v0.0.0-6067-g6a0464959

Fix typo in butterfly topology documentation.

Change "-tree" to "-fly" when needed and change "-" to "\-" to correctly render the italics.

v0.0.0-6045-gd0c9bbd4d

Make codegen implement shra as a function.

This allows us to bind the intermediate result `$signed(to_shift) >>> amount` to a reg with a defined width, which avoids the `$signed()` having a self-determined width, which is a lint finding.

Fixes google/xls#1642.

v0.0.0-5955-ge5bcb56fb

Tell clang-tidy explicitly to consider code c++20.

Even though the -std=c++20 makes it into the
compilation DB, clang-tidy does not pick it up.

So be explicit and add it to the --extra-args on
invocation.

Thie fixes all reported [clang-diagnostic-error] that
were due to clang-tidy not recognizing c++20 constructs
and also some misc-include-cleaner warnings in which it
previously flagged some includes because it was tripping
over some other problem in the file in question.

v0.0.0-5947-gc4c12c46e

Simplify clang-tidy and explicitly list all relevant rules.

Without using wild-card options, it is easier to switch between
clang-tidy versions without getting new, unexpected findings.

This selective approach also reports less than the previous
configuration which was mostly enabling everything, then only
disabling the rules that were not helpful. Now, we're just
enabling vetted helpful rules.

Output of `xls/dev_tools/run-clang-tidy-cached.sh` is
now a more manageable
