ae0fbfb1fb [XRay] A tool for Comparing xray function call graphs
Summary:
This is a tool for comparing the function graphs produced by the
llvm-xray graph too. It takes the form of a new subcommand of the
llvm-xray tool 'graph-diff'.

This initial version of the patch is very rough, but it is close to
feature complete.

Summary:
In Preparation for graph comparison, this patch breaks out the color
choice code from xray-graph into a library and adds polynomials for
the Sequential and Difference sets from ColorBrewer.

061ca191c0 [XRay] Implement the llvm-xray graph subcommand
Here we define the `graph` subcommand which generates a graph from the function
call information and uses it to present the call information graphically with
additional annotations.

c4416a6dc0 [XRay] Implement the llvm-xray account subcommand
Summary:
This is the third of a multi-part change to implement subcommands for
the `llvm-xray` tool.

Here we define the `account` subcommand which does simple function call
accounting, generating basic statistics on function calls we find in an
XRay log/trace. We support text output and csv output for this
subcommand.

This change also supports sorting, summing, and filtering the top N
results.

Part of this tool will later be turned into a library that could be used
for basic function call accounting.

Depends on D24376.

14cdbca6b8 [XRay] Define the library for XRay trace logs
Summary:
In this change we move the definition of the log reading routines from
the tools directory in LLVM to {include/llvm,lib}/XRay. We improve the
documentation a little bit for the publicly accessible headers, and
adjust the top-matter. This also leads to some refactoring and cleanup
in the tooling code.

In particular, we do the following:

  - Rename the class from LogReader to Trace, as it better represents
    the logical set of records as opposed to a log.
  - Use file type detection instead of asking the user to say what
    format the input file is. This allows us to keep the interface
    simple and encapsulate the logic of loading the data appropriately.

In future changes we increase the API surface and write dedicated unit
tests for the XRay library.

Depends on D24376.

6e1f066adf [XRay] Implement llvm-xray convert -- trace file conversion
This is the second part of a multi-part change to define additional
subcommands to the `llvm-xray` tool.

This change defines a conversion subcommand to take XRay log files, and
turns them from one format to another (binary or YAML). This currently
only supports the first version of the log file format, defined in the
compiler-rt runtime.

Depends on D21987.

5a35548822 [XRay] Implement llvm-xray extract, start of the llvm-xray tool
Usage:

  llvm-xray extract <object file> [-o <filename or '-'>]

The tool gets the XRay instrumentation map from an object file and turns
it into YAML.  We first support ELF64 sleds on x86_64 binaries, with
provision for supporting other supported platforms and formats later.

This is the first of a many-part change to fully implement the
`llvm-xray` tool.

We also define a subcommand registration and dispatch mechanism to be
used by other further subcommand implementations for llvm-xray.
