Raphael Isemann 2a3ef377ec [lldb][NFC] Don't hide a bool in LibCxxOptional's OptionalFrontend::m_size
m_size can only be 1 or 0 and indicates if the optional has a value. Calling
it 'm_size', giving it a size_t data type and then also comparing indices against
'size' is very confusing. Let's just make this a bool.

Jan Kratochvil 1a39f1b966 [lldb] Fix+re-enable Assert StackFrame Recognizer on Linux
D73303 was failing on Fedora Linux and so it was disabled by Skip the
AssertFrameRecognizer test for Linux.

I find no easy way how to find out if it gets recognized as
`__assert_fail` or `__GI___assert_fail` as during `Process` ctor
libc.so.6 is not yet loaded by the debuggee.

DWARF symbol `__GI___assert_fail` overrides the ELF symbol `__assert_fail`.
While external debug info (=DWARF) gets disabled for testsuite (D55859)
that sure does not apply for real world usage.

Raphael Isemann ea2af727a5 [lldb] Refactored TestCallOverriddenMethod.py to general virtual function test
This actually tests all the different situations in which we can call virtual
functions. This removes also all skipIfs as the first skipIf for Linux is
apparently fixed and the second skipIf was just failing due to the constructor
call (which should be its own test and not be tested here).

Jonas Devlieghere 3e70a91963 [lldb/Plugin] Use LLDB_PLUGIN_DECLARE to forward declare plugin initializers
Apparently Linux and Windows have the exact opposite behavior when it
comes to inline declarations of external functions. On Linux they're
considered to be part of the lldb_private namespace, while on Windows
they're considered to be part of the top level namespace. Somehow on
macOS, it doesn't really matter and both are fine...

At this point I don't know what to do, so I'm just adding the
LLDB_PLUGIN_DECLARE macros again as originally proposed in D74245.

Jim Ingham d62a343db2 Add a test for adding and removing Listeners from a BroadcasterManager.
Reid found a bug in removing Listeners from a BroadcasterManager:

https://reviews.llvm.org/D74010

The bug didn't affect the case where there was only one Listener
signed up for a BroadcasterManager, which was all the extant test
case tests.  The driver also only uses one listener (the debugger)
for everything, so neither the test nor anything you do with lldb
command line would have triggered the bug.

This adds a couple more tests using more listeners, and adding and
removing them in a different way, which triggers a separate code path.

Jan Kratochvil cf1046c716 [lldb] Fix+re-enable Assert StackFrame Recognizer on Linux
D73303 was failing on Fedora Linux and so it was disabled by Skip the
AssertFrameRecognizer test for Linux.

On Fedora 30 x86_64 I have:
        $ readelf -Ws /lib64/libc.so.6 |grep '^Symbol\|.*assert_fail'
        Symbol table '.dynsym' contains 2362 entries:
           630: 0000000000030520    70 FUNC    GLOBAL DEFAULT   14 __assert_fail@@GLIBC_2.2.5
        Symbol table '.symtab' contains 22711 entries:
           922: 000000000002275a    15 FUNC    LOCAL  DEFAULT   14 __assert_fail_base.cold
         18044: 0000000000030520    70 FUNC    LOCAL  DEFAULT   14 __GI___assert_fail
         20081: 00000000000303a0   370 FUNC    LOCAL  DEFAULT   14 __assert_fail_base
         21766: 0000000000030520    70 FUNC    GLOBAL DEFAULT   14 __assert_fail

The patch should never expect __GI___assert_fail:

.symtab can be present or not but that should not change that
__assert_fail always wins - it is always present from .dynsym and it can
never be overriden by __GI___assert_fail as __GI___assert_fail has only
local binding. Global binding is preferred since D63540.

External debug info symbols do not matter since D55859 (and DWARF should
never be embedded in system libc.so.6).

Pavel Labath e21b39a86d [lldb] Group ABI plugins
Summary:
There's a fair amount of code duplication between the different ABI plugins for
the same architecture (e.g. ABIMacOSX_arm & ABISysV_arm). Deduplicating this
code is not very easy at the moment because there is no good place where to put
the common code.

Instead of creating more plugins, this patch reduces their number by grouping
similar plugins into a single folder/plugin. This makes it easy to extract
common code to a (e.g.) base class, which can then live in the same folder.

The grouping is done based on the underlying llvm target for that architecture,
because the plugins already require this for their operation.

Med Ismail Bennani 2e005c64f3 [lldb/test] Skip the AssertFrameRecognizer test for Linux
This patch skips the AssertFrameRecognizer test for Linux since it appears to
fail on certain distributions (AFAIK Fedora & ArchLinux).

The failure happen because the thread don't set the current frame to
the most relevant one. So the stopped location doesn't match with what
the test is expecting.

The test will be enabled again after I'll be able to reproduce the failure
on one of those platform and fix the issue.

Med Ismail Bennani 047c4b0369 [lldb/Target] Fix `frame recognizer list` crash when registered with nullptr
One way to register a recognizer is to use RegularExpressionSP for the
module and symbol.

In order to match a symbol regardless of the module, the recognizer can
be registered with a nullptr for the module. However, this cause the
frame recognizer list command to crash because it calls
RegularExpression::GetText without checking if the shared pointer is valid.

This patch adds checks for the symbol and module RegularExpressionSP.

To do so, the StackFrameRecognizer class holds a "Most Relevant Frame" and a
"cooked" stop reason description. When the thread is about to stop, it checks
if the current frame is recognized, and if so, it fetches the recognized frame's
attributes and applies them.
