11b5fe1b1d * (amiga_write_object_contents): Fix HUNK_DEBUG size calculation for 64bit hosts. 
The broken code used the wrong structure for the size calculation. This bug was
  hidden on 32bit hosts since both structures have the same size on such hosts.
  The AmigaOS program loader refuses to load programs with a defective structure.
 2014-11-27 21:01:50 +00:00
Gunther Nikl

an .o or .obj extension.

e431b46fb2 (amiga_write_section_contents): Use datatype of "reloc_counts" also for 
"reloc_count". Better error message for a relocation against an omitted
section. Replace BFD_FAIL with "bfd_set_error/return FALSE" since linking
cannot succeed. Prevent a possible endless loop when writing relocations.
Fail link operation if not all relocations could be written.

* amigaos.c (amiga_add_reloc): Do not cache target_hunk.
(amiga_get_reloc_upper_bound): Remove format check since this is already

 2008-12-07 18:54:51 +00:00
Gunther Nikl
1a66b4b1bf * libamiga.h (amiga_reloc_type): Switch from amiga_symbol to generic asymbol.

96fb56c052 (amiga_ardata_type): Add new member. 
(amiga_read_ar_hdr): Strip path part from read hunk name. If object file does
not have a valid hunk name, fake an unique object name to match expectations
of eg. the GCC build machinery about extracted object names from a link lib.

Gunther Nikl
acade3748e (MAX_NAME_SIZE): Change its value to zero which enables unlimited length of 
symbol names in write_name.
(write_name): Fix 64bit bug. The old code used a structure with an embedded
long and assumed its size as 4 bytes. The new code writes all data with
single writes. Now the AmigaOS backend should really be 64bit clean.
The length of a symbol name is no longer restricted to MAX_NAME_SIZE
characters. The old behaviour can be re-enabled by setting it to a non-zero
value which will then be used as length limit.
