Subject: [PATCH 0/7] Add --enable-newlib-backward-binary-compat configure option
Date: Fri, 13 May 2022 15:46:53 +0200	[thread overview]
Message-ID: <20220513134700.68563-1-sebastian.huber@embedded-brains.de> (raw)

This patch set adds the --enable-newlib-backward-binary-compat configure option
which may be used to define the new Newlib configuration option
_NEWLIB_BACKWARD_BINARY_COMPAT.  This option can be used to provided binary
backward compatibility, for example by preserving unused members in struct
_reent to keep the structure layout.  Make _REENT_GLOBAL_ATEXIT the default and
remove this option.

Sebastian Huber (7):
  Add --enable-newlib-backward-binary-compat
  Cygwin: Enable backward binary compatibility
  Optional struct _reent::__unused_sdidinit
  Optional struct _reent::_unspecified_locale_info
  Optional struct _reent::_new::_unused
  Optional struct _reent::_new::_reent::_unused_rand
  Use global atexit data for all configurations
