uses of SERIAL_READCHAR with readchar, which has better error
checking.
* (e7000_parse_device): Add prototype.
* (readchar): Improve doc. Handle random serial errors.

* (e7000_parse_device): Remove serial_flag arg. It's not
necessary.
* (e7000_open): Split into two pieces. Second part is
e7000_start_remote, and is error protected. Now, when we connect

* (gch): Remove debug output. That's handled by readchar.
* (e7000_read_inferior_memory): Handle errors better.

(INSTALL_XFORM1): Remove.
(install-only): Use $(program_transform_name) directly, rather
than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
(uninstall): Transform name.
* procfs.c: Substantial (but incomplete) changes to support
sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
struct now has substructs like struct flt_ctl instead of
just a fltset_t and has a ctl_fd, status_fd, as_fd, and
map_fd instead of a single fd. Non-sysv4.2mp procfs models
still have the structs and multiple fds, but don't use the
entire struct and the four fds all point to the same thing.
We use PROCFS_USE_READ_WRITE to decide whether to talk to
procfs with reads/writes or use ioctl instead. We use
HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
multiple fds or not. PROC_NAME_FMT is split out into
CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
STATUS_PROC_NAME_FMT.
(procfs_notice_signals): now a necessary wrapper around
(notice_signals): which are the new guts for noticing signals
(open_proc_file): gets a new flag arg used in sysv4.2mp to
determine whether or not to attempt to open the ctl_fd.
(procfs_read_status): new local function, reads procfs status
(procfs_write_pcwstop): new local function, writes a PCWSTOP
(procfs_write_pckill): new local function, writes a PCKILL
(unconditionally_kill_inferior): remove signo since we now
just call procfs_write_pckill().
(procfs_xfer_memory): call lseek with SEEK_SET rather than 0
(proc_iterate_over_mappings): the whole function is ifdefed
on UNIXWARE to keep things readable.
Expanded the syscall_table to include new potential sysv4.2mp
members. Note that all ifdefs of UNIXWARE should be eliminated
if possible or renamed to describe what's being selected for a
bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
IRIX specific code now also checks it's not UNIXWARE.
* config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
* config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
"/debug/%d" as PROC_NAME_FMT used to be
* (hexnumlen): Add prototype. Use max, not min.
* (remote_write_bytes remote_read_bytes): Fix max packet size
calculations to properly account for packet overhead. Also handle
(probably rare) case where remote_register_buf_size isn't set.

* sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
for hosts which default to unsigned chars (such as SGI's).
* (_initialize_sh_tdep): Don't set remote_write_size. It's now
handled automatically in remote.c.
Except for the two m32r modules, this checkin is for
overlay support.
* blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
find_pc_sect_function(), find_pc_sect_partial_function(): new
functions for debugging overlays; pc without section is ambiguous.
* breakpoint.[ch]: add section pointer to breakpoint struct;
add section argument to check_duplicates(); check section as well
as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
breakpoint_thread_match(), bpstat_stop_status()];
add section argument to describe_other_breakpoints();
use INIT_SAL() macro to zero-out new sal structures;
make resolve_sal_pc() fix up the sal's section as well as its pc;
match on section + pc in clear_command() and delete_breakpoint();
account for overlay sections in insert_breakpoints(),
remove_breakpoint() and breakpoint_re_set_one();
all this to support overlays where a PC is not unique.
* exec.c: change xfer_memory() to handle overlay sections.
* findvar.c: change read_var_value() to handle overlay sections.

