* nptl: mark forwarded functions protectedTimo Teras2010-04-168-0/+8
| | | | | | | | | The libc stubs should never override the libpthread provided functions inside libpthread, otherwise the struct pthread_functions that is used by the forwarder stubs goes bad. Signed-off-by: Timo Teras <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* Revert "nptl: mark symbols with libc forwarder hidden"Timo Teras2010-04-168-8/+0
| | | | | | | | | | This reverts most of commit 1610762362e651f86ca284ac59a1d7ec88034e4e. Marking the symbols hidden is wrong, because libc accesses the pthreads internal symbols for internal locking. Signed-off-by: Timo Teras <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* nptl: mark symbols with libc forwarder hiddenTimo Teräs2010-04-148-0/+8
| | | | | | | | | | | | | Add attribute_hidden to all symbols having libc forwarder. This prevents recursive self calls which would happen if libc is before libpthread in linking order: the forwarder functions would call itself via the function table, since the libpthread symbols would get overwritten with libc ones. This has not been a problem in glibc since there these symbols are marked hidden with linker version-script. Since we don't use one, we need to mark these explicitly.

* nptl/sysdeps/unix/sysv/linux/i386: cleanup -DUSE___THREADNatanael Copa2010-04-121-11/+5
| | | | | | | | | | Remove the -DUSE___THREAD from specific assembler files since its used everywhere anyway. This is a cleanup after 447a9d1cc181395c3e2ea77ea88e45dee4b30ce6 Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* nptl/sysdeps/unix/sysv/linux/i386: enable USE___THREAD for assemblerTimo Teräs2010-04-121-0/+1
| | | | | | | | | | | NPTL defines errno as __thread variable. Define USE___THREAD so proper errno assignment is used in assembly files. This fixes segfault while building python.
