FORM_addr +// CHECK: DW_AT_high_pc DW_FORM_addr +// CHECK: DW_AT_name DW_FORM_string +// CHECK: DW_AT_comp_dir DW_FORM_string +// CHECK: DW_AT_producer DW_FORM_string +// CHECK: DW_AT_language DW_FORM_data2 + +// CHECK: [2] DW_TAG_subprogram DW_CHILDREN_yes +// CHECK: DW_AT_name DW_FORM_string +// CHECK: DW_AT_decl_file DW_FORM_data4 +// CHECK: DW_AT_decl_line DW_FORM_data4 +// CHECK: DW_AT_low_pc DW_FORM_addr +// CHECK: DW_AT_high_pc DW_FORM_addr +// CHECK: DW_AT_prototyped DW_FORM_flag + +// CHECK: [3] DW_TAG_unspecified_parameters DW_CHILDREN_no + + +// CHECK: .debug_info contents: + +// We don't check the leading addresses these are at. +// CHECK: DW_TAG_compile_unit [1] * +// CHECK: DW_AT_stmt_list [DW_FORM_data4] (0x00000000) +// CHECK: DW_AT_low_pc [DW_FORM_addr] (0x0000000000000000) +// CHECK: DW_AT_high_pc [DW_FORM_addr] (0x0000000000000008) +// We don't check the file name as it is a temp directory +// CHECK: DW_AT_name [DW_FORM_string] +// We don't check the DW_AT_comp_dir which is the current working directory +// CHECK: DW_AT_producer [DW_FORM_string] ("llvm-mc (based on LLVM 3.1svn)") +// CHECK: DW_AT_language [DW_FORM_data2] (0x8001) + +// CHECK: DW_TAG_subprogram [2] * +// CHECK: DW_AT_name [DW_FORM_string] ("bar") +// CHECK: DW_AT_decl_file [DW_FORM_data4] (0x00000001) +// CHECK: DW_AT_decl_line [DW_FORM_data4] (0x00000005) +// CHECK: DW_AT_low_pc [DW_FORM_addr] (0x0000000000000000) +// CHECK: DW_AT_high_pc [DW_FORM_addr] (0x0000000000000007) +// CHECK: DW_AT_prototyped [DW_FORM_flag] (0x00) + +// CHECK: DW_TAG_unspecified_parameters [3] + +// CHECK: NULL + +// CHECK: DW_TAG_subprogram [2] * +// CHECK: DW_AT_name [DW_FORM_string] ("foo") +// CHECK: DW_AT_decl_file [DW_FORM_data4] (0x00000001) +// CHECK: DW_AT_decl_line [DW_FORM_data4] (0x00000009) +// CHECK: DW_AT_low_pc [DW_FORM_addr] (0x0000000000000007) +// CHECK: DW_AT_high_pc [DW_FORM_addr] (0x0000000000000008) +// CHECK: DW_AT_prototyped [DW_FORM_flag] (0x00) + +// CHECK: DW_TAG_unspecified_parameters [3] + +// CHECK: NULL + +// CHECK: NULL + +// CHECK: .debug_aranges contents: +// CHECK: Address Range Header: length = 0x0000001c, version = 0x0002, cu_offset = 0x00000000, addr_size = 0x04, seg_size = 0x00 + +// CHECK: .debug_lines contents: +// CHECK: Line table prologue: +// We don't check the total_length as it includes lengths of temp paths +// CHECK: version: 2 +// We don't check the prologue_length as it too includes lengths of temp paths +// CHECK: min_inst_length: 1 +// CHECK: default_is_stmt: 1 +// CHECK: line_base: -5 +// CHECK: line_range: 14 +// CHECK: opcode_base: 13 +// CHECK: standard_opcode_lengths[DW_LNS_copy] = 0 +// CHECK: standard_opcode_lengths[DW_LNS_advance_pc] = 1 +// CHECK: standard_opcode_lengths[DW_LNS_advance_line] = 1 +// CHECK: standard_opcode_lengths[DW_LNS_set_file] = 1 +// CHECK: standard_opcode_lengths[DW_LNS_set_column] = 1 +// CHECK: standard_opcode_lengths[DW_LNS_negate_stmt] = 0 +// CHECK: standard_opcode_lengths[DW_LNS_set_basic_block] = 0 +// CHECK: standard_opcode_lengths[DW_LNS_const_add_pc] = 0 +// CHECK: standard_opcode_lengths[DW_LNS_fixed_advance_pc] = 1 +// CHECK: standard_opcode_lengths[DW_LNS_set_prologue_end] = 0 +// CHECK: standard_opcode_lengths[DW_LNS_set_epilogue_begin] = 0 +// CHECK: standard_opcode_lengths[DW_LNS_set_isa] = 1 +// We don't check include_directories as it has a temp path +// CHECK: Dir Mod Time File Len File Name +// CHECK: ---- ---------- ---------- --------------------------- +// CHECK: file_names[ 1] 1 0x00000000 0x00000000 gen-dwarf.s + +// CHECK: Address Line Column File ISA Flags +// CHECK: ------------------ ------ ------ ------ --- ------------- +// CHECK: 0x0000000000000000 6 0 1 0 is_stmt +// CHECK: 0x0000000000000005 7 0 1 0 is_stmt +// CHECK: 0x0000000000000006 8 0 1 0 is_stmt +// CHECK: 0x0000000000000007 10 0 1 0 is_stmt +// CHECK: 0x0000000000000008 10 0 1 0 is_stmt end_sequence -- cgit v1.2.3
