(single_step, sparc_init_extra_frame_info, examine_prologue):
Use fetch_instruction instead of read_memory_integer
to ensure that instructions are always read as big-endian.
* gdbtk.c: Fixed a goof in the definition of the gdb_get_args &
gdb_get_locals Tcl commands. Moved the previous ChangeLog entry
from ChangeLog to ChangeLog-gdbtk...
* gdbtk.c: Add an object call wrapper for the new Tcl_Obj based
commands. This way the obj commands will also go through
catch_errors. This is just a bandaid while I rewrite the
string-based commands to use the object format.
%o0-%o5 as 64-bit values; compensate for stack bias.
(USE_STRUCT_CONVENTION): We only pass pointers to structs
if they're larger than 32 bytes.
(REG_STRUCT_HAS_ADDR): Ditto.
* sparc-tdep.c (sparc_init_extra_frame_info): Use read_sp()
instead of read_register. If the target is a sparc64 and the frame
pointer is odd, compensate for the stack bias.
(get_saved_register): Use read_sp().
(DUMMY_STACK_REG_BUF_SIZE): Use FP_REGISTER_BYTES.
(sparc_push_dummy_frame): Use read_sp()/write_sp(). On sparc64,
save the PC, NPC, CCR, FSR, FPRS, Y and ASI registers.
(sparc_frame_find_saved_regs): Use read_sp(). Read the PC, NPC,
CCR, FSR, FPRS, Y and ASI registers from the frame, if it's a
dummy frame.
(sparc_pop_frame): Use write_sp(). If the target is a sparc64 and
the FP is odd, compensate for stack bias.
(sparc_store_return_value): Right-justify the return value before
writing it to %o0.
(sparc_fix_call_dummy): Don't NOP out part of the call dummy on
sparc64.
(sparc64_read_sp, sparc64_read_fp, sparc64_write_sp,
sparc64_write_fp, sp64_push_arguments,
sparc64_extract_return_value): New functions to support the
sparc64 ABI.
* dwarfread.c (handle_producer): Set processing_gcc_compilation to
the right version number.
* dwarf2read.c (read_file_scope): Assume we're processing
GCC2 output.
Fri May 1 19:51:32 1998 Frank Ch. Eigler <fche@cygnus.com>
* stabsread.c (read_one_struct_field): Do not override supplied
bitfield size for a range type value.
* gdbtypes.c (create_range_type): For a range with positive
lower limit, declare range type as unsigned.
all breakpoints are requested.
* stabsread.c (define_symbol): Record parameter types from Sunpro
function stabs in the TYPE_FIELDS of the function type.
* Makefile.in (config-check-targets, config-check-hosts): Removed.
1998-04-30 Paul Eggert <eggert@twinsun.com>
* Makefile.in (maintainer-clean):
Don't get ahead of yourself and delete Makefile
before running `make'.
(local-maintainer-clean, do-maintainer-clean): New rules.
* nec4102rom.c : New file implements rom monitor adapter for
nec-vr4102 board. This board hosts the vr4111 chip. This file
required extenstions to the monitor_ops structure, hooks for wiat
filter, new flags. This version does not support more than one
breakpoint and resuming after a breakpoint in 16 bit mode is
completely disfunctional. * monitor.h : Defined additional hooks
for dmpregs, confinuer_hooks and wait_filter. These additions
require that all rom monitor interfaces be recoded to to
initializa monitor ops using assignments rather than static
structure initialization. Added new bits to flags
MO_EXACT_DUMPADDR, MO_HAS_BLOCKWRITES
* monitor.c (RDEBUG): Conditional tracing throughout the file.
(fromhex): Now recognized upper cse hex digits
(monitor_printf_noecho):
(monitor_readchar): Tracing interferes with input timing.
(monitor_open): Register different memory write functions with
dcache_init if MO_HAS_BLOCKWRITES.
(flush_monior_dcache): Added as an additional utilty.
(monitor-resume): Call continue hook if one has been supplied.
(monitor_wait_filter): New function Factored out of monitor wait
and used if alternate wait-filter has not been provided.
(monitor_wait): call alternate wait filter if provided. Call
monitor_dump_regs, a new function factored out from inline code.
(monitor_dump_block): A new function used as a utility when
monitors must dump several blocks of registers using different
commands.
(monitor_dump_regs): Call alternate function if provided. Uses new
hook in monitor.h.
(monitor_write_memory): Engage previouly added hook
MO_FILL_USES_ADDR.
(monitor_write_even_block): new function supports writing long
blocks of 4byte words.
(longlongendswap): new internal function
(monitor_write_memory_longlongs): new function writes large blocks
using command to enter a long long.
