Be lazy converting markers to integers, bytecode_{arithcompare,arithop}(). src/ChangeLog addition: 2013-12-15 Aidan Kehoe <kehoea@parhasard.net> * bytecode.c (bytecode_arithcompare): * bytecode.c (bytecode_arithop): Call promote_args_lazy () in these two functions, only converting markers to fixnums if absolutely necessary (since that is ON with large, mule buffers). * data.c (BIGNUM_CASE): * data.c (RATIO_CASE): * data.c (BIGFLOAT_CASE): * data.c (ARITHCOMPARE_MANY): Call promote_args_lazy () here too if WITH_NUMBER_TYPES is defined. We're not doing the equivalent with the non-NUMBER_TYPES code, but that's mostly fine, we are doing it in the bytecode. * number.h: * number.h (NUMBER_TYPES): * number.h (promote_args_lazy): Add this, returning LAZY_MARKER_T if both arguments are markers that point to the same buffer. tests/ChangeLog addition: 2013-12-15 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Test arithmetic comparisons with markers, check the type of the returned values for #'min and #'max.
