(parse_comp_unit): Change "version" and addr_size to unsigned ints.
Change "abbrev_offset" to bfd_vma.
(read_indirect_string): Use correct conversion chars in error
message format string, cast bfd_vma's to unsigned long.
(read_abbrevs): Likewise.
(read_attribute_value): Likewise.
(decode_line_info): Likewise.
(scan_unit_for_functions): Likewise.
(parse_comp_unit): Likewise.
* dwarf2.c (struct funcinfo): Move up.
(lookup_address_in_function_table): New argument function_ptr.
Set it.
(lookup_address_in_line_table): New argument function. If function
is non-NULL, use it to handle ``addr'' before the first line note of
the function.
(comp_unit_find_nearest_line): Update and swap calls to
lookup_address_in_function_table and lookup_address_in_line_table.

o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.
(find_rela_addend): New function.
(parse_comp_unit): Call it to find the abbrev offset addend.
(_bfd_dwarf2_find_nearest_line): Initialize and maintain the new
members of dwarf2_debug as debugging information is read.
* dwarf2.c (struct dwarf2_debug): New field dwarf_line_size.
(decode_line_info): Set it. Report error if unit->line_offset is
equal to or larger than it.
as appropriate. Fill in structure initializations. Add variable
initializations. Add casts.
* dwarf1.c (parse_line_table): Change eachLine to unsigned long.
(dwarf1_unit_find_nearest_line): Change i to unsigned long.
* dwarf2.c (struct arange): New type.
(struct comp_unit): Replace LOW and HIGH by member ARANGE.
(arange_add): New function.
(decode_line_info): Keep track of address ranges that a compilation
unit covers.
(comp_unit_contains_address): Return true if address is contained
in _any_ of the address ranges associated with a compilation unit.
(_bfd_dwarf2_find_nearest_line): Call comp_unit_find_nearest_line
on the first comp_unit that contains the address.
* dwarf2.c (struct dwarf2_debug): Add member dwarf_line_buffer.
(decode_line_info): Add variable STASH and initialize it to point
to the per-bfd dwarf2_debug info. Remove static variable
dwarf_line_buffer and use stash->dwarf_line_buffer in its place.
* dwarf2.c (struct line_info): Add member END_SEQUENCE to keep
track of end_sequence markers.
(add_line_info): Add END_SEQUENCE arg.
(decode_line_info): Don't try to infer lo_pc and hi_pc from the
debug-line info---it doesn't work right if a compilation unit
consists of multiple discontiguous code-sequences. It would be
worthwhile to optimize for the common case where a compilation
unit results in a contiguous set of code sequences, but this is
quite tricky to get right for arbitrary DWARF2 files.
(lookup_address_in_line_info_table): Don't use the last line entry
for a compilation unit for anything with an address higher than
this line entry. Also, check for end_sequence markers to
correctly handle discontinuities.
(_bfd_dwarf2_find_nearest_line): When checking previously loaded
compilation units, check all compilation units with each->high==0
just like when reading compilation units.
* dwarf2.c (decode_line_info): Initialize table->files and
table->last_line to NULL to avoid segfaults due to random
values in these members.
(concat_filename): Check for out-of-range file number before
indexing filename table. Segfaults suck.
* dwarf2.c (decode_line_info): Don't truncate address to least
significant 32 bits (breaks 64 bit targets).
(lookup_address_in_function_table): Ditto.
(comp_unit_contains_address): Ditto.
* dwarf2.c (read_abbrevs): Change cast of dwarf_abbrev_buffer
assignment from "unsigned char *" to "char *".
(decode_line_info): Likewise for dwarf_line_buffer assignment.
