* nptl: fix Unwind_Resume PLT callsTimo Teräs2010-12-092-7/+15
| | | | | | | | | | My change a49b3a18e463cbe8c94c41501e386e7f4c61609e fixed two Unwind_Resume calls to go via PLT to avoid text relocations for PIC builds. However, it looks the reason for upstream not using PLT calls is that ebx gets clobbered. So we need to reload it.

* nptl: fix x86 assembly PIC relocationsTimo Teräs2010-08-052-2/+2
| | | | | | | | Unwind_Resume needs to be called via PLT. Most calls are already proper, this fix the remaining two problems. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* nptl: mark forwarded functions protectedTimo Teras2010-04-167-0/+7
| | | | | | | | | 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 Teras2010-04-167-7/+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 Teräs2010-04-147-0/+7
| | | | | | | | | | | | | 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.
