From 1b404a8b34f6fa80342955cb0a61673503328b51 Mon Sep 17 00:00:00 2001 From: Vladimir Marko Date: Fri, 1 Sep 2017 13:35:26 +0100 Subject: Add debug info for link-time generated thunks. Add debug info for method call thunks (currently unused) and Baker read barrier thunks. Refactor debug info generation for trampolines and record their sizes; change their names to start with upper-case letters, so that they can be easily generated as `#fn_name`. This improved debug info must be generated by `dex2oat -g`, the debug info generated by `oatdump --symbolize` remains the same as before, except for the renamed trampolines and an adjustment for "code delta", i.e. the Thumb mode bit. Cortex-A53 erratum 843419 workaround thunks are not covered by this CL. Test: Manual; run-test --gdb -Xcompiler-option -g 160, pull symbols for gdbclient, break in the introspection entrypoint, check that gdb knows the new symbols (and disassembles them) and `backtrace` works when setting $pc to an address in the thunk.
