Update.
* elf/dl-close.c (remove_slotinfo): New function. Handles everything for removing reference of module in slotinfo list. (_dl_close): Use remove_slotinfo. * sysdeps/generic/dl-tls.c: General pretty printing. (oom): Define only if SHARED. (_dl_next_tls_modid): Correct starting point for the case we assume there is a gap. Add missing instruction grouping (doh!). Correct tests for reaching maximum index. * elf/Makefile: Add rules to build and run tst-tls7. * elf/tst-tls7.c: New file. * elf/tst-tlsmod3.c: New file. * elf/tst-tlsmod1.c: Move #include "tls-macros.h" instead #ifdef USE_TLS. * elf/tst-tlsmod2.c: Likewise.
