+ /* 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. */
