This patch commit 27a89f84c458ae938bc3eb92ad0d594c06fc3b42 Author: Thomas Schwinge Date: Fri Feb 17 23:36:20 2023 +0100 '#include "tm_p.h"' in 'gcc/rust/backend/rust-tree.cc' broke rust bootstrap on SPARC: In file included from ./tm_p.h:4, from /vol/gcc/src/hg/master/local/gcc/rust/backend/rust-tree.cc:38: /vol/gcc/src/hg/master/local/gcc/config/sparc/sparc-protos.h:46:47: error: use of enum 'memmodel' without previous declaration 46 | extern void sparc_emit_membar_for_model (enum memmodel, int, int); | ^~~~~~~~ Fixed by including memmodel.h. Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11. Ok for trunk? I'd usually commit the patch as obvious, but have no idea how rust patches are handled.
