I added this macro in 2011 to fix some signedness comparison bugs. However, it’s a weird macro and the bugs can be fixed in a more-straightforward way. This helps performance slightly (0.5%) on my platform (Fedora 31 x86-64, GCC 9.3.1 with -O2). * src/casefiddle.c (do_casify_natnum): Use simple comparison instead of UNSIGNED_CMP. * src/character.h (CHAR_VALID_P, SINGLE_BYTE_CHAR_P, CHAR_STRING): * src/composite.h (COMPOSITION_ENCODE_RULE_VALID): * src/lisp.h (ASCII_CHAR_P): Now an inline function, and uses simple comparison instead of UNSIGNED_CMP. * src/dispextern.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL) (IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): Move these to ... * src/frame.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL) (IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): ... here, and make them inline functions that no longer use UNSIGNED_CMP. * src/keyboard.c (read_char): UNSIGNED_CMP is not needed here since XFIXNAT always returns a nonnegative value. * src/lisp.h (UNSIGNED_CMP): Remove; no longer used.
