Subject: [PATCH v3 0/7] Add --enable-newlib-reent-binary-compat configure option
Date: Mon, 16 May 2022 17:53:22 +0200 [thread overview]
Message-ID: <20220516155329.29458-1-sebastian.huber@embedded-brains.de> (raw)
This patch set adds the --enable-newlib-reent-binary-compat configure option
which may be used to define the new Newlib configuration option
_REENT_BACKWARD_BINARY_COMPAT. This option is used to provide binary backward
compatibility for struct _reent by preserving unused members in struct _reent
to keep the structure layout. Make _REENT_GLOBAL_ATEXIT the default and remove
this option.
v2:
* Rename --enable-newlib-backward-binary-compat in --enable-newlib-reent-binary-compat.
* Do not enable option for Cygwin.
* Adjust code in libgloss.
v3:
* Enable struct _reent backward binary compatibility for Cygwin.
* Rename unused struct _reent members in _reserved_*.
Sebastian Huber (7):
Add --enable-newlib-reent-binary-compat
Cygwin: Enable backward binary compatibility
Optional struct _reent::__unused_sdidinit
Optional struct _reent::_unspecified_locale_info
Optional struct _reent::_new::_reent::_unused_rand
Optional struct _reent::_new::_unused
Use global atexit data for all configurations
