Subject: [PATCH v2 0/7] Delete unused methods in EWAH bitmap
Date: Fri, 15 Jun 2018 18:27:36 +0000	[thread overview]
Message-ID: <20180615182727.172075-1-dstolee@microsoft.com> (raw)
In-Reply-To: <20180615143018.170686-1-dstolee@microsoft.com>

The EWAH bitmap code includes several logical operations that are
important for a general-purpose bitmap library. However, Git only
uses the XOR operation for storing deltas between reachability
bitmaps. This means that we can delete the following unused methods:

* ewah_and()
* ewah_and_not()
* ewah_not()
* ewah_or()
* ewah_serialize()

We can also delete the unused methods bitmap_clear() and
bitmap_each_bit().

Derrick Stolee (7):
  ewah/bitmap.c: delete unused 'bitmap_clear()'
  ewah/bitmap.c: delete unused 'bitmap_each_bit()'
  ewah_bitmap: delete unused 'ewah_and()'
  ewah_bitmap: delete unused 'ewah_and_not()'
  ewah_bitmap: delete unused 'ewah_not()'
  ewah_bitmap: delete unused 'ewah_or()'
  ewah_io: delete unused 'ewah_serialize()'
