Subject: [PATCH 0/6] Add --enable-newlib-reent-binary-compat configure option
Date: Mon, 16 May 2022 08:55:51 +0200 [thread overview]
Message-ID: <20220516065557.78164-1-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.
Sebastian Huber (6):
Add --enable-newlib-reent-binary-compat
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
