* [lldb] Fix lookup of symbols with the same address range but different bindingJan Kratochvil2020-01-131-0/+22

It is due to: Symbol table '.dynsym' contains 2361 entries: Valu e Size Type Bind Vis Name 0000000000022769 5 FUNC LOCAL DEFAULT _nl_load_domain.cold 000000000002276e 0 NOTYPE LOCAL HIDDEN .annobin_abort.c.unlikely ... 000000000002276e 0 NOTYPE LOCAL HIDDEN .annobin_loadmsgcat.c_end.unlikely ... 000000000002276e 0 NOTYPE LOCAL HIDDEN .annobin_textdomain.c_end.unlikely 000000000002276e 548 FUNC GLOBAL DEFAULT abort 000000000002276e 548 FUNC GLOBAL DEFAULT abort@@GLIBC_2.2.5 000000000002276e 548 FUNC LOCAL DEFAULT __GI_abort 0000000000022992 0 NOTYPE LOCAL HIDDEN .annobin_abort.c_end.unlikely GDB has some more complicated preferences between overlapping and/or sharing address symbols, I have made here so far the most simple fix for this case.

* [test] Split LLDB tests into API, Shell & UnitJonas Devlieghere2019-10-092-0/+9
LLDB has three major testing strategies: unit tests, tests that exercise the SB API though dotest.py and what we currently call lit tests. The later is rather confusing as we're now using lit as the driver for all three types of tests. As most of this grew organically, the directory structure in the LLDB repository doesn't really make this clear. The 'lit' tests are part of the root and among these tests there's a Unit and Suite folder for the unit and dotest-tests. This layout makes it impossible to run just the lit tests. This patch changes the directory layout to match the 3 testing strategies, each with their own directory and their own configuration file. This means there are now 3 directories under lit with 3 corresponding targets: - API (check-lldb-api): Test exercising the SB API. - Shell (check-lldb-shell): Test exercising command line utilities. - Unit (check-lldb-unit): Unit tests. Finally, there's still the `check-lldb` target that runs all three test suites. Finally, this also renames the lit folder to `test` to match the LLVM repository layout.
