This is our opportunity to set magic flags in the inferior so

that GDB can be notified when a shared library is mapped in and

to tell the dynamic linker that a private copy of the library is

needed (so GDB can set breakpoints in the library).
|

__dld_flags is the location of the magic flags; as of this implementation
|
|

there are 3 flags of interest:
|
|
|
|
|
|
|
|
bit 0 when set indicates that private copies of the libraries are needed
|
|
|
|
bit 1 when set indicates that the callback hook routine is valid
|
|
|
|
bit 2 when set indicates that the dynamic linker should maintain the
|
|
|
|
__dld_list structure when loading/unloading libraries.
|
|
|
|
|
|
|
|
Note that shared libraries are not mapped in at this time, so we have
|
|
|
|
run the inferior until the libraries are mapped in. Typically this
|
|
|
|
means running until the "_start" is called. */
