This change provides __restore/__restore_rt on x86 and __restore_rt on x86_64 with unwinding information to be able to unwind through signal frame via libgcc provided unwinding interface. See comments inlined for more details. Also remove the test that had a dependency on __attribute__((cleanup(foo_cleanup))). It doesn't provide us with any better test coverage than we have from the newer tests, and it doesn't work well across a variety architectures (presumably because no one uses this attribute in the real world). Tested this on host via bionic-unit-tests-run-on-host on both x86 and x86-64. Bug: 17436734 Change-Id: I2f06814e82c8faa732cb4f5648868dc0fd2e5fe4 Signed-off-by: Pavel Chupin <pavel.v.chupin@intel.com>
