Dawn Perchik a556fe8ec3 [lldb-mi] Fix assignment operator in CMIUtilString
Fix assignment operator in CMIUtilString to not crash the debugger if it
is passed a NULL pointer, which can happen in code like the following:

    SBValue val;
    CMIUtilString s;
    //...
    s = val.GetSummary();

Ilia K b2b0170c0e Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)
Summary:
Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)

This patch cleans up lldb-mi code, and serves to simplify
the following case:
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1).c_str());
```

With CMIUtilString(std::string) we can omit .c_str():
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1));
```

Also, it removes 2 ctors because they aren't needed:
# CMIUtilString::CMIUtilString(const char *const *vpData)
# CMIUtilString::CMIUtilString(const char *vpData, size_t nLen)
and cleans up CMIUtilString::operator=(const std::string &vrRhs).

Bruce Mitchener 40889cd75a [cmake] Build lldb-server on Darwin, set dep on FreeBSD.
Summary:
This switches the decision as to whether or not to lldb-server should
be built to check the same flag that was added that controls whether
or not it is added as a dependency to the 'lldb' target.

It also sets that flag on FreeBSD to maintain parity with the existing
build configuration / situation on FreeBSD.

Todd Fiala 509300d94c cmake fixes for lldb target.
ninja lldb now does the following:
* forces the python post-build step to fire, which sets up the python lldb module properly.
* on Darwin and Linux, requires the lldb-server target to be built.
* on Darwin, requires the debugserver target to be built.

Jason Molenda 9878e3b4b5 A partner to the cleanup in r247741, change the variables names in
debugserver to match.  "gcc" is now "ehframe" and "gdb" is now
"debugserver".  Because this is debugserver, what we call the Process
Plugin register numbers up in lldb are the debugserver register
numbers down here - they are the register numbers that debugserver
will use to refer to these registers over the gdb-remote protocol.

debugserver was already reporting the registers with the key
"ehframe"; this change is just cleaning up the internal variable
names to match.

Jason Molenda 63bd0db071 Clean up register naming conventions inside lldb.
"gcc" register numbers are now correctly referred to as "ehframe"
register numbers.  In almost all cases, ehframe and dwarf register
numbers are identical (the one exception is i386 darwin where ehframe
regnums were incorrect).

The old "gdb" register numbers, which I incorrectly thought were
stabs register numbers, are now referred to as "Process Plugin"
register numbers.  This is the register numbering scheme that the
remote process controller stub (lldb-server, gdbserver, core file
support, kdp server, remote jtag devices, etc) uses to refer to the
registers.  The process plugin register numbers may not be contiguous
- there are remote jtag devices that have gaps in their register
numbering schemes.

I removed all of the enums for "gdb" register numbers that we had
in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM
in all of the register tables for the Process Plugin regnum slot.

This change is almost entirely mechnical; the one actual change in
here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the
qXfer:features:read:target.xml response.  As it parses register
definitions from the xml, it will assign sequential numbers as the
eRegisterKindLLDB numbers (the lldb register numberings must be
sequential, without any gaps) and if the xml file specifies register
numbers, those will be used as the eRegisterKindProcessPlugin
register numbers (and those may have gaps).  A J-Link jtag device's
target.xml does contain a gap in register numbers, and it only 
specifies the register numbers for the registers after that gap.
The device supports many different ARM boards and probably selects
different part of its register file as appropriate.

Bruce Mitchener 7dd8c12d84 [lldb-mi] Clean up CMICmdArgSet usage.
Summary:
CMICmdArgSet stores a vector of non-const pointers to the arguments
that it is validating. It owns them and is responsible for deleting
them.

We don't need to pass a const reference to the argument to
CMICmdArgSet::Add and then take the address and const_cast it
when we can just pass the argument pointer in directly.

This lets us remove some noise at every call site for CMICmdArgSet::Add
and then clean up a couple of bits inside CMICmdArgSet to remove
const_casts.

Summary:
For an array declared like "blk[2][3]", this command was showing:
-data-evaluate-expression blk
^done,value="{[0] = [3], [1] = [3]}"

After this fix, it shows:
-data-evaluate-expression blk
^done,value="{[0] = {[0] = 1, [1] = 2, [2] = 3}, [1] = {[0] = 4, [1] = 5, [2] = 6}}"

So I have just used that and removed the half-baked previous implementation.

1. To handle the expression with spaces, this command uses 2 arguments. For a case
   like -break-condition 1 i == 5, the first will pick the 'i' and second will
   pick the '== 5'. But the second argument was made mandatory which failed in
   cases when there was no space in the expression like i==5.
2. The function GetRestOfExpressionNotSurroundedInQuotes has 2 locals with the
   same names. It resulted in one hiding the other and this function always
   returned empty string.

No regression on Linux. Committed as obvious.

Bruce Mitchener 3921fc7de7 Only export public symbols with the cmake build.
Summary:
This also moves the xcode support files to be near or the same
as the ones used for cmake.

The source/API/liblldb.xcodes.exports differs from the
source/API/liblldb.exports in that one contains the actual
symbol names (_ prefixed) while the other contains the symbol
names as they are in the code. The liblldb.exports file is
preprocessed by the cmake scripts into the correct per-platform
file needed (like a linker script on Linux).

This is not enabled on Windows as Windows doesn't use the same
name mangling and so it won't be valid there. Also, this is handled
already in a different way on Windows (via dll exports).

attach was denied via the System Integrity Protection that

Up in lldb, if we receive the E87 error code, be specific

Also detect the more common case of general attach failure
and print a better error message than "lost connection".

I believe this code will all build on Mac OS X 10.10 systems.
It may not compile or run on earlier versions of the OS.
None of this should build on other non-darwin systems.

Bruce Mitchener b1e77a3642 Fix Mac OS X build, debugserver version handling.
Summary:
No longer rely on cmake to set DEBUGSERVER_VERSION_STR,
but now generate the _vers.c file like xcode does
and include the generated file into the build on Mac OS X.

This fixes the cmake Mac OS X build after an earlier change
by Jason Molenda.
