Subject: [RFC v2 09/12] kunit: mock: add macro machinery to pick correct format args
Date: Mon, 12 Oct 2020 15:20:47 -0700	[thread overview]
Message-ID: <20201012222050.999431-10-dlatypov@google.com> (raw)
In-Reply-To: <20201012222050.999431-1-dlatypov@google.com>

From: Marcelo Schmitt <marcelo.schmitt1@gmail.com>

Note: It was unclear if there was existing code that could be reused.

This is used by DEFINE_MATCHER to generate matching funcs for primitive
types that don't trigger compiler warnings.

After preprocessing, we now generate matcher func code like
  kunit_stream_add(stream, "%p not > "%p", actual, matcher->expected)
as opposed to the hoping %d will work for all types.
