SYNOPSIS

|
CORE_ADDR locate_base (void)
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
For both the SunOS and SVR4 shared library implementations, if the
|
|
|
|
inferior executable has been linked dynamically, there is a single
|
|
|
|
address somewhere in the inferior's data space which is the key to
|
|
|
|
locating all of the dynamic linker's runtime structures. This
|
|
|
|
address is the value of the symbol defined by the macro DEBUG_BASE.
|
|
|
|
The job of this function is to find and return that address, or to
|
|
|
|
return 0 if there is no such address (the executable is statically
|
|
|
|
linked for example).
|
|
|
|
|
|
|
|
For SunOS, the job is almost trivial, since the dynamic linker and
|
|
|
|
all of it's structures are statically linked to the executable at
|
|
|
|
link time. Thus the symbol for the address we are looking for has
|
|
|
|
already been added to the minimal symbol table for the executable's
|
|
|
|
objfile at the time the symbol file's symbols were read, and all we
|
|
|
|
have to do is look it up there. Note that we explicitly do NOT want
|
|
|
|
to find the copies in the shared library.
|
|
|
|
|
|
|
|
The SVR4 version is much more complicated because the dynamic linker
|
|
|
|
and it's structures are located in the shared C library, which gets
|
|
|
|
run as the executable's "interpreter" by the kernel. We have to go
|
|
|
|
to a lot more work to discover the address of DEBUG_BASE. Because
|
|
|
|
of this complexity, we cache the value we find and return that value
|
|
|
|
on subsequent invocations. Note there is no copy in the executable
|
|
|
|
symbol tables.
|
|
|
|
|
|
|
|
Irix 5 is basically like SunOS.
|
|
|
|
|
|
|
|
Note that we can assume nothing about the process state at the time
|
|
|
|
we need to find this address. We may be stopped on the first instruc-
|
|
|
|
tion of the interpreter (C shared library), the first instruction of
|
|
|
|
the executable itself, or somewhere else entirely (if we attached
|
|
|
|
to the process for example).

DESCRIPTION
|
|
|
|
|
|
|
|
When gdb starts up the inferior, it nurses it along (through the
|
|
|
|
shell) until it is ready to execute it's first instruction. At this
|
|
|
|
point, this function gets called via expansion of the macro
|
|
|
|
SOLIB_CREATE_INFERIOR_HOOK.
|
|
|
|
|
|
|
|
For SunOS executables, this first instruction is typically the
|
|
|
|
one at "_start", or a similar text label, regardless of whether
|
|
|
|
the executable is statically or dynamically linked. The runtime
|
|
|
|
startup code takes care of dynamically linking in any shared
|
|
|
|
libraries, once gdb allows the inferior to continue.
|
|
|
|
|
|
|
|
For SVR4 executables, this first instruction is either the first
|
|
|
|
instruction in the dynamic linker (for dynamically linked
|
|
|
|
executables) or the instruction at "start" for statically linked
|
|
|
|
executables. For dynamically linked executables, the system
|
|
|
|
first exec's /lib/libc.so.N, which contains the dynamic linker,
|
|
|
|
and starts it running. The dynamic linker maps in any needed
|
|
|
|
shared libraries, maps in the actual user executable, and then
|
|
|
|
jumps to "start" in the user executable.
|
|
|
|
|
|
|
|
For both SunOS shared libraries, and SVR4 shared libraries, we
|
|
|
|
can arrange to cooperate with the dynamic linker to discover the
|
|
|
|
names of shared libraries that are dynamically linked, and the
|
|
|
|
base addresses to which they are linked.
|
|
|
|
|
|
|
|
This function is responsible for discovering those names and
|
|
|
|
addresses, and saving sufficient information about them to allow
|
|
|
|
their symbols to be read at a later time.
|
|
|
|
|
|
|
|
FIXME
|
|
|
|
|
|
|
|
Between enable_break() and disable_break(), this code does not
|
|
|
|
properly handle hitting breakpoints which the user might have
|
|
|
|
set in the startup code or in the dynamic linker itself. Proper
|
|
|
|
handling will probably have to wait until the implementation is
|
|
|
|
changed to use the "breakpoint handler function" method.
|
|
|
|
|
|
|
|
Also, what if child has exit()ed? Must exit loop somehow.

DESCRIPTION
|

|
|
|
|
If no open symbol file, attempt to locate and open the main symbol
|
|
|
|
file. On IRIX, this is the first link map entry. If its name is
|
|
|
|
here, we can open it. Useful when attaching to a process without
|
|
|
|
first loading its symbol file.
|
|
|
|
|
|
|
|
If FROM_TTYP dereferences to a non-zero integer, allow messages to
|
|
|
|
be printed. This parameter is a pointer rather than an int because
|
|
|
|
open_symbol_file_object() is called via catch_errors() and
|
|
|
|
catch_errors() requires a pointer argument. */

SYNOPSIS
|
|
|
|
|
|
|
|
void irix_special_symbol_handling ()
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Once the symbols from a shared object have been loaded in the usual
|
|
|
|
way, we are called to do any system specific symbol handling that
|
|
|
|
is needed.
|
|
|
|
|
|
|
|
For SunOS4, this consisted of grunging around in the dynamic
|
|
|
|
linkers structures to find symbol definitions for "common" symbols
|
|
|
|
and adding them to the minimal symbol table for the runtime common
|
|
|
|
objfile.
|
|
|
|
|
|
|
|
However, for IRIX, there's nothing to do.
