-Subject: support setting of default thread stack size via PT_GNU_STACK header
-
-this facilitates building software that assumes a large default stack
-size without any patching to call pthread_setattr_default_np or
-pthread_attr_setstacksize at each thread creation site, using just
-LDFLAGS.
-
-normally the PT_GNU_STACK header is used only to reflect whether
-executable stack is desired, but with GNU ld at least, passing
--Wl,-z,stack-size=N will set a size on the program header. with this
-patch, that size will be incorporated into the default stack size
-(subject to increase-only rule and DEFAULT_STACK_MAX limit).
-
-both static and dynamic linking honor the program header. for dynamic
-linking, all libraries loaded at program start, including preloaded
-ones, are considered. dlopened libraries are not considered, for
-several reasons. extra logic would be needed to defer processing until
-the load of the new library is commited, synchronization woud be
-needed since other threads may be running concurrently, and the
-effectiveness woud be limited since the larger size would not apply to
-threads that already existed at the time of dlopen. programs that will
-dlopen code expecting a large stack need to declare the requirement
-themselves, or pthread_setattr_default_np can be used.
