Fix some infrastructure to be able to cope with host and target
machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)
* value.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
the correct pointer type to value_from_long{est}.
* remote-vx.c: Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).
* valops.c (value_string): Find malloc with lookup_misc_func, not
raw search.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.

bound.
|
|
|
|
|
|
|
|
|
|
FIXME: A previous comment here indicated that this routine should be
|
|
|
|
|
substracting the array's lower bound. It's not clear to me that this
|
|
|
|
|
is correct. Given an array subscripting operation, it would certainly
|
|
|
|
|
work to do the adjustment here, essentially computing:
|
|
|
|
|
|
|
|
|
|
(&array[0] - (lowerbound * sizeof array[0])) + (index * sizeof array[0])
|
|
|
|
|
|
|
|
|
|
However I believe a more appropriate and logical place to account for
|
|
|
|
|
the lower bound is to do so in value_subscript, essentially computing:
|
|
|
|
|
|
|
|
|
|
(&array[0] + ((index - lowerbound) * sizeof array[0]))
|
|
|
|
|
|
|
|
|
|
As further evidence consider what would happen with operations other
|
|
|
|
|
than array subscripting, where the caller would get back a value that
|
|
|
|
|
had an address somewhere before the actual first element of the array,
|
|
|
|
|
and the information about the lower bound would be lost because of
|
|
|
|
|
the coercion to pointer type.

(Idea from pierre@la.tce.com (Pierre Willard).)
* value.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
the correct pointer type to value_from_long{est}.
* remote-vx.c: Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).
* valops.c (value_string): Find malloc with lookup_misc_func, not
raw search.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.

Fix some infrastructure to be able to cope with host and target
machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)
* value.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
the correct pointer type to value_from_long{est}.
* remote-vx.c: Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).
* valops.c (value_string): Find malloc with lookup_misc_func, not
raw search.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.

Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
New files.
* Makefile.in: Add new files and dependencies.
* configure.in: Add alpha target.
* config/alpha/alpha-osf1.mh (NATDEPFILES): Add osfsolib.o
* config/alpha/alpha-osf1.mh (MH_CFLAGS): Remove, we can handle
shared libraries now.
* config/alpha/xm-alpha.h: Cleanup, get MAKEVA_* defines right.
* defs.h (CORE_ADDR): Make its type overridable via CORE_ADDR_TYPE,
provide `unsigned int' default.
* breakpoint.c (breakpoint_auto_delete): Delete only if we really
stopped for the breakpoint.
* stabsread.c, stabsread.h (define_symbol): Change valu parameter
to a CORE_ADDR.
* stabsread.c (read_range_type): Handle the case where the lower
bound overflows and the upper doesn't and the range is legal.
* infrun.c (resume): Do not step a breakpoint instruction if
CANNOT_STEP_BREAKPOINT is defined.
* inferior.h (CALL_DUMMY_LOCATION): New variant AT_ENTRY_POINT.
Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
FIX_CALL_DUMMY can be used to set up everything for the dummy.
The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
* infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case. Use
the expected breakpoint pc when setting up the frame for
set_momentary_breakpoint.
* symfile.c (entry_point_address): New function for AT_ENTRY_POINT
support.
* valops.c (call_function_by_hand): Handle AT_ENTRY_POINT case.

Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
New files.
* Makefile.in: Add new files and dependencies.
* configure.in: Add alpha target.
* config/alpha/alpha-osf1.mh (NATDEPFILES): Add osfsolib.o
* config/alpha/alpha-osf1.mh (MH_CFLAGS): Remove, we can handle
shared libraries now.
* config/alpha/xm-alpha.h: Cleanup, get MAKEVA_* defines right.
* defs.h (CORE_ADDR): Make its type overridable via CORE_ADDR_TYPE,
provide `unsigned int' default.
* breakpoint.c (breakpoint_auto_delete): Delete only if we really
stopped for the breakpoint.
* stabsread.c, stabsread.h (define_symbol): Change valu parameter
to a CORE_ADDR.
* stabsread.c (read_range_type): Handle the case where the lower
bound overflows and the upper doesn't and the range is legal.
* infrun.c (resume): Do not step a breakpoint instruction if
CANNOT_STEP_BREAKPOINT is defined.
* inferior.h (CALL_DUMMY_LOCATION): New variant AT_ENTRY_POINT.
Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
FIX_CALL_DUMMY can be used to set up everything for the dummy.
The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
* infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case. Use
the expected breakpoint pc when setting up the frame for
set_momentary_breakpoint.
* symfile.c (entry_point_address): New function for AT_ENTRY_POINT
support.
* valops.c (call_function_by_hand): Handle AT_ENTRY_POINT case.

cleanups, use new code from Utah.
* (store_inferior_registers): Update to new code from Utah.
* (initialize_kernel_u_addr): Re-enable decl of struct user u.

* hppah-tdep.c: Get rid of gobs of KERNELDEBUG stuff.
* Remove decl of errno, #include wait.h and target.h.
* (frame_saved_pc): Check `flags' pseudo-register to see if we
were inside of a kernel call. If so, then PC is in a different
register. Also, mask out bottom two bits of all PCs so as not to
confuse higher level code.

* (just before step_over_function:): Use stop_func_start, not
stop_pc when checking for the existance of line number info.
stop_func_start will reflect the proper address of the target
routine, not of the stub that we may be traversing to get there.
* tm-hppa.h: define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE
to deal with the stubs that PA compilers sometimes stick between
callers and callees. Also, define FLAGS_REGNUM for access to the
`flags' pseudo-reg.

* (FRAME_FIND_SAVED_REGS): Bug fixes from Utah.
* (PUSH_DUMMY_FRAME, POP_FRAME): Make into real routines in
hppah-nat.c.
* (CALL_DUMMY, FIX_CALL_DUMMY): Fixes from Utah.
* Define struct unwind_table_entry.
* valops.c (call_function_by_hand): Add another arg to

Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
New files.
* Makefile.in: Add new files and dependencies.
* configure.in: Add alpha target.
* config/alpha/alpha-osf1.mh (NATDEPFILES): Add osfsolib.o
* config/alpha/alpha-osf1.mh (MH_CFLAGS): Remove, we can handle
shared libraries now.
* config/alpha/xm-alpha.h: Cleanup, get MAKEVA_* defines right.
* defs.h (CORE_ADDR): Make its type overridable via CORE_ADDR_TYPE,
provide `unsigned int' default.
* breakpoint.c (breakpoint_auto_delete): Delete only if we really
stopped for the breakpoint.
* stabsread.c, stabsread.h (define_symbol): Change valu parameter
to a CORE_ADDR.
* stabsread.c (read_range_type): Handle the case where the lower
bound overflows and the upper doesn't and the range is legal.
* infrun.c (resume): Do not step a breakpoint instruction if
CANNOT_STEP_BREAKPOINT is defined.
* inferior.h (CALL_DUMMY_LOCATION): New variant AT_ENTRY_POINT.
Now that we have the bp_call_dummy breakpoint the call dummy code
is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and

The breakpoint for the dummy is set at the entry point and thats it.
* blockframe.c (inside_entry_file, inside_entry_func): Do not stop
backtraces if pc is in the call dummy at the entry point.
