* elf.c, elfcode.h, libelf.h: Serious reorganization.
Deleted `thunk' structure, merged into tdata, duplicate data eliminated. Rearranged functions, grouping by function. Broke up many functions in elfcode.h, re-ordered many parts of file writing to handle unpredictable state of section relocation table as provided by various applications. Still needs cleanup: Merge functions back together, split out data structure with only data that is used only when writing out object file. * elf.c (bfd_elf_generic_reloc): New function, taken from coff-mips.c. * elf32-sparc.c (elf_sparc_howto_table): Use it, to work around bfd_perform_relocation lossage.

* elf.c, elfcode.h, libelf.h: Serious reorganization.
|
||||
Deleted `thunk' structure, merged into tdata, duplicate data
|
||||
eliminated.
|
||||
Rearranged functions, grouping by function.
|
||||
Broke up many functions in elfcode.h, re-ordered many parts of
|
||||
file writing to handle unpredictable state of section relocation
|
||||
table as provided by various applications.
|
||||
Still needs cleanup: Merge functions back together, split out
|
||||
data structure with only data that is used only when writing out
|
||||
object file.
|
||||
|
||||
* elf.c (bfd_elf_generic_reloc): New function, taken from
|
||||
coff-mips.c.
|
||||
* elf32-sparc.c (elf_sparc_howto_table): Use it, to work around
|
||||
bfd_perform_relocation lossage.
|
||||
|
||||
* Makefile.in (BFD_LIBS): Include coff-mips.o and coff-msym.o, so
|
||||
that gdb will link.
|
||||
(ofiles): Don't use sort or uniq; do it with sh constructs.

DESCRIPTION
|

Helper functions for GDB to locate the string tables.
|

Since BFD hides string tables from callers, GDB needs to use an
|
||||
internal hook to find them. Sun's .stabstr, in particular,
|
||||
isn't even pointed to by the .stab section, so ordinary
|
||||
mechanisms wouldn't work to find it, even if we had some.
