* section.c (struct sec): Rename "_cooked_size" to "size". Rename "_raw_size" to "rawsize". (STD_SECTION): Adjust comments. (bfd_set_section_size, bfd_get_section_contents): Use size. (bfd_malloc_and_get_section): New function. * bfd-in.h (bfd_section_size, bfd_get_section_size): Use size. * coff-sh.c (sh_relax_section): Alloc coff_section_data struct early. Correctly free reloc and contents memory. * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME and fake CIE now that we can shink section size to zero. (_bfd_elf_write_section_eh_frame): Likewise.. * elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents. * elf-m10300.c (mn10300_elf_final_link_relocate): Don't use _bfd_stab_section_offset. Use _bfd_elf_section_offset. * stabs.c (_bfd_stab_section_offset_): Remove unused args and unneeded indirection. * elf.c (_bfd_elf_section_offset): .. and update call. * libbfd-in.h (_bfd_stab_section_offset): Update prototype. * libbfd.h: Regenerate. * bfd-in2.h: Regenerate. Replace occurrences of "_raw_size" and "_cooked_size" in most places with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE sections. Use "rawsize", if non-zero, for bfd_get_section_contents calls if the section might be a stabs, eh_frame, or SEC_MERGE section. Similarly use "rawsize", if non-zero, in reloc functions to validate reloc addresses. Use new bfd_malloc_and_get_section in most places where bfd_get_section_contents was called. Expand all occurrences of bfd_section_size and bfd_get_section_size. Rename "raw_size" var in grok_prstatus and similar functions to "size". * aix386-core.c (aix386_core_file_p): .. * aix5ppc-core.c (xcoff64_core_p): .. * aout-adobe.c (aout_adobe_callback,

/* The 68HC12 microcontroler has a memory bank switching system
|
||
with a 16Kb window in the 64Kb address space. The extended memory
|
||
is mapped in the 16Kb window (at 0x8000). The page register controls
|
||
which 16Kb bank is mapped. The call/rtc instructions take care of
|
||
bank switching in function calls/returns.
|
||
|
||
For GNU Binutils to work, we consider there is a physical memory
|
||
at 0..0x0ffff and a kind of virtual memory above that. Symbols
|
||
in virtual memory have their addresses treated in a special way
|
||
when disassembling and when linking.
|
||
|
||
For the linker to work properly, we must always relocate the virtual
|
||
memory as if it is mapped at 0x8000. When a 16-bit relocation is
|
||
made in the virtual memory, we check that it does not cross the
|
||
memory bank where it is used. This would involve a page change
|
||
which would be wrong. The 24-bit relocation is for that and it
|
||
treats the address as a physical address + page number.
