From: Sebastian Huber Date: Mon, 17 Jul 2017 05:27:13 +0000 (+0000) Subject: [SPARC/RTEMS] Add __FIX_LEON3FT_B2BST X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=42ec024baa1bc9de83c8fcefe543f58a6939068d;p=gcc.git [SPARC/RTEMS] Add __FIX_LEON3FT_B2BST In case the LEON3FT back-to-back store workaround is active (sparc_fix_b2bst), then define the builtin define __FIX_LEON3FT_B2BST on RTEMS. The intended use case for this is operating system code in assembly language.
