* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-20243-69253/+0
| | | | | | | | | | | | | This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
* Pull in r374444 from upstream lldb trunk (by me):Dimitry Andric2019-10-102-26/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix process launch failure on FreeBSD after r365761 Summary: After rLLDB365761, and with `LLVM_ENABLE_ABI_BREAKING_CHECKS` enabled, launching any process on FreeBSD crashes lldb with: ``` Expected<T> must be checked before access or destruction. Expected<T> value was in success state. (Note: Expected<T> values in success mode must still be checked prior to being destroyed). ``` This is because `m_operation_thread` and `m_monitor_thread` were wrapped in `llvm::Expected<>`, but this requires the objects to be correctly initialized before accessing them. To fix the crashes, use `llvm::Optional<>` for the members (as indicated by labath), and use local variables to store the return values of `LaunchThread` and `StartMonitoringChildProcess`. Then, only assign to the member variables after checking if the return values indicated success.

| * lldb: shorten thread names to make logs easier to followEd Maste2019-09-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | lldb prepends the thread name to log entries, and the existing thread name for the FreeBSD ProcessMonitor thread was longer than the kernel's supported thread name length, and so was truncated. This made logs hard to read, as the truncated thread name ran into the log message. Shorten "lldb.process.freebsd.operation" to just "freebsd.op" so that logs are more readable. (Upstreaming to lldb still to be done). Notes: svn path=/head/; revision=351662

| * lldb: map TRAP_CAP to a trace trapEd Maste2017-05-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the absense of a more specific handler for TRAP_CAP (generated by ENOTCAPABLE or ECAPMODE while in capability mode) treat it as a trace trap. Example usage (testing the bug in PR219173): % proccontrol -m trapcap lldb usr.bin/hexdump/obj/hexdump -- -Cv -s 1 /bin/ls ... (lldb) run Process 12980 launching Process 12980 launched: '.../usr.bin/hexdump/obj/hexdump' (x86_64) Process 12980 stopped * thread #1, stop reason = trace frame #0: 0x0000004b80c65f1a libc.so.7`__sys_lseek + 10 ... In the future we should have LLDB control the trapcap procctl itself (as it does with ASLR), as well as report a specific stop reason. This change eliminates an assertion failure from LLDB for now.
