Leverage cacheTextUpdate for __clear_cache on VxWorks
2018-09-21 Alexandre Oliva <oliva@adacore.com>
libgcc/
* config/vxcache.c: New file. Provide __clear_cache, based on
the cacheTextUpdate VxWorks service.
* config/t-vxworks (LIB2ADD): Add vxcache.c.
(LIB2FUNCS_EXCLUDE): Add _clear_cache.
* config/t-vxwoks7: Likewise.
gcc/
* config/vxworks.h (CLEAR_INSN_CACHE): #define to 1.
