Make writing to files work properly. (Fixes to BFD are also needed.)
* core.c (core_open): Open file ourselves, read or r/w, depending on
write_files. Use bfd_fdopenr.
* gdbcore.h (write_files): New variable.
* exec.c (write_files): Define variable, add set&show for it.
(exec_file_command): Use write_files to open for read or r/write.
Make shared library reading happen automatically. These changes
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
* inferior.h (stop_soon_quietly): Add to exported variables.
* infrun.c (child_create_inferior): call solib hook, if defined.
(child_attach): call solib hook, if defined.
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
(find_solib): Use lookup_misc_func rather than hand-rolled.
(symbol_add_stub): New stub for catch_errors.
(solib_add): Avoid output if !from_tty. Catch errors rather
than just calling symbol_file_add and bombing.
(solib_create_inferior_hook): Interface with the target process
to let it read and alloc shared libs, then figure out what it did.
* core.c (validate_files): Fix typo, soften warning.
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
* utils.c (fputs_demangled): Avoid duplicate printing if
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
(Fix from pierre@la.tce.com (Pierre Willard).)
* main.c (catch_errors): Change argument to a char * from an int,
since a char * can point to a struct full of glop, but an int
is not guaranteed to be able to hold a pointer.
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
breakpoint_re_set_one, breakpoint_re_set): Adapt.
* core.c (core_open, solib_add_stub): Adapt.
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.

|
"top" refer to some section of memory which contains the code for
|
|
|
|
|
|
the call dummy. Calls to this macro assume that the contents of
|
|
|
|
|
|
SP_REGNUM and FP_REGNUM (or the saved values thereof), respectively,
|
|
|
|
|
|
are the things to pass.
|
|
|
|
|
|
|
|
|
|
|
|
This won't work on the 29k, where SP_REGNUM and FP_REGNUM don't
|
|
|
|
|
|
have that meaning, but the 29k doesn't use ON_STACK. This could be
|
|
|
|
|
|
fixed by generalizing this scheme, perhaps by passing in a frame
|
|
|
|
|
|
and adding a few fields, at least on machines which need them for
|
|
|
|
|
|
PC_IN_CALL_DUMMY.
|
|
|
|
|
|
|
|
|
|
|
|
Something simpler, like checking for the stack segment, doesn't work,
|
|
|
|
|
|
since various programs (threads implementations, gcc nested function
|
|
|
|
|
|
stubs, etc) may either allocate stack frames in another segment, or
|
|
|
|
|
|
allocate other kinds of code on the stack. */

/* It's often not enough for our clients to know whether the PC is merely
|

|
|
|
|
somewhere within the call dummy. They may need to know whether the
|
|
|

|
call dummy has actually completed. (For example, wait_for_inferior
|
|
|
|
|
|
wants to know when it should truly stop because the call dummy has
|
|
|
|
|
|
completed. If we're single-stepping because of slow watchpoints,
|
|
|
|
|
|
then we may find ourselves stopped at the entry of the call dummy,
|

and want to continue stepping until we reach the end.)

Note that this macro is intended for targets (like HP-UX) which
|
|
|
|
|
|
require more than a single breakpoint in their call dummies, and
|
|
|
|
|
|
therefore cannot use the CALL_DUMMY_BREAKPOINT_OFFSET mechanism.
|
|
|
|
|
|
|
|
|
|

|
If a target does define CALL_DUMMY_BREAKPOINT_OFFSET, then this
|
|
|
|
|
|
default implementation of CALL_DUMMY_HAS_COMPLETED is sufficient.
|
|
|
|
|
|
Else, a target may wish to supply an implementation that works in
|
|
|
|
|
|
the presense of multiple breakpoints in its call dummy.

This is in order for argument-expansion to occur. E.g.,

(gdb) run *

with some of the catch-fork/catch-exec features we have added.
|

|

|
|
In particular, if the shell does any fork/exec's before

|
the exec of the target program, that can confuse GDB.
