50 The library is tightly integrated with the run-time link editor
51 .Xr ld-elf.so.1 1
62 The run-time linker
63 .Xr ld-elf.so.1 1
64 has some code to ensure backward-compatibility with older versions of
70 .Li -lpthread ,
71 the run-time dependency
83 is more resource-consuming than the previous.
91 First, on SMP systems, a spin loop
99 If the spin loop
103 acquisition attempts as the spin loop,
114 If both the spin and yield loops
119 The kernel wakes up a thread and hands the ownership of the lock to
122 Each thread is provided with a private user-mode stack area
140 kernel for the initial process stack is used for non-initial thread stacks
146 it is kept for backward-compatibility.
148 The size of stacks for threads created by the process at run-time
160 non-initial thread stack size is 2MB for 64bit architectures, and 1MB
162 .Sh RUN-TIME SETTINGS
165 and adjust the operation of the library at run-time:
166 .Bl -tag -width "Ev LIBPTHREAD_SPLITSTACK_MAIN"
181 .Li spin loop
189 A non-zero integer value enables the yield loop
208 .Bl -tag -width "Dv debug.umtx.robust_faults_verbose"
234 .Sh INTERACTION WITH RUN-TIME LINKER
240 stubs for single-threaded processes in
253 The implementation interposes the user-installed
257 entered (libthr-internal) critical sections, where the calling
258 of the user-provided signal handler is unsafe.
266 .Sh PROCESS-SHARED SYNCHRONIZATION OBJECTS
270 user-visible types for all synchronization objects (e.g. pthread_mutex_t)
275 The initial implementation of process-private locking object used this
276 model with internal allocation, and the addition of process-shared objects
279 For process-private objects, the internal structure is allocated using
290 The same allocator is used for thread-specific data, see
294 For process-shared objects, the internal structure is created by first
