_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to setup the thread private area of all new threads. ld.elf_so is responsible for setting up the private area for the initial thread. Similar functions are called from _libc_init for static binaries, using dl_iterate_phdr to access the ELF Program Header. Add test cases to exercise the different TLS storage models. Test cases are compiled and installed on all platforms, but are skipped on platforms not marked for TLS support. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger. It is inspired by the TLS support in FreeBSD by Doug Rabson and the clean ups of the DragonFly port of the original FreeBSD modifications.

# All library objects contain sccsid strings by default; they may be
|
|
# excluded as a space-saving measure. To produce a library that does
|
|
# not contain these strings, delete -DLIBC_SCCS and -DSYSLIBC_SCCS
|
|
# from CPPFLAGS below. To remove these strings from just the system call
|
|
# stubs, remove just -DSYSLIBC_SCCS from CPPFLAGS.

# The NLS (message catalog) functions are always in libc. To choose that
|
|
# strerror(), perror(), strsignal(), psignal(), etc. actually call the NLS
|
|
# functions, put -DNLS on the CPPFLAGS line below.
|
|
#
|
|
# The YP functions are always in libc. To choose that getpwent() and friends
|
|
# actually call the YP functions, put -DYP on the CPPFLAGS line below.

# The Hesiod functions are always in libc. To choose that getpwent() and friends
|

# actually call the Hesiod functions, put -DHESIOD on the CPPFLAGS line below.
