(enable_break): For SVR4 systems, first try to use the debugger
interfaces in the dynamic linker to track shared library events
as they happen, then fall back to BKPT_AT_SYMBOL code. Convert
BKPT_AT_SYMBOL code to use shared library event breakpoints.
(solib_create_inferior_hook): Simplify BKPT_AT_SYMBOL code,
it no longer needs to restart/wait on the inferior.
* symfile.c (find_lowest_section): No longer static.
* symfile.h (find_lowest_section): Corresponding changes.
Wraps up 7763 work, simplifies BKPT_AT_SYMBOL code somewhat, and allows
debugging of startup code.
to "alpha-*-osf2*" and add comment.
* gdb.base/a1-selftest.exp (test_with_self): Remove "alpha-dec-osf2*"
setup_xfail for "step over execarg initialization" and
"step over corearg initialization".
* gdb.base/callfuncs.exp (do_function_calls): Restore setup_xfail
for "hppa*-*-*", "sparc-*-*", "mips*-*-*", and "alpha-dec-osf2*".
* gdb.base/corefile.exp: Add "alpha-dec-osf2*" setup_xfail when not
gcc compiled for "print coremaker_bss", "print coremaker_ro",
"print func2::coremaker_local", and "backtrace in corefile.exp".
* gdb.base/signals.exp: Build and source signals.ci.

* config/xm-nbsd.h (CC_HAS_LONG_LONG, PRINTF_HAS_LONG_LONG):
#ifdef'd out definitions --- Causes serious gdb failures on
the i386. Need to investigate further before enabling.
* i386b-nat.c (fetch_inferior_registers, store_inferior_registers,
fetch_core_registers): New functions. These functions are defined
if FETCH_INFERIOR_REGISTERS is set. Registers are fetched/stored
with ptrace PT_GETREGS/PT_SETREGS.
Minor build nit.

* breakpoint.c (remove_solib_event_breakpoints): New function.

breakpoints before inserting any new ones. Use a solib event
breakpoint for the breakpoint at "_start".
Remove extraneous "\n" from calls to warning.
Don't leave bogus breakpoints in the breakpoint chain. Simplify
solib_create_inferior_hook and allow for debugging of startup code
(more 7763 related changes).
* breakpoint.c (breakpoint_1): Add missing "sigtramp" to bptypes
name array.
Another minor nit.
alpha coff dynamic symbols for all symbol files. Makes skipping
over the trampoline code work when stepping from a function in a
shared library into a function in a different shared library.

to store actual data. Change types of INT and FLOAT tokens to
typed_val_int and typed_val_float respectively. Create new token
DOUBLE_KEYWORD to specify the string `double'. Make production
for FLOAT use type determined by parse_number. Add production for
"long double" data type.

long double depending upon the type of typed_val_float.dval. Also
allow user to specify `f' or `l' suffix to explicitly specify
float or long double constants. Change typed_val to
typed_val_int.

"double" keyword.

type DOUBLEST. Coerce type of result to long double if either op
was of that type.
* valops.c (value_arg_coerce): If argument type is bigger than
double, coerce to long double.
* (call_function_by_hand): If REG_STRUCT_HAS_ADDR is defined, and
arg type is float and > 8 bytes, then use pointer-to-object
calling conventions.
* valprint.c (print_floating): Arg doub is now type DOUBLEST.
Use appropriate format and precision to print out floating point
values.
* value.h: Fixup prototypes for value_as_double,
value_from_double, and unpack_double to use DOUBLEST.
* values.c (record_latest_value): Remove check for invalid
floats. Allow history to store them so that people may examine
them in hex if they want.
* (value_as_double unpack_double): Change return value to DOUBLEST.
* (value_from_double): Arg `num' is now DOUBLEST.

the executable, not the .o to run the tests from.

(loads into address zero which causes all kinds of problems).
