+ * config.m4.in (SYMBOL_PREFIX): Define from from autoconf
+ ASM_SYMBOL_PREFIX.
+ (C_NAMS): move definition to...
+ * asm.m4 (C_NAME): Define here, also take fat_transform.
+ (fat_suffix): Replaced by...
+ (fat_transform): New macro, taking symbol nama as argument.
+ Updated all uses of fat_suffix.
+ * fat-x86_64.c: Updated for internal "_nettle" prefix on
+ cpu-specific memxor functions.
+
* fat-x86_64.c: Set up for sse2 vs non-sse2 memxor. Patch by Nikos
Mavrogiannopoulos.
* configure.ac (asm_nettle_optional_list): Added memxor-2.asm.
