/* This module implements a sort of half target that sits between the
|
|
|
|
|
machine-independent parts of GDB and the ptrace interface (infptrace.c) to
|
|
|
|
|
provide access to the HPUX user-mode thread implementation.
|
|
|
|
|
|
|
|
|
|
HPUX threads are true user-mode threads, which are invoked via the cma_*
|
|
|
|
|
and pthread_* (DCE and Posix respectivly) interfaces. These are mostly
|
|
|
|
|
implemented in user-space, with all thread context kept in various
|
|
|
|
|
structures that live in the user's heap. For the most part, the kernel has
|
|
|
|
|
no knowlege of these threads.
