Alias keyword (#868) Implementation for an "alias" keyword. By now, only applied inside memory descriptions. * Make "mem_alias" a separate nonterminal. The previous implementation attempt caused a syntax error in yacc code, and separating mem_alias on the same level as mem_spec appears to be the cleaner solution anyway. * Maintain real memory aliases. Instead of duplicating the aliased memory with a new name, maintain a second list of memory aliases (per device) that contains a pointer to the memory area it is aliased to. That way, a memory name can be clearly distinguished between the canonical one and any aliases. * Check p->mem_alias != NULL before touching it * Add avr_find_memalias() This takes a memory region as input, and searches whether an alias can be found for it. * We need to add a list structure for the mem_alias list, always. By that means, mem_alias won't ever be NULL, so no need to check later. Also, in avr_dup_part(), duplicate the alias list. * In a memory alias, actually remember the current name. * In avr_dup_part(), adjust pointers of aliased memories While walking the list of memories, for each entry, see if there is an alias pointing to it. If so, allocate a duplicated one, and fix its aliased_mem pointer to point to the duplicated memory region instead of the original one. * Add avr_locate_mem_noalias() When looking whether any memory region has already been defined for the current part while parsing the config file, only non-aliased names must be considered. Otherwise, a newly defined alias would kick out the memory definition it is being aliased to. * When defining a mem_alias, drop any existing one of that name. * Actually use avr_find_memalias() to find aliases * Add declaration for avr_find_memalias() * When defining a memory, also search for an existing alias If the newly defined name has the same as an existing alias, the alias can be removed. Note that we do explicitly *not* remove any memory by the same name of a later defined alias, as this might invalidate another alias'es pointer. If someone defines that, the alias name just won't ever be found by avr_locate_mem().
