gdb/doc/ChangeLog:
2003-04-09 Jim Blandy <jimb@redhat.com>
* gdb.texinfo (Symbols): Document 'maint list symtabs' and 'maint
list psymtabs'.
* frame.h: Mention what replaced what in "struct frame_info".
* hppa-hpux-tdep.c: Use get_frame_base, get_frame_pc and
deprecated_update_frame_base_hack and
deprecated_update_frame_pc_hack.
* hppa-tdep.c: Ditto.
to read_reg and update its comment. Remove regnum member.
* dwarf2expr.c (execute_stack_op): Remove memaddr and expr_lval.
Don't call read_reg when setting in_reg. Call read_reg to get
the frame base if it's in a register. Return the register number
on the stack instead of in the context. Remove extra arguments
to read_reg.
* dwarf2loc.c (dwarf_expr_read_reg): Remove extra arguments.
(dwarf2_evaluate_loc_desc): Call value_from_register. Expect
the register number on the expression stack.
(needs_frame_read_reg): Remove extra arguments.
* dwarf2expr.c (dwarf2_read_address): Renamed from read_address;
made non-static.
(execute_stack_op): All callers updated.
* dwarf2expr.h: Add prototype for dwarf2_read_address.
* dwarf2loc.c (find_location_expression): New function.
(dwarf_expr_frame_base): Call it.
(dwarf2_evaluate_loc_desc): Handle 0-length location expressions.
(dwarf2_tracepoint_var_ref): New function, broken out from
locexpr_tracepoint_var_ref.
(locexpr_tracepoint_var_ref): Call dwarf2_tracepoint_var_ref.
Make static.
(loclist_read_variable, loclist_read_needs_frame): New functions.
(loclist_describe_location, loclist_tracepoint_var_ref): New
functions.
(dwarf2_loclist_funcs): New struct location_funcs.
* dwarf2loc.h (struct dwarf2_loclist_baton): New type.
(struct dwarf2_locexpr_baton): Add comments.
(dwarf2_loclist_funcs): New extern.
* dwarf2read.c (struct comp_unit_head): Remove DIE member, add
base_address and base_known.
(dwarf_loc_buffer): New variable.
(struct dwarf2_pinfo): Add dwarf_loc_buffer and dwarf_loc_size.
(DWARF_LOC_BUFFER, DWARF_LOC_SIZE): New macros.
(dwarf2_has_info): Initialize dwarf_loc_offset.
(dwarf2_build_psymtabs): Read in .debug_loc.
(dwarf2_build_psymtabs_hard): Use DWARF_LOC_BUFFER and
DWARF_LOC_SIZE.
(psymtab_to_symtab_1): Likewise. Move base address calculation
here, from...
(dwarf2_get_pc_bounds): ... here. Use the base address from
cu_header.
(dwarf2_symbol_mark_computed): Handle location lists.
* frame.c (get_frame_id): Return this frame's "id".
(legacy_get_prev_frame): Set prev's frame ID code_addr to the
function start.
(legacy_saved_regs_this_id): Replace function body with
internal-error.
(deprecated_frame_xmalloc): Mark the frame ID as valid, use
FRAME_OBSTACK_ZALLOC.
(create_new_frame): Mark the frame ID as valid.
gdb.c++/userdef.cc: Place comments on the lines to which the
marker function might return.
* gdb.c++/derivation.exp, gdb.c++/overload.exp,
gdb.c++/userdef.exp: Look for those comments to check that we've
returned to the right place, instead of checking line numbers.
* d10v-tdep.c (d10v_frame_this_id): Set the code addr to the
frame's function's address. Simplify.
(d10v_frame_unwind_cache): Check that the frame's function is
non-zero.
ld-mips-elf/elf-rel-got-n64.d, ld-mips-elf/elf-rel-xgot-n32.d,
ld-mips-elf/elf-rel-xgot-n64.d: New.
* ld-mips-elf/mips-elf.exp (hasn32): Define as condition for
new tests to run.
* config/tc-mips.c: Use signed add for n32 address arithmetic.
(append_insn): When filling delay slots with instructions
that have fixups that tc_gen_reloc might consider modifyable
in variant frags, start a new frag.
(load_address): Generate GOT_DISP with of without offset
depending on whether symbol is local. For -xgot, use
GOT_PAGE/GOT_OFST or GOT_HI16/GOT_LO16.
(macro) <M_DLA_AB, M_LA_AB>: Likewise.
<M_JAL_A>: In NewABI, use CALL16 or GOT_DISP for small got,
CALL_HI16/CALL_LO16 or GOT_PAGE/GOT_OFST for big got.
<ld_st>: In NewABI with small got, always use
GOT_PAGE/GOT_OFST, with the latter in the load/store
instruction. With big got, use GOT_HI16/GOT_LO16 or
GOT_PAGE/GOT_OFST.
(tc_gen_reloc): Adjust variant frags with GOT_DISP in NewABI.
Add tc_frag_data.tc_fr_offset to addends. Decay CALL16,
GOT_OFST and GOT_DISP to GOT_DISP in NewABI.
(md_convert_frag): Use memmove for safe copying of overlapping
regions.
GOT_PAGE/GOT_OFST referencing overridable symbol to
GOT_DISP/addend.
(_bfd_mips_elf_check_relocs): Handle GOT_PAGE referencing
global symbol as GOT_DISP.
