* seclet.c (rel): don't load sections without the SEC_LOAD bit.
Thu Oct 15 10:16:35 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* coff-m68k.c (m68k_howto2type, SELECT_RELOC): new function to
work out a coff relocation type from a howto's attributes rather
than using the input r_type field. This fixes PR1677 and allows
conversion of a.out relocs to coff relocs.
* coffcode.h (coff_write_relocs): if supplied a relocation
relative to an absolute symbol, use the right symbol index.
* reloc.c (bfd_perform_relocation): do a partial link for coff
relocs right.
* changes to support i386-sysv with shared libraries:
* coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined,
check for .data2; if _LIB is defined, check for it; map
SEC_NEVER_LOAD to STYP_NOLOAD.
(styp_to_sec_flags): map STYP_NOLOAD to SEC_NEVER_LOAD.
(make_a_section_from_file): if TWO_DATA_SECS, accept .data2.
(coff_write_object_contents): force vaddr of .lib to 0; set scnptr
if section has contents, not just if it is loadable; if
TWO_DATA_SECS, check for .data2
(coff_set_section_contents): set vma of .lib section to number of
.lib sections.
* coff-i386.c: define TWO_DATA_SECS; use a special CALC_ADDEND;
don't define coff_write_armap to bsd_write_armap.
* hosts/i386v.h: don't include <utime.h>, since it is not provided
by SVR3.2.
Wind River stole them from the Sun Unix distributions.
We can't distribute them in an FSF GDB release.
We should even rewrite them for our own releases, though that is not
as urgent.
Until these two files are rewritten, VxWorks support in GDB will not compile.
The i960 support can be gained by just rewriting the ptrace.h file.
Only small amounts of the reg.h file need to be rebuilt -- compile
remote-vx.c to see what is needed.

is null.
* tm-sun4sol2.h (PROLOGUE_FIRSTLINE_OVERLAP): Remove -- it
causes problems in setting breakpoint in the right place in
functions with `float' args which are passed as doubles.
* xm-vaxbsd.h (MEM_FNS_DECLARED): Avoid erroneous redecl's.
* config/rs6000.mh (NATDEPFILES): Add corelow.o.
* dwarfread.c: include <sys/types.h> for SCO.
* infptrace.c: Don't include ptrace.h under SCO.
* config/i386sco.mh: Use -D_POSIX_SOURCE instead of -posix for
gcc.
* config/i386v.mt: Add exec.o to TDEPFILES.
* irix4-nat.c: Remove externs of registers[], include inferior.h
instead.
* mips-nat.c: Explicitly initialize zerobuf to 0!
* mips-tdep.c (init_extra_frame_info): Undo John's last change.
Always setup fci->frame, even if it's non-zero. Too many places
depend upon this behavior (and I have to get a release out the
door)!
* mipsread.c (parse_partial_symbols, psymtab_to_symtab_1): Set
processing_gcc_compilation if we find the embedded stabs marker.
This fixes several bugs with finding the location of short or char
function parameters passed on the stack.
* Support for i386-sysv.
obj-coffbfd.c (do_relocs_for, write_object_file): set segment
addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
be used to set them all to zero as was done before.
(fill_section): segment addresses now set in write_object_file.
(fill_section): Don't set STYP_NOLOAD for .bss section.
(fixup_segment): 386 uses strange common symbol format.
tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
compatibility with SVR3.2 linker.
coredep.c, but zero out FP_REGNUM & ZERO_REGNUM so that stack
backtraces from core files work.
* config/decstation.mh, config/irix3.mh: Remove coredep.o.
Functions are now defined in mips-nat.c.
* Support for i386-sysv.
configure.in: check for i386-*-sysv* and i386-*-sco*.
i386coff.sc-sh: rewrote to support SVR3 by default.
ldctor.c (find_constructors): preserve stat_ptr.
ldlang.c (wild_doit): initialize vma and size of new output
section to corresponding input section. This is required for
shared library support.
(lang_size_sections): don't modify vma and size of sections which
are never loaded (for shared libraries).
ldwrite.c (copy_and_relocate): copy the contents of any section
which has contents, not just sections which are loaded (for shared
libraries).
