Synopsis
|
|
--------
|
|
|
|
:program:`llvm-pdbutil` [*subcommand*] [*options*]
|
|
|
|
Description
|
|
-----------
|
|
|
|
Display types, symbols, CodeView records, and other information from a
|
|
PDB file, as well as manipulate and create PDB files. :program:`llvm-pdbutil`
|
|
is normally used by FileCheck-based tests to test LLVM's PDB reading and
|
|
writing functionality, but can also be used for general PDB file investigation
|
|
and forensics, or as a replacement for cvdump.
|
|
|
|
Subcommands
|
|
-----------
|
|
|
|
:program:`llvm-pdbutil` is separated into several subcommands each tailored to
|
|
a different purpose. A brief summary of each command follows, with more detail
|
|
in the sections that follow.
|
|
|
|
* :ref:`pretty_subcommand` - Dump symbol and type information in a format that
|
|
tries to look as much like the original source code as possible.
|
|
* :ref:`dump_subcommand` - Dump low level types and structures from the PDB
|
|
file, including CodeView records, hash tables, PDB streams, etc.
|
|
* :ref:`bytes_subcommand` - Dump data from the PDB file's streams, records,
|
|
types, symbols, etc as raw bytes.
|
|
* :ref:`yaml2pdb_subcommand` - Given a yaml description of a PDB file, produce
|
|
a valid PDB file that matches that description.
|
|
* :ref:`pdb2yaml_subcommand` - For a given PDB file, produce a YAML
|
|
description of some or all of the file in a way that the PDB can be
|
|
reconstructed.
|
|
* :ref:`merge_subcommand` - Given two PDBs, produce a third PDB that is the
|
|
result of merging the two input PDBs.

.. program:: llvm-pdbutil pretty
|
|
|
|
.. important::
|
|
The **pretty** subcommand is built on the Windows DIA SDK, and as such is not
|
|
supported on non-Windows platforms.
|
|
|
|
USAGE: :program:`llvm-pdbutil` pretty [*options*] <input PDB file>
|
|
|
|
Summary
|
|
^^^^^^^^^^^
|
|
|
|
The *pretty* subcommand displays a very high level representation of your
|
|
program's debug info. Since it is built on the Windows DIA SDK which is the
|
|
standard API that Windows tools and debuggers query debug information, it
|
|
presents a more authoritative view of how a debugger is going to interpret your
|
|
debug information than a mode which displays low-level CodeView records.

Summary
|
|
^^^^^^^^^^^
|
|
|
|
The **dump** subcommand displays low level information about the structure of a
|
|
PDB file. It is used heavily by LLVM's testing infrastructure, but can also be
|
|
used for PDB forensics. It serves a role similar to that of Microsoft's
|
|
`cvdump` tool.
|
|
|
|
.. note::
|
|
The **dump** subcommand exposes internal details of the file format. As
|
|
such, the reader should be familiar with :doc:`/PDB/index` before using this
|
|
command.
|
|

|
dumps the entire dependency graph for the specified index instead of just the
|
|
single record with the specified index. For example, if type index 0x4000 is
|
|
a function whose return type has index 0x3000, and you specify
|
|
`-dependents=0x4000`, then this would dump both records (as well as any other

|
Summary
|
|
^^^^^^^
|
|
|
|
Like the **dump** subcommand, the **bytes** subcommand displays low level
|
|
information about the structure of a PDB file, but it is used for even deeper
|
|
forensics. The **bytes** subcommand finds various structures in a PDB file
|
|
based on the command line options specified, and dumps them in hex. Someone
|
|
working on support for emitting PDBs would use this heavily, for example, to
|
|
compare one PDB against another PDB to ensure byte-for-byte compatibility. It
|
|
is not enough to simply compare the bytes of an entire file, or an entire stream
|
|
because it's perfectly fine for the same structure to exist at different
|
|
locations in two different PDBs, and "finding" the structure is half the battle.
|
