There are quite a few configuration macros in the project. As discussed in the #2520 issue there are a few awkward constructs. Main changes: * The following macros are now 0/1 switches: ** Renamed CONFIG_ECMA_LCACHE_DISABLE to JERRY_LCACHE. ** Renamed CONFIG_ECMA_PROPERTY_HASHMAP_DISABLE to JERRY_PROPERTY_HASHMAP. ** Renamed CONFIG_DISABLE_UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION. ** Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE. ** Renamed JERRY_DISABLE_JS_PARSER to JERRY_PARSER. ** Renamed JERRY_ENABLE_ERROR_MESSAGES to JERRY_ERROR_MESSAGES. ** Renamed JERRY_ENABLE_EXTERNAL_CONTEXT to JERRY_EXTERNAL_CONTEXT. ** Renamed JERRY_ENABLE_LINE_INFO to JERRY_LINE_INFO. ** Renamed JERRY_ENABLE_LOGGING to JERRY_LOGGING. ** Renamed JERRY_ENABLE_SNAPSHOT_EXEC to JERRY_SNAPSHOT_EXEC. ** Renamed JERRY_ENABLE_SNAPSHOT_SAVE to JERRY_SNAPSHOT_SAVE. ** Renamed JERRY_SYSTEM_ALLOCATOR to JERRY_SYSTEM_ALLOCATOR. ** Renamed JERRY_VM_EXEC_STOP to JERRY_VM_EXEC_STOP. ** Renamed JMEM_GC_BEFORE_EACH_ALLOC to JERRY_MEM_GC_BEFORE_EACH_ALLOC. ** Renamed JMEM_STATS to JERRY_MEM_STATS. ** Renamed PARSER_DUMP_BYTE_CODE to JERRY_PARSER_DUMP_BYTE_CODE. ** Renamed REGEXP_DUMP_BYTE_CODE to JERRY_REGEXP_DUMP_BYTE_CODE. * Recursion check changes: ** Renamed REGEXP_RECURSION_LIMIT to JERRY_REGEXP_RECURSION_LIMIT. ** Renamed VM_RECURSION_LIMIT to JERRY_VM_RECURSION_LIMIT. * Attribute macro changes: ** Renamed JERRY_CONST_DATA to JERRY_ATTR_CONST_DATA. ** Renamed JERRY_HEAP_SECTION_ATTR to JERRY_ATTR_GLOBAL_HEAP. Now the macro can specify any attribute for the global heap object. * Other macro changes: ** Renamed CONFIG_MEM_HEAP_AREA_SIZE to JERRY_GLOBAL_HEAP_SIZE. Then new macro now specify the global heap size in kilobytes. * Updated documentations to reflect the new macro names. For more deatils please see jerry-core/config.h.
