* misc/Makefile (tests): Add tst-ldbl-error.
HTM state is saved and restore lazily (the state being saved even when the
process actually does not use HTM).
+* The posix_spawn_file_actions_addchdir_np function has been added,
+ enabling posix_spawn and posix_spawnp to run the new process in a
+ different directory. This is a GNU extension and similar to the
+ Solaris function of the same name.
+
Deprecated and removed features, and other changes affecting compatibility:
* The glibc.tune tunable namespace has been renamed to glibc.cpu and the
pread pwrite pread64 pwrite64 \
