DESCRIPTION
|

|
|
When gdb starts up the inferior, the kernel maps in the shared
|
|
libraries. We get here with the target stopped at it's first
|
|
instruction, and the libraries already mapped. At this point, this
|
|
function gets called via expansion of the macro
|
|
SOLIB_CREATE_INFERIOR_HOOK.
