[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

[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

The original commit (7ff0ace96db9164dcde232c36cab6519ea4fce8) was causing build failure and was reverted in 6d242a73264ef1e3e128547f00e0fe2d20d3ada0 ==================== Original Commit Message ==================== This patch adds support for referencing different abbrev tables. We use 'ID' to distinguish abbrev tables and use 'AbbrevTableID' to explicitly assign an abbrev table to compilation units.

Fix debug_abbrev emitter to only assign table id once While generating yamls for my tests I noticed that the new debug_abbrev format (with multiple table support) was incorrectly assigning id's to the table because it was generating one per abbrev entry in the table. For instance, the first table would get id 4 when 5 abbrev entries existed in the table. By itself this is not a problem but the corresponding debug_info sections were still referencing id 0. This was introduced here: https://reviews.llvm.org/D83116. Maybe a better fix is to actually correctly calculate the table id when emitting debug info? From a quick glance it seems to me the ID is just being calculated as the distance between the first DWARFAbbreviationDeclarationSet and the one the debug info entry points to, which means it's just its index and not the actual table id that was generated when emitting the debug_abbrev tables. With my fix I guess this is fine but on the diff that introduced this Pavel mentioned that he would like to have some sort of unique id between them but not necessarily +1 increasing, but for that to work we need to actually find the table ID, I guess by going directly to Y.DebugAbbrev but to honest I have no idea how to link the DWARFAbbreviationDeclarationSet and the Y.DebugAbbrev, so I just did this simple fix. I also realized there's barely any tests for MachO so it might useful to invest on that if the tool is being reworked on.

Fix debug_abbrev emitter to only assign table id once While generating yamls for my tests I noticed that the new debug_abbrev format (with multiple table support) was incorrectly assigning id's to the table because it was generating one per abbrev entry in the table. For instance, the first table would get id 4 when 5 abbrev entries existed in the table. By itself this is not a problem but the corresponding debug_info sections were still referencing id 0. This was introduced here: https://reviews.llvm.org/D83116. Maybe a better fix is to actually correctly calculate the table id when emitting debug info? From a quick glance it seems to me the ID is just being calculated as the distance between the first DWARFAbbreviationDeclarationSet and the one the debug info entry points to, which means it's just its index and not the actual table id that was generated when emitting the debug_abbrev tables. With my fix I guess this is fine but on the diff that introduced this Pavel mentioned that he would like to have some sort of unique id between them but not necessarily +1 increasing, but for that to work we need to actually find the table ID, I guess by going directly to Y.DebugAbbrev but to honest I have no idea how to link the DWARFAbbreviationDeclarationSet and the Y.DebugAbbrev, so I just did this simple fix. I also realized there's barely any tests for MachO so it might useful to invest on that if the tool is being reworked on.