(monitor_write-memory_block): new Function figures out which block
mod to use.
(monitor_read_memory): Can now handle dump formats in which the bytes
preceeding the requested data is not printed.
* monitor.h: Added new fields to the structure
(INSTALLED_LIBS): Include GDBTKLIBS.
(CLIBS): Likewise.
* configure: Rebuilt.
* configure.in: Put Tcl/Tk libs into GDBTKLIBS, not LIBS.
(GDBTKLIBS): AC_SUBST.
make it work on the simulator.
(FIX_CALL_DUMMY): Convert to function call instead of inline code.
(sparc_fix_call_dummy): Declare.
* sparc-tdep.c (sparc_fix_call_dummy): New function, taken from
old FIX_CALL_DUMMY macro, with additional fixes for simulator.
(sparc_push_dummy_frame): Set registers differently on simulator
to prevent corrupted register window save areas.
fstat on ldinfo_fd fails. Use objfile->obfd instead of vp->bfd
to check for reference to the same file.
* target.c (target_read_string): Handle string transfers at the
end of a memory section gracefully.
* gdb.c++/virtfunc.cc: Declare extern "C" printf to return int,
not void.
fche says he vaguely remembers a problem with returning int instead of
void, but ISO C sez printf returns int, so let's see what happens.
* configure.in (strerror): Check if function must be declared.
* acconfig.h (NEED_DECLARATION_STRERROR): New define slot.
* gdb_string.h (strerror): Function declaration issued if
NEED_DECLARATION_STRERROR.
* configure, config.in : Files regenerated.
* gdbtk.c (_initialize_gdbtk): add cygwin32 specific code to
allow `gdb -nw' to work when specified specified from a windows
console-mode command line.
dump gracefully.
* solib.c (find_solib): Use catch_errors around call to
solib_map_sections. Use warning instead of error if reading of
the shared library name fails.
(solib_map_sections): Change return and argument types to make
it callable from catch_errors.
(symbol_add_stub): Avoid GDB core dump if solib->abfd is NULL.
* irix5-nat.c, osfsolib.c (xfer_link_map_member, solib_map_sections,
symbol_add_stub): Ditto.
* coffread.c (decode_base_type): Treat a long field with size greater
than TARGET_LONG_BIT as long long.
* values.c (value_from_longest): Print code value in error message.
* gdb/gdb_string.h (strdup): Declare only if not defined as a
macro.
Mark glibc development versions are defining strdup as a macro and the
prototype hosees it. Either way, this patch shouldn't cause problems.
* procfs.c: Added replacement macros for LWP stuff. Fixed support
for UnixWare / SVR4.2MP targets and any targets which use
multi-file /proc entries. Fixed support for hardware watchpoints.
* solib.c: SCO needs some of the same code as SunOS. Change
preprocessor conditionals.
* config/i386/i386sco5.mt: New file.
* config/i386/tm-i386sco5.h: New file.
* config/i386/i386sco5.mh (NATDEPFILES): add i386v-nat.o.
* config/i386/nm-i386v42mp.h
(TARGET_HAS_HARDWARE_WATCHPOINTS): define.
Add other macros for hardware assisted watchpoints.

(TARGET_HAS_HARDWARE_WATCHPOINTS): define.
* config/i386/nm-linux.h (target_remote_watchpoint): Pass
'type' through to i386_insert_watchpoint.
Mon Apr 20 14:12:30 1998 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (wait_for_inferior): Don't add signalled processes
as new threads.
* procfs.c (wait_fd): Note if LWP has exited.
(procfs_wait): use GETPID to get process ID.
NOTE: I didn't commit Kean's changes to configure.host/configure.tgt
yet because they are kind of bogus and I'm punting back to him to let
him figure out what he's trying to do. So configuring for UnixWare
may not work just yet.
* gdb.base/branches.c: Code with lots of loops and
subroutines. Used to test gdbs ability to single step through PC
changes, especially to test mips-tdep.c:mips_next_pc
(sparc_extract_return_value): New function, required to handle
machines without floating point.
(sparc_store_return_value): Ditto.
* config/sparc/tm-sparc.h (EXTRACT_RETURN_VALUE): Call
sparc_extract_return_value instead of using inline code.
(sparc_extract_return_value): Declare.
(STORE_RETURN_VALUE): Call sparc_store_return_value instead
of using inline code.
(sparc_store_return_value): Declare.
work correctly on little-endian hosts.
(sparc_push_arguments): New function.
(gdb_print_insn_sparc): New function.
(_initialize_sparc_tdep): Make gdb_print_insn_sparc the default
disassembler, so that SPARClite-specific instructions will
be recognized.
