Since sublevel releases are not ABI compatible we need to adjust
the soname to include the sublevel version.
This makes it possible to install ABI incompatible versions of the
library side by side so clean upgrades are possible.

This patch will convert all the #ifdef USE_TLS and #if USE_TLS to
#if defined(USE_TLS) && USE_TLS.
By checking if the USE_TLS is defined before checking its value will result in
correct behavior for architectures not defining this config symbol.

The TLS merge 534661b91c9849 introduced multiple style problems as well as
random breakage:
- missing _dl_free
- incomplete parametrization of _dl_lookup_hash
- restore FDPIC handling in _dl_lookup_hash

dl_cleanup will call do_dlclose with the handle.
Inside of do_dlclose, the handle will ultimately get free'd.

Since there are more places which want to depend on $(libc), fix them all to
use a new variable $(libc.depend), which contains the filename for which we
have a rule.

doing double negatives

These are mostly the changes necessary to deal with loading the libraries
into memory. A couple new target macros are defined for this purpose, and
the code in dl-elf.c is modified to deal with nommu systems.

Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch.
_dl_find_hash is now a wrapper function around it; unlike on the NPTL branch,
it retains the old interface so that not all callers need to be changed.
_dl_lookup_hash can optionally give its caller a pointer to the module where
the symbol was found.
Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl.
Spelling fixes in the Blackfin port, since Alex Oliva's original version of
these patches used _dl_find_hash_mod as the name of the function rather than
_dl_lookup_hash.

Add the necessary changes in ld.so and libdl to deal with targets that
prepend an underscore to symbol names.
|
|
Add a new function _dl_free. In _dl_malloc, ensure we always get back a full
page from mmap.
Reset _dl_malloc_function and _dl_free_function when libdl is initialized.

- adjust setting flags accordingly to use (hardcoded, see below) -Wl,
Potential improvements:
*) --warn-unresolved-symbols should perhaps be used for all libs
*) eventually rename LDFLAGS to CC_LDFLAGS
*) probe for compiler driver's notion of flag to use for passing in
linker flags (i.e. don't hardcode "-Wl,")

Currently a static libdl.a doesn't run all the constructors or
destructors of the libraries it loads. I can't see a good reason for
that, and it does cause aborts in the destructors it does run for things
like libgcc.so on the Blackfin.
Fixed with the patch below - untested in mainline, but the equivalent
has been in our Blackfin tree for a while now.

Hi All,
the attached patch completes my previous patch on statically linked
application calling dlopen enabling the support for LD_DEBUG.
Further it fixes the missing initialization of the _dl_library_path
variable.
This patch has been fully tested with the uClibc-nptl branch (sh4).
