static build: fix internal locking weaks to get pulled in always

2010-05-07T15:27:39+00:00

Linker is smart and does not pull in weaks.os, ever. This happens
because that compilation unit does not get strong references and
ld eliminates dead code. We really need the weaks for static build
in a compilation unit that is always there, otherwise it won't work.

nptl: fix libc internal, dynamically enabled locking

2010-04-22T15:54:10+00:00

Final iteration to fix libc internal locking if libpthread is pulled
in by dlopen call (directly or indirectly).

We cannot really use the weak symbol trick for shared build, since
the symbols won't get refreshed if libpthread is pulled in dynamically.
In glibc, they have #ifdef SHARED magic to either use pthread_functions
table, or weaks. But as we shared object files with both builds, this
does not sounds good either.

The reintroduces the libc weaks.c, but uses them now only with static
build. For dynamic build, we still use the symbols with same name, but
provide weaks in forward.c so they end up dereferencing the
pthread_functions table indirectly if we are not linked to libpthread.
Mutex initialization is hard coded as inline, as it needs to happen even
if libpthread is not initially loaded.

libc: remove libc weak __pthreads_* wrappers

2010-04-16T17:13:14+00:00

It is not possible to override for libpthread to override
the weak libc definitions. This has never worked in uclibc, and
does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK).

The proper thing to do is have weak prototypes in libc, and
definitions in libpthread only. This way libc runs even if
those functions are not defined, but just needs to protect
against the NULL values (done by implementing __uclibc_maybe_call).

This fix the problems if libc is linked before libpthread or
if libpthread is pulled by a dependency library.
