The new lld linker uses all non-zero offset executable maps. There was a bug when trying to find if the stack is in a signal handler that caused the code to read the wrong place in the elf. Fixed by not adding the elf offset to the relative pc. Also fixed the unwind_for_offline tool to dump multiple stacks if necessary. Added new offline unit test that would have failed with the old code. Bug: 79936827 Test: Ran unit tests and libbacktrace unit tests. Test: Dumped backtraces of system pids. Test: Ran 137-cfi art test. Change-Id: Iaca8c18c2a314902e64c3f72831234297e8dcb1b |
