* 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,

set PRIV(buf_size) and return it
|

|
||
this is a little tricky since it should be portable.
|
||
|
||
the openVMS object file has 'variable length' which means that
|
||
read() returns data in chunks of (hopefully) correct and expected
|
||
size. The linker (and other tools on vms) depend on that. Unix doesn't
|
||
know about 'formatted' files, so reading and writing such an object
|
||
file in a unix environment is not trivial.
|
||
|
||
With the tool 'file' (available on all vms ftp sites), one
|
||
can view and change the attributes of a file. Changing from
|
||
'variable length' to 'fixed length, 512 bytes' reveals the
|
||
record length at the first 2 bytes of every record. The same
|
||
happens during the transfer of object files from vms to unix,
|
||
at least with ucx, dec's implementation of tcp/ip.
|
||
|
||
The vms format repeats the length at bytes 2 & 3 of every record.
|
||
|
||
On the first call (file_format == FF_UNKNOWN) we check if
|
||
the first and the third byte pair (!) of the record match.
|
||
If they do it's an object file in an unix environment or with
|
||
wrong attributes (FF_FOREIGN), else we should be in a vms
|
||
environment where read() returns the record size (FF_NATIVE).
|
||
|
||
reading is always done in 2 steps.
|
||
first just the record header is read and the length extracted
|
||
by get_header_values
|
||
then the read buffer is adjusted and the remaining bytes are
|
||
read in.
