2015-06-23xtensa: fix stack frame size for NPTLMax Filippov
Cancellable syscalls use call8 to call functions that enable/disable cancellation, thus they cannot use the default FRAMESIZE. Redefine FRAMESIZE for such syscalls. This fixes the following testsuite failure: .... tst-mqueue8 FAIL tst-mqueue8 got 1 expected 0 going to cancel mq_receive in-time in-time mq_receive cancellation succeeded going to cancel mq_receive early Didn't expect signal from child: got `Segmentation fault' Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

When compiling against the 2.6.18 kernel headers, during linking of the NPTL library it runs into a "undefined reference to PRIVATE_FUTEX" error in pthread_cond_timedwait.S.

2014-04-01Fix warnings in MIPS buildSteve Ellcey
This patch fixes the rest of the set-but-not-used warnings in the MIPS code by using attribute_unused and also fixes some conversion warnings by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp (int type) to __prev (pointer type) generates a warning. Assigning zero to each separately avoids this warning without having to add a cast.

2012-01-13libc: allow to backtrace out of abort callCarmelo Amoroso
Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function.
