Subject: [PATCH v2 0/6] fix bitfield initializers
Date: Sat,  8 Apr 2017 23:18:55 +0200	[thread overview]
Message-ID: <20170408211901.40507-1-luc.vanoostenryck@gmail.com> (raw)

The goal of this series is to fix two bugs related
to the initialization of bitfields:
- bad shift & mask
- no implicit zeroing

One notable change is the removal of bit_offset & bit_size
from struct access_data.

Change since v1:
- fix typo in handle_switch_fdump()
- also remove struct access_data:alignment
- also remove struct access_data:origval

This series is available at:
        git://github.com/lucvoo/sparse.git fix-bitfield-init-v2
based on commit:
        14964df5373292af78b29529d4fc7e1a26b67a97 (sparse-next @ 2017-03-31)
up to commit:
	fc981fe285c37ee297e93ef1cc8725caac75f9b3

Luc Van Oostenryck (6):
  add support for a new flag: -fdump-linearize[=only]
  remove bit_size & bit_offset from struct access_data
  add test case for linearize_initializer() of bitfields
  fix implicit zero initializer.
  remove alignment from struct access_data
  remove origval from struct access_data
