Other platforms may benefit from something similar if issues arise. The
libedit library doesn't explicitly initialize the curses termcap library,
which it gets away with until TERM is set to VT100 where it stumbles over
an implementation assumption that may not exist on other platforms.

On Windows we copy python27(_d).dll to the bin directory. We do
this by looking at the PYTHON_LIBRARY specified by the user, which
is something like C:\foo\python27_d.lib, and replacing ".lib" with
".dll". But ".lib" as a regex will also match "flib", etc. So
make this a literal . instead of a wildcard .

When you create a target, it tries to look for the platform's list
of supported architectures for a match. The match it finds can
contain specific triples, like i386-pc-windows-msvc. Later, we
overwrite this value with the most generic triple that can apply
to any platform with COFF support, causing some of the fields of
the triple to get overwritten.
This patch changes the behavior to only merge in values from the COFF
triple if the fields of the matching triple were unknown/unspecified
to begin with.
This fixes load address resolution on Windows, since it enables the
DynamicLoaderWindows to be used instead of DynamicLoaderStatic.

inferring the function signature. This works well where the ABI doesn't
distinguish between variadic and fixed argument lists, but on arm64 the
calling conventions differ. The default assumption works for fixed argument
lists, but variadic functions require explicit prototypes to be called.
By far the most common case where this is an issue is when attempting to use
printf(). This change augments the default expression prefix to include a
working variadic prototype for the function.

CMake FindPythonLibs will look for multiple versions of Python
including both debug and release, and build up a list such as
(debug <debugpath> optimized <optimizedpath>). This confuses
the logic we have in CMake to copy the correct python dll to

To alleviate this, we manually split this list and extract out
the debug and release versions of the python library, and copy
only the correct one to the output directory.

Most of the time, we can use context information just fine to choose a language (i.e. the language of the frame that the root object was defined in, if any); but in some cases, synthetic children may be fabricated as root frame-less entities, and then we wouldn't know any better

We were referring to hardcoded paths /bin/ls and /bin/cat. For
the purposes of this test, the actual value it's set to doesn't
matter, and it might as well be a non-existent path. All that
matters is that the before and after values have to match, and
that trailing whitespace is stripped. On Windows FileSpec
(correctly) converts /bin/ls to D:\bin\ls though, so the before
and after values won't match. So this patch just correctly builds
up a valid path in a platform-agnostic manner, and verifies that
it matches before and after the set.

This is done by adding a "Variable *" to SymbolContext and allowing SymbolFile::ResolveSymbolContext() so if an address is resolved into a symbol context, we can include the global or static variable for that address.
This means you can now find global variables that are merged globals when doing a "image lookup --verbose --address 0x1230000". Previously we would resolve a symbol and show "_MergedGlobals123 + 1234". But now we can show the global variable name.
The eSymbolContextEverything purposely does not include the new eSymbolContextVariable in its lookup since stack frame code does many lookups and we don't want it triggering the global variable lookups.

Also, keep the hit count for the breakpoint in the breakpoint. We were

The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore. Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required. To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them. This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning.
The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines. The new algorithm correctly breaks on the FIRST newline or LAST space/tab before the target column count rather than treating all whitespace interchangeably.
Command interpreters now have the ability to specify help prologue text and a command prefix string. Neither are used in the current LLDB sources but are required to support REPL-like extensions where LLDB commands must be prefixed and additional help text is required to explain how to access traditional debugging commands.

the prologue or not. Both clang and gcc include prologue instructions
but there's no requirement for them to do so -- and I'm sure we'll

I don't have any compilers that omit the prologue instructions so the

With an eh_frame without prologue, this code should reject the
augmentation scheme altogether and we should fall back to using assembly
instruction profiling.
