# assembly 2^26 or so times.
#
# We build something which should be laid out as such:
#
# bar.Bar
# main.Func1
# bar.Bar+400-tramp0
# main.BigAsm
# main.Func2
# bar.Bar+400-tramp1
#
# bar.Bar needs to be placed far enough away to generate relocations
# from main package calls. and main.Func1 and main.Func2 are placed

=== Create the configuration file

Travis CI requires you to check in a https://docs.travis-ci.com/user/customizing-the-build/[configuration file] with your source code named `.travis.yml`.
This file contains all relevant instructions for building the project.

The trace test programs in the `testprog` directory generate traces to
stdout.
Otherwise they're just normal programs.

## Trace debug commands

The `cmd` directory contains helpful tools for debugging traces.

* `gotraceraw` parses traces without validation.
  It can produce a text version of the trace wire format, or convert
  the text format back into bytes.
* `gotracevalidate` parses traces and validates them.

 *  * [onHeaders] (unless canceled)
 *  * [onData] (optional sequence of data frames)
 *
 * As a stream ID is scoped to a single HTTP/2 connection, implementations which target multiple
 * connections should expect repetition of stream IDs.
 *
 * Return true to request cancellation of a pushed stream.  Note that this does not guarantee
 * future frames won't arrive on the stream ID.

Otherwise the traces may not be reported.
