This patch extends the relocation and line number counters for coff-go32 and coff-go32-exe to 32 bits. As I understand it works the same as for PE-COFF: If the number of relocations in an object file exceeds 65534, the NRELOC field is set to 65535 and the actual number of relocations is stored in the VADDR field of the first relocation entry. Executable files have no relocations, and thus the NRELOC field is repurposed to extend NLNNO to 32-bits. bfd * coff-go32.c (COFF_GO32, IMAGE_SCN_LNK_NRELOC_OVFL) (coff_SWAP_scnhdr_in, coff_SWAP_scnhdr_out): Define. (_bfd_go32_swap_scnhdr_in, _bfd_go32_swap_scnhdr_out) (_bfd_go32_mkobject): New functions. * coff-stgo32.c (IMAGE_SCN_LNK_NRELOC_OVFL) (coff_SWAP_scnhdr_in, coff_SWAP_scnhdr_out): Define. (go32exe_mkobject): Call _bfd_go32_mkobject. * coffcode.h (COFF_WITH_EXTENDED_RELOC_COUNTER): Define. (coff_set_alignment_hook): Define function for COFF_GO32_EXE and COFF_GO32. (coff_write_relocs): Enable extended reloc counter code if COFF_WITH_EXTENDED_RELOC_COUNTER is defined. Test for obj_go32. (coff_write_object_contents): Likewise. Pad section headers for COFF_GO32 and COFF_GO32EXE. Use bfd_coff_swap_scnhdr_out instead of coff_swap_scnhdr_out. * cofflink.c (_bfd_coff_final_link): Test also for obj_go32 to enable extended reloc counter. * coffswap.h: (coff_swap_scnhdr_in, coff_swap_scnhdr_out): Declare with ATTRIBUTE_UNUSED. * libcoff-in.h: (struct coff_tdata): New field go32. (obj_go32): Define. * libcoff.h: Regenerate.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