* m32r-stub.c: mask exit value down to 8 bits; screen out any
memory read/writes in the range 600000 to a00000, and ff680000
to ff800000 (hangs because nothing is mapped there); fix strcpy().
* maint.c: maintenance command "translate-address" supports overlays.
* minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
* objfiles.[ch]: add ovly_mapped field to the obj_section struct;
this constitutes gdb's internal overlay mapping table. Add macro
ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
Add function find_pc_sect_section().
* printcmd.c: modify print_address_symbolic() with overlay smarts;
modify address_info() with overlay smarts; add function sym_info()
to support the INFO SYMBOL command (translate address to symbol(s));
modify disassemble_command() to work on unmapped overlays.
* source.c: use INIT_SAL() to initialize sals.
* symfile.[ch]: change generic_load() to use section's LMA address
instead of VMA address, for overlay sections.
Add numerous functions for finding a PC's section / overlay,
translating between VMA and LMA address ranges, determining if an
overlay section is mapped, etc. Add several user commands for
overlay debugging. Add support for a "generic" form of automatically
reading overlay mapping info from the inferior (based on the default
(simple) overlay manager which Cygnus provides as an example).
* symtab.[ch]: add functions find_pc_sect_symtab(),
find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
for lookup; modify lookup_symbol and decode_line_1() to use them;
modify find_function_start_sal() to account for overlay sections;
add macro INIT_SAL() for initializing struct symtab_and_line.

(struct partial_die_info): Add sibling and has_type fields, remove
unused value field.
(DW_*): Move access macro definitions near the definition of the
attribute structure.
(struct field_info): New structure to pass information about fields
and member functions between die processing routines.
(dwarf2_build_psymtabs_hard): Set cu_header_offset.
(scan_partial_symbols): Do not enter DW_TAG_subprogram dies into
the partial symbol table if the DW_AT_*_pc attributes are missing.
Add file scope base type definitions to the partial symbol table.
Skip over child dies if the die has a sibling attribute.
(add_partial_symbol): Enter global variables with type attributes
and without location descriptors into the partial symbol table.
Store value of DW_TAG_variable dies in the partial symbol table.
Do not enter global variables into the minimal symbol table.

(psymtab_to_symtab_1): Use dwarf2_get_pc_bounds to determine highpc.
(process_die): Move check for DW_AT_low_pc to read_func_scope.
Add a typedef symbol for base type definitions to the symbol table.
Ignore DW_TAG_inlined_subroutine tags for now.
(read_file_scope): Use dwarf2_get_pc_bounds to determine pc bounds.
(read_func_scope, read_lexical_block_scope): Use dwarf2_get_pc_bounds
to determine pc bounds, ignore dies with invalid bounds.
(dwarf2_get_pc_bounds): New routine to extract and validate the
DW_AT_*_pc attributes of a die.
(dwarf2_add_field, dwarf2_attach_fields_to_type, skip_member_fn_name,
dwarf2_add_member_fn, dwarf2_attach_fn_fields_to_type):
New functions to handle fields and member functions.
(read_structure_scope): Rewritten to use them.
(read_array_type): Renamed from dwarf_read_array_type.
Default upper array bound to describe an array with unspecified
length.
Create array types in backwards order, as dwarf2 puts out the array
dimensions from left to right.
(read_subroutine_type): Handle DW_TAG_unspecified_parameters,
DW_AT_artificial and DW_AT_prototyped.
(read_base_type): Make an unsigned type for DW_ATE_boolean.
Pass objfile to dwarf_base_type.

Handle DW_AT_sibling and DW_AT_type.
Follow references when determining DW_AT_name and DW_AT_external
attributes of the die.
Validate DW_AT_*_pc attributes.
(read_full_die): Use read_attribute to read in the attributes.
(read_attribute): New function to read an attribute described
by an abbreviated attribute.
(new_symbol): Relocate symbol value for DW_TAG_label with baseaddr.
Do not set SYMBOL_VALUE_ADDRESS for DW_TAG_subprogram,
SYMBOL_BLOCK_VALUE for the symbol will be set later by finish_block.

descriptor to LOC_UNRESOLVED.
Handle DW_AT_const_value attributes for DW_TAG_variable,
DW_TAG_formal_parameter and DW_TAG_enumerator.
Build a typedef symbol for DW_TAG_base_type.
(dwarf2_const_value): New routine to copy a constant value from an
attribute to a symbol.
(dwarf_base_type): Use passed in objfile, not current_objfile
when calling dwarf2_fundamental_type.
(dump_die): Use DW_* accessor macros to access values of attributes.
(decode_locdesc): Handle DW_OP_plus_uconst.