* sparcl-tdep.c (readchar): Print debugging information.
(debug_serial_write): New function, a replacement for SERIAL_WRITE
that prints debugging information.
* config/sparc/tm-sparc.h (PUSH_ARGUMENTS): Define.
(sparc_push_arguments): Declare.
* configure.tgt: Switch over to use tm-4320.h. Since I switched to
MIPS EABI the fixes are no longer backward compatible with 4300.
* tm-vr4320.h: Added
* vr4320.mt: Added
zap one group of persistent gdb testomat failures.
Mon Apr 13 22:32:51 1998 Frank Ch. Eigler <fche@cygnus.com>
* gdb.c++/virtfunc.cc: Make extern "C" printf declaration pass
more rigorous EGCS C++ error checking.
* utils.c: (warning) added call to warning_hook
* source.c: (find_source_lines) modified to call warning in case
of source vs. executable time stamp mismatch. Simplified object
file check. Initialized mtime to 0.

* gdbtk.c: (perror_with_name_wrapper) new function to call
perror_with_name safely.
(gdb_loadfile) added source vs. executable time stamp check.
(gdbtk_warning) new function to pass a warning message to the gui.
(gdbtk_ignorable_warning) new function to pass a warning
to the gui. Used only for the src. vs. exec check.
(gdbtk_init) added warning_hook
added include <sys/stat.h>
timer interval a little.
(gdbtk_stop_timer): Include on all platforms.
(gdbtk_wait): No more signals! Use a timer on all platforms to keep the
GUI alive.
(gdbtk_init): Remove FIOASYNC and all x_fd references. Now using timers
on all platforms.
Update support for x86 Solaris 2.
* config/i386/tm-i386sol2.h, nm-i386sol2.h: New configuration
files for x86 Solaris 2.
* config/i386/i386sol2.mt, i386sol2.mh: Use them.
* config/sparc/tm-sun4sol2.h (PROCFS_GET_CARRY): New macro, extract
carry flag from a given regset.
(IS_STATIC_TRANSFORM_NAME): New macro, check if a symbol name
is a SunPro transformed name.
* i386-tdep.c (sunpro_static_transform_name): New function to
extract the source name from a SunPro transformed name.
* inferior.h (procfs_first_available, procfs_get_pid_fd):
Add prototypes.
* infrun.c (wait_for_inferior): Handle breakpoint hit in
signal handler without intervening stop in sigtramp.
* procfs.c (procfs_lwp_creation_handler): Use PROCFS_GET_CARRY
instead of direct access to the status register.
(procfs_get_pid_fd): New function, returns procfs fd for a given pid.
* sol-thread.c (ps_lgetLDT): New function, returns LDT for a given
lwpid.

to check for a SunPro transformed symbol name.
* gdb.base/help.exp: Clean up `help set args' and `help show args'
tests.
* gdb.base/interrupt.exp: Add "i*86-*-solaris2*" xfail for calling
function when asleep.
* gdb.base/signals.exp: Add "i*86-*-solaris2*" xfails. Add comment
for i*86 Linux and SVR4 signal handling problems.
Remove linux xfail for `next to handler in signals_tests_1', fixed
by recent infrun.c change.
Limit backtrace to 10 frames to avoid timeout problems with infinite
stack backtraces.
Adjust expect pattern in `handle all print' test to match Apr 28 1997
target.[ch] change.
* mips-tdep.c (unpack_mips16): Fixed instruction decoding, lots of
bit pattern interpretations. mips_fetch_instruction does not work
for 16 bit instructions. Some confusion remains about sign
extension in backward branches.
(mips32_relative_offset): Sign extension
(mips32_next_pc): Major debugging, bit pattern interpretation
(print_unpack): debugging printf
(fetch_mips_16): new funtion, key on PC low bit, not symbol table
(mips16_next_16): Initial major debugging of this function. Lots
of bit pattern mistakes.
(mips_next_pc): key on low bit of PC, not symbol table.
* symfile.c(generic_load) : Added a download verification which
reads back the loade code. Download chunk size is now a defined
macro. Fixed a bug in which downloading slips into loading one
byte at a time. Lower level functions in monitor.c can load long
sequences of bytes and make use of these fixups. Referencing
bfd-start_address directly was incorrectly getting zero for start.
section in an ELF file, override a symbol's ECOFF section with its
ELF section. Also, fix stabs continuation where a stabs string
continues for more than one continuation.
Thu Apr 2 12:47:41 1998 Frank Ch. Eigler <fche@cygnus.com>
* sol-thread.c (sol_thread_store_registers): Save & restore new
value of single updated register to prevent accidental clobbering.
