# This file is sourced from elf32.em, and defines extra m68hc12-elf
# and m68hc11-elf specific routines.  It is used to generate the
# HC11/HC12 trampolines to call a far function by using a normal 'jsr/bsr'.
#
# - The HC11/HC12 relocations are checked to see if there is a
#   R_M68HC11_16 relocation to a symbol marked with STO_M68HC12_FAR.
#   This relocation cannot be made on the symbol but must be made on
#   its trampoline
#   The trampolines to generate are collected during this pass
#   (See elf32_m68hc11_size_stubs)
#
# - The trampolines are generated in a ".tramp" section.  The generation
#   takes care of HC11 and HC12 specificities.
#   (See elf32_m68hc11_build_stubs)
#
# - During relocation the R_M68HC11_16 relocation to the far symbols
#   are redirected to the trampoline that was generated.
#
# Copied from hppaelf and adapted for M68HC11/M68HC12 specific needs.
