[DWARFYAML][debug_info] Replace 'InitialLength' with 'Format' and 'Length'. 'InitialLength' is replaced with 'Format' (DWARF32 by default) and 'Length' in this patch. Besides, test cases for DWARFv4 and DWARFv5, DWARF32 and DWARF64 is added. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D82622

## This file contains test cases for generating a DAWRFv4 .debug_info
## section in object files from the DWARF entry of Mach-O YAML inputs.
## a) Test that yaml2obj emits a DWARF32 .debug_info sections and obj2yaml
## converts it back.
# RUN: yaml2obj --docnum=1 %s | obj2yaml | FileCheck %s --check-prefix=DWARF32
[ObjectYAML] Support for DWARF debug_info section This patch adds support for YAML<->DWARF for debug_info sections. This re-lands r290147, reverted in 290148, re-landed in r290204 after fixing the issue that caused bots to fail (thank you UBSan!), and reverted again in r290209 due to failures on big endian systems. After adding support for preserving endianness, this should be good now. llvm-svn: 290386

[DWARFYAML][debug_aranges] Replace InitialLength with Format and Length. This patch addresses the comment in [D80972](https://reviews.llvm.org/D80972#inline-744217). Before this patch, the initial length field of .debug_aranges section should be declared as: ``` ## 32-bit DWARF debug_aranges: - Length: TotalLength: 0x20 Version: 2 ... ## 64-bit DWARF debug_aranges: - Length: TotalLength: 0xffffffff TotalLength64: 0x20 Version: 2 ... ``` After this patch: ``` ## 32-bit DWARF debug_aranges: - [[Format: DWARF32]] ## Optional Length: 0x20 Version: 2 ... ## 64-bit DWARF debug_aranges: - Format: DWARF64 Length: 0x20 Version: 2 ``` Current implementation of generating DWARF64 .debug_aranges section is buggy. A follow-up patch will improve it and add test cases for DWARF64. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D81063

[ObjectYAML] Support for DWARF line tables One more try... relanding r291541 with a fix to properly gate MaxOpsPerInst on DWARF version. Description from r291541: This patch re-lands r291470, which failed on Linux bots. The issue (I believe) was undefined behavior because the size of llvm::dwarf::LineNumberOps was not explcitly specified or consistently respected. The updated patch adds an explcit underlying type to the enum and preserves the size more correctly. Original description: This patch adds support for the DWARF debug_lines section. The line table state machine opcodes are preserved, so this can be used to test the state machine evaluation directly. llvm-svn: 291546

[ObjectYAML] Support for DWARF debug_info section This patch adds support for YAML<->DWARF for debug_info sections. This re-lands r290147, reverted in 290148, re-landed in r290204 after fixing the issue that caused bots to fail (thank you UBSan!), and reverted again in r290209 due to failures on big endian systems. After adding support for preserving endianness, this should be good now. llvm-svn: 290386

[DWARFYAML][debug_info] Replace 'InitialLength' with 'Format' and 'Length'. 'InitialLength' is replaced with 'Format' (DWARF32 by default) and 'Length' in this patch. Besides, test cases for DWARFv4 and DWARFv5, DWARF32 and DWARF64 is added. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D82622
