Hide internal __tdestroy function to allow direct access within libc.so
and libc.a without using GOT nor PLT.
[BZ #18822]
* include/search.h (__tdestroy): Add libc_hidden_proto.
* misc/tsearch.c (__tdestroy): Add libc_hidden_def.
A tsearch red-black tree node contains 3 pointers (key, left, right)
and 1 bit to hold the red-black flag. When allocating new nodes
this 1 bit is expanded to a full word. Causing the overhead per node
to be 3 times the key size.
We can reduce this overhead to just 2 times the key size.
malloc returns naturally aligned memory. All nodes are internally
allocated with malloc and the left/right node pointers are used
as implementation details. So we can use the low bits of the
left/right node pointers to store extra information.
Replace all direct accesses of the struct node_t node pointers and
red-black value with defines that take care of the red-black flag in
the low bit of the (left) node pointer. This reduces the size of the
nodes on 32-bit systems from 16 to 12 bytes and on 64-bit systems
from 32 to 24 bytes.
Also fix a call to CHECK_TREE so the code can be build (and tested)
with DEBUGGING defined again.
V2 changes:
- Add assert after malloc to catch any odd pointers from bad
interposed mallocs.
- Rename implementation flag to USE_MALLOC_LOW_BIT.
ChangeLog:
* misc/tsearch.c (struct node_t): Reduce to 3 pointers if
USE_MALLOC_LOW_BIT. Define pointer/value accessors.
(check_tree_recurse): Use newly defined accessors.
(check_tree): Likewise.
(maybe_split_for_insert): Likewise.
(__tfind): Likewise.
(__tdelete): Likewise.
(trecurse): Likewise.
(tdestroy_recurse): Likewise.
(__tsearch): Likewise. And add asserts for malloc alignment.
(__twalk): Cast root to node in case CHECK_TREE is defined.
This mostly automatically-generated patch converts 113 function
definitions in glibc from old-style K&R to prototype-style. Following
my other recent such patches, this one deals with the case of function
definitions in files that either contain assertions or where grep
suggested they might contain assertions - and thus where it isn't
possible to use a simple object code comparison as a sanity check on
the correctness of the patch, because line numbers are changed.
A few such automatically-generated changes needed to be supplemented
by manual changes for the result to compile. openat64 had a prototype
declaration with "..." but an old-style definition in
sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the
generated prototype in the definition (I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing
such cases in GCC; the old state was undefined behavior not requiring
a diagnostic, but one seems a good idea). In addition, as Florian has
noted regparm attribute mismatches between declaration and definition
are only diagnosed for prototype definitions, and five functions
needed internal_function added to their definitions (in the case of
__pthread_mutex_cond_lock, via the macro definition of
__pthread_mutex_lock) to compile on i386.
After this patch is in, remaining old-style definitions are probably
most readily fixed manually before we can turn on
-Wold-style-definition for all builds.

The sem_* functions bring in references to tdelete, tfind, tsearch and
twalk. But the t* functions are XSI-shaded, while sem_* aren't. This
patch fixes this by using __t* instead, exporting those functions from
libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and
using libc_hidden_* for the benefit of calls within libc.
Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed stripped shared libraries). libpthread gets changes from
PLT reordering; addresses in libc change because of PLT / dynamic
symbol table changes.
