[lldb] Update header guards to be consistent and compliant with LLVM (NFC)

2020-02-18T07:15:40+00:00

LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch
unifies the header guards across LLDB and converts everything to match
LLVM's style.

[lldb][NFC] Remove unnecessary includes in source/Commands

2019-12-16T07:59:08+00:00

Summary: This removes most of unnecessary includes in the `source/Commands` directory. This was generated by IWYU and a script that fixed all the bogus reports from IWYU. Patch is tested on Linux and macOS.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[Command] Implement `statistics` command.

2018-04-13T18:02:39+00:00

This allows us to collect useful metrics about lldb debugging sessions.

I thought that an example would be better than a thousand words:

  Process 19705 stopped
  * thread #1, queue = 'com.apple.main-thread', stop reason = step in
      frame #0: 0x0000000100000fb4 blah`main at blah.c:3
     1    int main(void) {
     2      int a = 6;
  -> 3      return 0;
     4    }
  (lldb) statistics enable
  (lldb) frame var a
  (int) a = 6
  (lldb) expr a
  (int) $1 = 6
  (lldb) statistics disable
  (lldb) statistics dump
  Number of expr evaluation successes : 1
  Number of expr evaluation failures : 0
  Number of frame var successes : 1
  Number of frame var failures : 0

Future improvements might include:

1. Passing a file, or implementing categories. The way this patch has
been implemented is generic enough to allow this to be extended
easily without breaking the grammar.
2. Adding an SBAPI and Python API for use in scripts.

Thanks to Jim Ingham for discussing the design with me.

[Commands] Add a (currently empty) `stats` command.

2018-03-23T21:55:48+00:00

This one will be used to print statistics about lldb sessions
(including, e.g. number of expression evaluation succeeded or
failed). I decided to commit the skeleton first so that we have
a clean reference on how a command should be implemented.
My future commits are going to populate this command and test
it.
