Added files:
lib/libthr/arch/amd64/amd64 _umtx_op_err.S
lib/libthr/arch/i386/i386 _umtx_op_err.S
Log:
Replace function _umtx_op with _umtx_op_err, the later function directly
returns errno, because errno can be mucked by user's signal handler and
most of pthread api heavily depends on errno to be correct, this change
should improve stability of the thread library.
Doesn't this also apply to !i386 & !amd64?
Marcel, you are welcomed to improve it since I only know x86.
Regards,
