+ * Makerules (cpp-srcs-left): When setting this to run
+ cppflags-iterator.mk, must append .c to $(tests) and $(xtests)
+ words. Combine the two loops into one on the concatenated list,
+ including those as well as $(test-srcs).
+
+ * elf/dl-minimal.c (__libc_memalign): Guts of malloc moved here,
+ since we align here with optimally minimal waste anyway.
+ (malloc): Just call that.
+
+ * sysdeps/generic/libc-tls.c (__libc_setup_tls): Set l_tls_offset to
+ the right variable.
+
+ * elf/dl-load.c (_dl_map_object_from_fd): Use p_vaddr, not p_offset,
+ to compute memory location for l_tls_initimage.
+ * elf/rtld.c (_dl_start): Likewise.
+ * sysdeps/generic/libc-tls.c (__libc_setup_tls): Likewise.
+
+ * libio/oldiopopen.c: Move #include's before #if SHLIB_COMPAT,
+ because the .d file is generated in the non-shared case and
+ so fails to catch them otherwise.
+
+ * sysdeps/generic/dl-tls.c (_dl_allocate_tls_storage): New function,
+ split out of _dl_allocate_tls.
+ (_dl_allocate_tls_init): Likewise.
+ (_dl_allocate_tls): Call those.
+ * sysdeps/generic/ldsodefs.h: Declare them with attribute_hidden.
+ * elf/rtld.c (dl_main): Call them separately instead of calling
+ _dl_allocate_tls. Delay _dl_allocate_tls_init until after relocation
+ is finished, so that the initializer data has been relocated before we
+ copy it into the main thread's TLS block.
+
+ * sysdeps/generic/dl-tls.c (_dl_allocate_tls): Fix off-by-one error in
+ loop conditions, prevented the last used module from being initialized.
