More patches from Jeff Law, plus a little cleanup of my own. These changes separate PA-SOM support from PA-ELF support. A sun4-x-hppaosf assembler can now be built. * elf32-hppa.c (elf_hppa_howto_table): Now static. (symext_rootP, symext_lastP, global_value, GOT_value, global_symbol, global_sym_defined, symextn_contents, symextn_contents_real_size, elf_hppa_stub_rootP, elf32_hppa_symextn_map, elf32_hppa_symextn_map_size): Rely on default initialization. (hppa_elf_gen_reloc_type): Macro "UNDEFINED" doesn't need a trailing semicolon. (hppa_look_for_stubs_in_section): Introduce temporaries to make code more readable in 80 columns. * libhppa.h (all functions): Now inline under GNU C. * elf32-hppa.c (AR_WARN): Give argument which caused the invalid argument relocation. (AR_UNIMP): Delete unused macro. (hppa_elf_set_section_contents): Always return a value. (elf32_hppa_backend_table_processing): Likewise.

Add generic PA code which can be shared by both SOM and ELF backends. * Makefile.in: Replace hppa.c with som.c. elf32-hppa.o depends on libhppa.h now. * configure.in (hppa_vec): Needs som.o module instead of hppa.o. * elf32-hppa.c: Include libhppa.h.

Wed Mar 30 16:25:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com) Changes to let BFD return an error indication from get_symtab_upper_bound, bfd_canonicalize_symtab, bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc.

/* About the relocation formatting table...
There are 256 entries in the table, one for each possible
relocation opcode available in SOM. We index the table by
the relocation opcode. The names and operations are those
defined by a.out_800 (4).
Right now this table is only used to count and perform minimal
processing on relocation streams so that they can be internalized
into BFD and symbolically printed by utilities. To make actual use
of them would be much more difficult, BFD's concept of relocations
is far too simple to handle SOM relocations. The basic assumption
that a relocation can be completely processed independent of other
relocations before an object file is written is invalid for SOM.
The SOM relocations are meant to be processed as a stream, they
specify copying of data from the input section to the output section
while possibly modifying the data in some manner. They also can
specify that a variable number of zeros or uninitialized data be
inserted on in the output segment at the current offset. Some
relocations specify that some previous relocation be re-applied at
the current location in the input/output sections. And finally a number
of relocations have effects on other sections (R_ENTRY, R_EXIT,
R_UNWIND_AUX and a variety of others). There isn't even enough room
in the BFD relocation data structure to store enough information to
perform all the relocations.
Each entry in the table has three fields.
The first entry is an index into this "class" of relocations. This
index can then be used as a variable within the relocation itself.
The second field is a format string which actually controls processing
of the relocation. It uses a simple postfix machine to do calculations
based on variables/constants found in the string and the relocation
stream.
The third field specifys whether or not this relocation may use
a constant (V) from the previous R_DATA_OVERRIDE rather than a constant
stored in the instruction.
Variables:
L = input space byte count
D = index into class of relocations
M = output space byte count
N = statement number (unused?)
O = stack operation
R = parameter relocation bits
S = symbol index
T = first 32 bits of stack unwind information
U = second 32 bits of stack unwind information
V = a literal constant (usually used in the next relocation)
P = a previous relocation
Lower case letters (starting with 'b') refer to following
bytes in the relocation stream. 'b' is the next 1 byte,
c is the next 2 bytes, d is the next 3 bytes, etc...
This is the variable part of the relocation entries that
makes our life a living hell.
numerical constants are also used in the format string. Note
the constants are represented in decimal.
'+', "*" and "=" represents the obvious postfix operators.
'<' represents a left shift.
Stack Operations:
Parameter Relocation Bits:
Unwind Entries:
Previous Relocations: The index field represents which in the queue
of 4 previous fixups should be re-applied.
Literal Constants: These are generally used to represent addend
parts of relocations when these constants are not stored in the
fields of the instructions themselves. For example the instruction
addil foo-$global$-0x1234 would use an override for "0x1234" rather
than storing it into the addil itself. */
