Christopher Ferris f0c82e7bad Use elf offset in signal step check. ... The function StepIfSignalHandler assumed that the rel_pc passed to it was actually an elf offset. A new version of clang created a libc.so that has a load bias, so tests unwinding through a signal handler would fail on arm. On other ABIs, there is unwind information that could be used instead, so the unwind still worked. The fix is to subtract the load bias from the rel_pc to get an elf offset to pass to the Register StepIfSignalHandler functions. Change all of the Register funtions to make it clear what the first parameter means. Add a unit test for this new code. Also, add an offline test for this case. Bug: 145683525 Test: Ran unit tests using the new clang and the old clang. Change-Id: I3e249653b79bcad6d3a56411a7911fde4888e9d6		2019-12-04 22:29:59 +00:00
