Major change; changed calling convention for bfd_get_relocated_section_contents so that caller allocates memory for section data. * coffcode.h (bfd_coff_get_relocated_section_contents), reloc.c, seclet.c, targets.c, bfd.c: reflect new convention. * coffcode.h (styp_to_sec_flags): if styp_flags is not a special case, then use reasonable default values for SEC_* flags.

/* bfd.h -- The only header file required by users of the bfd library
|

|
||
This file is generated from various .c files, if you change it, your
|
||
bits may be lost.
|
||
|
||
All the prototypes and definitions following the comment "THE FOLLOWING
|
||
IS EXTRACTED FROM THE SOURCE" are extracted from the source files for
|
||
BFD. If you change it, someone oneday will extract it from the source
|
||
again, and your changes will be lost. To save yourself from this bind,
|
||
change the definitions in the source in the bfd directory. Type "make
|
||
docs" and then "make headers" in that directory, and magically this file
|
||
will change to reflect your changes.
|
||
|
||
If you don't have the tools to perform the extraction, then you are
|
||
safe from someone on your system trampling over your header files.
|
||
You should still maintain the equivalence between the source and this
|
||
file though; every change you make to the .c file should be reflected
|
||
here. */
