Cleanup LLVMDWARFDebugInfo

2022-02-15T08:16:03+00:00

As usual with that header cleanup series, some implicit dependencies now need to
be explicit:

llvm/DebugInfo/DWARF/DWARFContext.h no longer includes:
- "llvm/DebugInfo/DWARF/DWARFAcceleratorTable.h"
- "llvm/DebugInfo/DWARF/DWARFCompileUnit.h"
- "llvm/DebugInfo/DWARF/DWARFDebugAbbrev.h"
- "llvm/DebugInfo/DWARF/DWARFDebugAranges.h"
- "llvm/DebugInfo/DWARF/DWARFDebugFrame.h"
- "llvm/DebugInfo/DWARF/DWARFDebugLoc.h"
- "llvm/DebugInfo/DWARF/DWARFDebugMacro.h"
- "llvm/DebugInfo/DWARF/DWARFGdbIndex.h"
- "llvm/DebugInfo/DWARF/DWARFSection.h"
- "llvm/DebugInfo/DWARF/DWARFTypeUnit.h"
- "llvm/DebugInfo/DWARF/DWARFUnitIndex.h"

Plus llvm/Support/Errc.h not included by a bunch of llvm/DebugInfo/DWARF/DWARF*.h files

Preprocessed lines to build llvm on my setup:
after: 1065629059
before: 1066621848

Which is a great diff!

[DWARF][NFC] add ParentIdx and SiblingIdx to DWARFDebugInfoEntry for faster navigation.

2021-10-02T05:11:06+00:00

This patch implements suggestion done while reviewing D102634. It adds two fields:
ParentIdx and SiblingIdx. These fields allow fast navigation to die parent and
die sibling. These fields are set at the moment when dies are loaded.

dsymutil works 2% faster with this patch(run on clang binary).

[DWARF] Remove extractFast (NFC)

2021-08-11T16:55:00+00:00

The last use was removed on Dec 13, 2016 in commit
c8c1032c0c52d7f851ccfa29ec850b24047ebcb9.  This patch repurposes the
function comment for the other variant of extractFast.

llvm-dwarfdump: Print warnings on invalid DWARF

2021-06-27T09:38:35+00:00

llvm-dwarfdump was silent even when the format of DWARF was invalid
and/or llvm-dwarfdump did not understand/support some of the constructs.
This can be pretty confusing as llvm-dwarfdump is a tool for DWARF
producers+consumers development.

[llvm-dwarfdump] Avoid crashing if an abbreviation offset is invalid.

2020-08-12T09:01:53+00:00

Note that DWARFUnit::getAbbreviations() returns nullptr if the
abbreviations could not be read, but callers used the returned
pointer without checking.

Switch LLVM to use 64-bit offsets (2/5)

This updates all libraries and tools in LLVM Core to use 64-bit offsets
which directly or indirectly come to DataExtractor.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[DWARF] NFC: DWARFDataExtractor combines relocs with DataExtractor.

2017-06-29T16:52:08+00:00

Requires callers to directly associate relocations with a DataExtractor
used to read data from a DWARF section, which helps a callee not make
assumptions about which section it is reading.
This is the next step in reducing DWARFFormValue's dependence on DWARFUnit.
