23 | * config/tc-m68hc11.c (M6811_OP_CALL_ADDR): New internal define. | |
24 | (M6811_OP_PAGE_ADDR): New internal define. | |
25 | (get_operand): New modifier %page and %addr to obtain page and | |
26 | address part of a far-function. | |
27 | (fixup8): Use BFD_RELOC_M68HC11_PAGE for a %page modifier; don't | |
28 | complain on overflow for the BFD_RELOC_M68HC11_PAGE and truncation | |
29 | relocs. | |
30 | (fixup16): Use BFD_RELOC_M68HC11_LO16 for a %addr modifier. | |
31 | (find_opcode): Add comment. | |
32 | (md_estimate_size_before_relax): Force relocation of | |
33 | STATE_UNDEXED_OFFSET types when the symbol is not absolute. | |
34 | (tc_m68hc11_fix_adjustable): Check for BFD_RELOC_M68HC11_LO16 | |
35 | instead of BFD_RELOC_LO16; temporarily make the BFD_RELOC_32 | |
36 | on the symbol itself so that DWARF2 strings are merged correctly. | |
