* 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.

|
||||
* 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.

aren't using gcc.
