inferior program for the lldb debugger to operate on. The fixed lldb executable
corresponds to r142902.
Plus some minor modifications to the test benchmark to conform to way bench.py
is meant to be invoked.

"_cmd", "this", and "self". These variables are handled
differently from all other external variables used by
the expression. Other variables are used indirectly
through the $__lldb_arg operand; only _cmd, this, and
self are passed directly through the ABI.
There are two modifications:
- I added a function to ClangExpressionDeclMap that
retrives the value of one of these variables by name;
and
- I made IRInterpreter fetch these values when needed,
and ensured that the proper level of indirection is
used.

be set if linking against an LLVM compiled with
NDEBUG off. If it is set, we do not enable NDEBUG
in any place where we include LLVM headers.

properly marked as valid.
Also modified the "memory read" command to be able to intelligently repeat
subsequent memory requests, so now you can do:
(lldb) memory read --format hex --count 32 0x1000
Then hit enter to keep viewing the memory that follows the last valid request.

linked against a debug LLVM, runs a variety of
functions -- currently just one -- that verify
that the Decls we create are valid.
ClangASTContext now calls this verifier whenever
it adds a Decl to a DeclContext, and the verifier
checks that the AccessSpecifier is sane.

lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible
Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

types of the same name. If a local variable with the
given name is found (and we are not searching a
specific namespace) we stop right then and there and
report it.

An example (with /Developer/usr/bin/lldb vs. /usr/bin/gdb):
[13:05:04] johnny:/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v +b -n -p TestCompileRunToBreakpointTurnaround.py

parser. Now expression like the following work as
expected:
-
(lldb) expr struct { int a; int b; } $blah = { 10, 20 }
<no result>
(lldb) expr $blah
(<anonymous struct at Parse:6:5>) $blah = {
(int) a = 10
(int) b = 20
}
-
Now the IRForTarget subsystem knows how to handle
static initializers of various composite types.
Also removed an unnecessary parameter from
ClangExpressionDeclMap::GetFunctionInfo.

for debug information that occasionally gets the
const-ness of member functions wrong. We used to
demangle the name, add "const," and remangle it; now
we handle the mangled name directly, which is more
robust.

OptionGroupFormat. Updated OptionGroupFormat to be able to also use the
"--size" and "--count" options. Commands that use a OptionGroupFormat instance
can choose which of the options they want by initializing OptionGroupFormat
accordingly. Clients can either get only the "--format", "--format" + "--size",
or "--format" + "--size" + "--count". This is in preparation for upcoming
chnages where there are alternate ways (GDB format specification) to set a
format.
llvm-svn: 142911
Fixed an issue where bad DWARF from clang would get recycled from DWARF back
into types and cause clang to assert and die, killing the lldb binary, when
it tried to used the type in an expression.

We intend to get rid of this functionality when we rewrite the command
interpreter for streams eventually, but not for now.

command in the '- Hook id' header. This should improve readbility of the 'display'
command if, for example, we have issued 'display a' and 'display b' which turn into
"target stop-hook add -o 'expr -- a'" and "target stop-hook add -o 'expr -- b'".
Plus some minor change in TestAbbreviations.py to conditionalize the platform-specific
checkings of the "image list" output.

A patina of gdb's "display" command, intended mostly for simply monitoring
a variable as you step through source code. Formatters do not work, e.g.
display/x $pc does not work.
