Deal with the inferior unloading shared objects.
* solib.c (current_sos): New function, replacing find_solib.
(find_solib): Deleted.
(free_so): New function.
(clear_solib): Call free_so, instead of writing it out.
(solib_add): Rewritten: compare the inferior's current list of
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.
* objfiles.c (unlink_objfile): Report an internal error if objfile
doesn't occur in the object_files list.
* solib.c (special_symbol_handling): Delete argument; it's not
used.
* solib.c (SOLIB_EXTRACT_ADDRESS): New macro to extract addresses
from solib structures. Use it throughout solib.c, get rid of all
CORE_ADDR casts.
(struct so_list): Change type of lmaddr to CORE_ADDR.
(first_link_map_member): Change return value type to CORE_ADDR,
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.

SYNOPSIS

DESCRIPTION
|
|
|
|
|
|
|
|
Global variable SOLIB_ABSOLUTE_PREFIX is used as a prefix directory
|
|
|
|
to search for shared libraries if they have an absolute path.
|
|
|
|
|
|
|
|
Global variable SOLIB_SEARCH_PATH is used as a prefix directory
|
|
|
|
(or set of directories, as in LD_LIBRARY_PATH) to search for all
|
|
|
|
shared libraries if not found in SOLIB_ABSOLUTE_PREFIX.
|
|
|
|
|
|
|
|
Search order:
|
|
|
|
* If path is absolute, look in SOLIB_ABSOLUTE_PREFIX.
|
2000-12-23 01:27:20 +01:00
|
|
|
* If path is absolute or relative, look for it literally (unmodified).
|
2000-11-21 02:09:54 +01:00
|
|
|
* Look in SOLIB_SEARCH_PATH.
|
|
|
|
* Look in inferior's $PATH.
|
|
|
|
* Look in inferior's $LD_LIBRARY_PATH.

Given a pointer to one of the shared objects in our list
|
|
|
|
of mapped objects, use the recorded name to open a bfd
|
|
|
|
descriptor for the object, build a section table, and then
|
|
|
|
relocate all the section addresses by the base address at
|
|
|
|
which the shared object was mapped.

In most (all?) cases the shared object file name recorded in the

|
|
dynamic linkage tables will be a fully qualified pathname. For
|
|
|

cases where it isn't, do we really mimic the systems search

mechanism correctly in the below code (particularly the tilde

If we notice that the inferior has unloaded some shared objects,

free any symbolic info GDB had read about those shared objects.

Don't load symbolic info for any new shared objects; just add them

SYNOPSIS

DESCRIPTION
|
|
|
|
|
|
|
|
Read in symbolic information for any shared objects whose names
|
|
|
|
match PATTERN. (If we've already read a shared object's symbol
|
|
|
|
info, leave it alone.) If PATTERN is zero, read them all.
|
|
|
|
|
2001-11-01 17:17:08 +01:00
|
|
|
If READSYMS is 0, defer reading symbolic information until later
|
|
|
|
but still do any needed low level processing.
|
|
|
|
|
2000-04-05 22:40:22 +02:00

not a particular address is within the mapped address space of

2000-10-31 00:31:17 +01:00

a shared library.

|
|
|
|
1999-07-07 22:19:36 +02:00
|
|
|
For example, this routine is called at one point to disable
|
|
|
|
breakpoints which are in shared libraries that are not currently
|
|
|
|
mapped in.

/* This function is expected to handle ELF shared libraries. It is

also used on Solaris, which can run either ELF or a.out binaries
|
|
|
|
(for compatibility with SunOS 4), both of which can use shared
|
|
|
|
libraries. So we don't know whether we have an ELF executable or
|
|
|
|
an a.out executable until the user chooses an executable file.
|
|
|
|
|
|
|
|
ELF shared libraries don't get mapped into the address space
|
|
|
|
until after the program starts, so we'd better not try to insert
|
|
|
|
breakpoints in them immediately. We have to wait until the
|
|
|
|
dynamic linker has loaded them; we'll hit a bp_shlib_event
|
|
|
|
breakpoint (look for calls to create_solib_event_breakpoint) when
|
|
|
|
it's ready.
|
|
|
|
|
|
|
|
SunOS shared libraries seem to be different --- they're present
|
|
|
|
as soon as the process begins execution, so there's no need to
|
|
|
|
put off inserting breakpoints. There's also nowhere to put a
|
|
|
|
bp_shlib_event breakpoint, so if we put it off, we'll never get
|
|
|
|
around to it.
|
|
|
|
|
|
|
|
So: disable breakpoints only if we're using ELF shared libs. */
