below the code to sort out additions and removals. That way, we
always catch all loaded shared libraries whose symbols we haven't
grabbed yet.
* solib.c (solib_add): Don't try to free a shared object's objfile
if it doesn't have one. Duh.
* solib.c (solib_add): If a pattern was given, but it doesn't
match any currently loaded shared libraries, print a message;
don't just be silent.

(REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Likewise.
(I386_DJGPP_TARGET): Don't define, it's no longer required.
(LOW_RETURN_REGNUM, HIGH_RETURN_REGNUM): Remove definition,
i386-tdep.c defines it for all x86 targets.
(LD_I387, HEX_LONG_DOUBLE_INPUT): Remove.
* config/djgpp/fnchange.lst: Add i386-linux-tdep.c.

* wrapper.[ch] (struct gdb_wrapper_arguments): Change fields into
unions, since they are all used to hold both pointers and ints
at various times. Casting pointer to int and vice versa gives
warnings (and is not safe) if they are not the same size.

casting problems when int and pointer are not the same size.
* event-top.c (command_handler): use data as a union.

paddr_t to psaddr_t. This mistake appears to date from an
erroneous man page in Solaris 2.5 -- the correct type from the
system headers has always been psaddr_t.
(ps_pdread, ps_pdwrite, ps_ptread, ps_ptwrite): ditto.
(rw_common): ditto.
From Philippe De Muyter <phdm@macqel.be>
* event-loop.c (sys/types.h): File now included unconditionally.

Linux-specific signal trampoline detection, and should be moved to...
* i386-linux-nat.c: ... here.
* config/i386/tm-linux.h (I386_LINUX_SIGTRAMP): No need to define
this any more, since we're not enabling OS-specific code in a
OS-independent file.
(File Options): Add @cindex entries for each command-line option.
Document --epoch, --annotate, --async, --interpreter, --write,
--statistics, and --version.

shared objects with GDB's list, and do the required loads and
unloads.
(info_sharedlibrary_command, solib_address): Don't use find_solib
to walk the list of shared libraries: call solib_add, and then
walk the list at so_list_head normally.
* objfiles.c (free_objfile): Don't call CLEAR_SOLIB, and don't
detach the core target. These tasks are taken care of elsewhere.
* target.c (remove_target_sections): New function.
* target.h (remove_target_sections): New declaration.
* solib.c (symbol_add_stub): Check whether we've already created
an objfile for this shared object first, before doing all that
work to compute section addresses, etc.

update callers.
(solib_add_common_symbols): Change parameter type to CORE_ADDR,
update callers.
(open_symbol_file_object, find_solib): Change type of lm variable
to CORE_ADDR.

been installed yet.
(new_root_variable): Initialize use_selected_frame variable.
(value_of_root): This is where most of the work to handle "current
frame" variables was added. Most of the complexity involves
handling the case where the type of the variable has changed.
(varobj_create): Add a "type" argument, to tell if the
variable is one of these "current frame" variables. Also protect
call to parse_exp_1 from long jumping.
* mi-var-block.exp: The error report from varobj_create changed
since I am now trapping parse_exp_1 errors. Change the tests to
match the new error message.

argument to be identical to the corresponding message in
`inftarg.c'. This makes the testsuite happy.
* i386gnu-nat.c (gnu_store_registers): Make sure the T bit in the
%eflags isn't modified. This fixes a bug where every call to a
function in the program beyond the first call would fail.
* gdb.base/long_long.exp: Correct test suite failure when printing
a long long value as a double on ARM platforms.
ARM doubles use a hybrid endian format. It is not strictly little or big
endian. It is little endian with the words swapped.

mi_cmd_data_write_register_values.
* mi-main.c (mi_cmd_data_write_register_values): New
function. Write a value into a register.
* mi-disassemble.exp: Don't assume numbers for the offset
values. They can be different depending on the architecture.
* mi-watch.exp (test_watchpoint_triggering): In same cases the
type can be 'hw wathcpoint' not just 'watchpoint'. Adjust for that.

HAVE_PTRACE_GETREGS isn't defined.
(fetch_regs): Reset `have_ptrace_getregs' if ptrace call fails
with EIO.
(fetch_inferior_registers, store_inferior_registers): Fall back on
the method use in `infptrace.c' (by calling
old_fetch_inferior_registers and old_store_inferior_registers) if
`have_ptrace_getregs' isn't set.
* i386-linux-nat.c: Use elf_gregset_t and elf_fpregset_t instead
of gregset_t and fpregset_t. Those are the only names that are
guaranteed to specify the right types for all supported Linux
systems out there.
Various doc fixes and gratitious local variable renames, all in an
attempt to stress similarities between the code and unify the
terminology used. Use ISO-C all over.
(regmap): Remove trailing comma.
(FPREG_ADDR): Renamed from FPREGSET_T_FPREG_ADDR.
(convert_to_gregset): Make static. Remove GDB_REGS argument. It
is unnecessary and wasn't used anyway. All callers changed.
(convert_to_fpregset, convert_to_xfpregset): Likewise.
(fetch_regs, store_regs): Remove unused variable `regno'.
(fill_fpregs): If REGNO is not -1, only update the specified
register.
(fetch_core_registers): Renamed from
i386_linux_fetch_core_registers. There is no need for a unique
name since the function is static anyway.
(linux_elf_core_fns): Renamed from i386_linux_nat_core_functions
since it is more descriptive.
Fix support for Linux/i386 signal trampolines. The old approach
didn't work for Linux 2.2 and beyond, and didn't work with recent
versions of the GNU C library.

(i386_linux_in_sigtramp): New function.
(i386_linux_sigcontext_addr): New function. Recognize the names
of the signal tranmpolines used by recent versions of the GNU C
library, and add support for RT signals.
