Christopher Faylor 62003f180a * exceptions.cc (try_to_debug): Don't use yield() when waiting for another 
process.
(sigpacket::setup_handler): Fix long-standing problem where loop could exit
with lock held.
 2013-06-08 16:54:41 +00:00
Christopher Faylor 1952976a1b * miscfuncs.cc (yield): Revert (after researching) to calling SleepEx with 0. 
We don't want to actually sleep when calling this function.

Christopher Faylor 5d35299e51 * cygwait.cc (cygwait): Remove lock around sig retrieval since this code is 
essentially guarded by thread-specific signal_arrived.
* exceptions.cc (_cygtls::handle_SIGCONT): Simplify.  Eliminate lock/unlock
since code is guarded by signal_arrived.

Will Newton 0d284dd0c1 aarch64: Add support for GNU indirect functions. 
Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests
are ported from the ld-ifunc tests but are enabled for cross builds so can
be run easily without hardware or a simulator.
