* config/tc-hppa.c (fix_new_hppa): If the subtract symbol for
a fixup is $global$ change it to NULL as $global$ is really only
needed long enough to determine the base type of relocation to use.
predefined register table.
(pa_parse_number): Handle %rp in common register shortcut code.
Consistently set return value to -1 for an error. Clean up error
messages and only print them when "print_errors" is true. Handle
empty string case like the HP assembler -- assume a value of
zero.
so GAS can attach unwind descriptor information to a BFD symbol.
* config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
descriptor information to the BFD symbol.
(md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",
they are simply markers. Make R_HPPA_UNWIND_* handling OBJ_ELF
dependent.
(pa_build_unwind_subspace): Whole function is OBJ_ELF dependent.
(pa_entry): Build a R_HPPA_ENTRY relocation when configured for SOM.
(pa_exit): Likewise, but built a R_HPPA_EXIT relocation. Do not
build "end-of-function" symbols for SOM, they are not needed.
(pa_callinfo): Insert framesize into the unwind information as
soon as it's available.
(pa_build_unwind_subspace): Do not insert framesize into the unwind
information here.
field. Define SUBSPACE_DEFINED accessor macro.
(pa_subspace): Allow user to override subspace attributes for
built-in subspaces. Set ssd_defined at the end of fcn -- that
way the attributes can only be changed once. Pass newly allocated
name to is_defined_subspace, not a pointer to the input line.
Fix typo in space/subspace rework.
(is_defined_subspace): Delete unused 2nd arg. All callers changed.
* config/tc-hppa.c (pa_import): If currently in the text segment
and a symbol is imported without type information, set BSF_FUNCTION
for the symbol.
can properly set all the SOM symbol types.
* config/tc-hppa.c (pa_symbol_type): New enum to represent the
symbol types which can be set from an IMPORT/EXPORT statement.
(pa_export_args): Set the pa_symbol_type type based on arguments.
If defined, call obj_set_symbol_type to pass this information on
to the BFD backend.
SOM spaces/subspaces.
* config/tc-hppa.c (USE_ALIASES): New object-format dependent define
to control the use of space/subspace name aliases.
(update_subspace): Accept space chain entry for containing space
as a new parameter. All callers changed.
(pa_get_label): Use current_space rather than pa_segment_to_space.
(pa_define_label): Likewise.
(pa_undefine_label): Likewise.
(md_begin): Change into the (possibly modified) text_section.
(pa_parse_space_stmt): Create a new segment/space if create_flag
is true, and the space name is not one of the two predefined spaces.
(pa_subspace): Use current_space rather than a lookup via
pa_segment_to_space. Reset BFD section flags as required by
the .subspace directive. Likewise for the section alignment.
Pass the current space to update_subspace and create_new_subspace.
(pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
is true. When not using aliases, create a BFD section for each
subspace encountered. When not using aliases replace the default
text, data, and bss segments with new ones.
(create_new_subspace): When not using aliases each subspace has a
section/segment and subsegments are not needed, so set the subsegment
to zero.
obj_set_section_attributes to pass space attributes to the
BFD backend.
(create_new_space): Likewise.
(create_new_subspace): Likewise for subspace attributes using
obj_set_subsection_attributes.
(update_subspace): Likewise for subspace attributes using
obj_set_subsection_attributes.
* config/tc-hppa.c (pa_space): Do not report an error for a .space
directive which does not define a "well-known" space and does
not include a space number as an argument.
* config/tc-hppa.c (pa_def_subspaces): Correct initialization of the
"defined", "loadable", "code_only" and "space_index" fields.
(pa_def_spaces): Correct initialization of the "spnum", "defined",
and "private" fields.
* config/tc-hppa.c (hppa_fix_struct): Delete unnecessary fix_fixP and
fx_next fields.
(hppa_find_hppa_fix): Delete unnecessary function. Fix all
callers to get HPPA fixup information from the tc_fix_data field
in the GAS fixup.
(hppa_fix_root): Delete unnecessary variable.
(fix_new_hppa): Attach HPPA fixup data to the GAS fixup.
* config/tc-hppa.c (pa_set_start_symbol); Delete unwanted
function. Fix all callers.
(subspace_dictionary_chain): Delete unused ssd_start_sym field.
* config/tc-hppa.c (hppa_fix_adjustable): New function to determine
if a particular fixup is adjustable.
* config/tc-hppa.c (log2): Renamed from is_power_of_2. Fix all
callers. Now returns log2 (N) for positive N which are an exact
power of two or -1 for an error.
* config/tc-hppa.c (pa_callinfo): Range check values provided for
ENTRY_GR, ENTRY_FR and ENTRY_SR. Properly adjust vaues before
inserting them into the unwind table.
* config/tc-hppa.c (NEEDS_FIXUP): Delete definition and all references.
(hppa_gen_reloc_type): New object format dependent macro.
(pa_ip): Delete tons of code which was either OBJ_SOM or OBJ_ELF
conditional. The code can (and will) be shared between SOM & ELF
formats in the near future.
(cons_fix_new_hppa, md_apply_fix_1): Likewise.
(pa_build_unwind_subspace, process_exit, pa_exit): Likewise.
(tc_gen_reloc): Use hppa_gen_reloc rather than an object format
specific call.
* config/tc-hppa.c (pa_comm): Set the segment for a common symbol
to bfd_und_section.
* config/tc-hppa.c (pa_big_cons): Delete function and its
declaration. All callers changed to use pa_cons.
From Pete Hoogenboom:
* config/tc-hppa.c (md_atof): Return a NULL on success rather than
an empty string.
* expr.h (expressionS): New field X_unsigned.
* expr.c (operand): Initialize X_unsigned to 1. Set it to 0 for
unary minus case.
(expr) Fix typo resultP to right if missing operand. Set
X_unsigned to 1 when building new expression.
* read.c (potable): Make "octa" and "quad" call cons, not
big_cons.
(cons): Handle bignums. If given an O_constant (small integer) to
fill a big space, turn it into a bignum.
(parse_bitfield_cons): Set X_unsigned field.
(bignum_low, bignum_limit, bignum_high, grow_bignum, big_cons):
Removed.
* read.h (big_cons): Remove prototype.

symbol in expr_section can not be resolved.

symbol we are writing out, give a warning.
* config/tc-h8500.c (parse_reglist): Set X_unsigned.
* config/tc-hppa.c (md_pseudo_table): Change "octa" and "quad" to
call pa_cons, not pa_big_cons.
