Member Function Documentation

clear()

Pool & ttg::detail::MemoryWatchpoint_x86_64::Pool::clear ( void *  addr, const pthread_t *  thread  )

inline

Clear a watchpoint

Parameters

addr	address that is watched
thread	pointer to the pthread_t

Definition at line 143 of file bug.h.

find()

MemoryWatchpoint_x86_64 * ttg::detail::MemoryWatchpoint_x86_64::Pool::find ( void *  addr, const pthread_t *  thread  )

inline

Find watchpoint in thread thread and pointing to addr

Parameters

addr	base address to watch
thread	pointer to the pthread_t

Returns

the pointer to the MemoryWatchpoint object; nullptr if such a watchpoint does not exist

Definition at line 131 of file bug.h.

initialize_instance()

static void ttg::detail::MemoryWatchpoint_x86_64::Pool::initialize_instance ( const std::vector< const pthread_t * > &  threads )

inlinestatic

Constructs the unique pool from a set of thread IDs

Parameters

threads

a vector of pthread_t obtained via pthread_self (for the main thread) and pthread_create for other threads; only pointers to these unique objects can be used in subsequent calls.

Here is the caller graph for this function:

instance()

static std::shared_ptr< Pool > ttg::detail::MemoryWatchpoint_x86_64::Pool::instance ( )

inlinestatic

accesses the unique pool; asserts that the default instance has been initialized by calling initialize()

Definition at line 95 of file bug.h.

Here is the caller graph for this function:

set()

Pool & ttg::detail::MemoryWatchpoint_x86_64::Pool::set ( void *  addr, Size  size, Condition  cond, const pthread_t *  thread  )

inline

Sets a watchpoint in thread thread and pointing to size bytes starting at addr if cond holds

Parameters

addr	base address to watch
size	how many bytes to watch starting at address addr
cond	condition that need to hold to trigger the watchpoint
thread	pthread_t object

Exceptions

std::runtime_error

if setting memory watchpoint failed

Returns

reference to this
