Subject: (print_operand): 'x' and 'y' mode letters only if SUPPORT_SUN_FPA.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f4a6e73be91dc7caa9f74b017640612ea6bf2cb8;p=gcc.git

(print_operand): 'x' and 'y' mode letters only if SUPPORT_SUN_FPA.

(print_operand_address): If (new) ASM_OUTPUT_CASE_FETCH defined, use it to
emit the address for the insn before a tablejump.

    define such "LDnnn" to be either "Lnnn-LInnn-2.b", "Lnnn", or any other

    macro.  See m68k/sgs.h for an example; for versions without the bug.

    They also do not like things like "pea 1.w", so we simple leave off
    the .w on small constants.
