Greg Clayton 7ec3d40ec0 Finally tracked down the racy condition that would hose up our debug
sessions: When continue packet has been sent and an interrupt packet was
quickly sent, it would get read at the same time:

$c#00\x03

There was an error where the packet end index was always being computed 
incorrectly by debugserver, but it wouldn't matter if there weren't extra
bytes on the end (the hex \x03 interrupt byte in this case). The first
'$' last 3 bytes of the data in the packet buffer were being trimmed
(trying to trim the '#' + checksum (#XX)) which made:

c#

And this would then be passed to the handle routine for the 'c' packet which
would see an extra character at the end and assume it was going to be in the
form c[addr] where "[addr]" was a hex address to resume at and this would
result in a malformed packet response. This is now fixed and everything works
great.

Another issue was issuing async packets correctly by doing correct handshakes
between the thread that wants to send the async packet, and the thread that
is tracking the current run.

Added a write lock to the communication class as well to make sure you never
get two threads trying to write data at the same time. This wasn't happening,
but it is a good idea to make sure it doesn't.

Greg Clayton 931180e644 Changed the SymbolFile::FindFunction() function calls to only return
lldb_private::Function objects. Previously the SymbolFileSymtab subclass
would return lldb_private::Symbol objects when it was asked to find functions.

The Module::FindFunctions (...) now take a boolean "bool include_symbols" so
that the module can track down functions and symbols, yet functions are found
by the SymbolFile plug-ins (through the SymbolVendor class), and symbols are
gotten through the ObjectFile plug-ins.

Fixed and issue where the DWARF parser might run into incomplete class member
function defintions which would make clang mad when we tried to make certain
member functions with invalid number of parameters (such as an operator=
operator that had no parameters). Now we just avoid and don't complete these
incomplete functions.

Sean Callanan 78e3760fde Updated Clang to a version that supports propagating
the "virtual" flag when importing a C++ function
declaration.  Made changes to LLDB to support other
changes in Clang.

Greg Clayton 645bf5420d Added support for some new environment variables within LLDB to enable some
extra launch options:

LLDB_LAUNCH_FLAG_DISABLE_ASLR disables ASLR for all launched processes

LLDB_LAUNCH_FLAG_DISABLE_STDIO will disable STDIO (reroute to "/dev/null")
for all launched processes

LLDB_LAUNCH_FLAG_LAUNCH_IN_TTY will force all launched processes to be
launched in new terminal windows.

Also, don't init python if we never create a script interpreter.

Jim Ingham 2c36439cb0 Make sure that if a CallFunction thread plan crashes while running in the "run to address" mode, and it
is an auto-discard thread plan, the plan stack unwinds properly.

rdar://problem/8435794
    settings set target.process.output-path does not seem to work

2011-01-25 06:55:13 +00:00
Greg Clayton 4cd178020c Fixed an issue that was stopping LLDB from finding complete definitions for
types. What was happening was the DWARF parser was almost ignoring definitions
(DIEs with the DW_AT_declaration set to 1). It wasn't ignoring declarations
that had _some_ children. When this happened, we would treat the declaration
as a complete type. Often we would have a declaration of a type with just
some enum definitions inside and nothing else. Now we correctly ignore these
definitions, and also I added some changes to allow us to figure out what
decl context these special declarations actually point to.

Jason Molenda f28ce687ac Revert one unintended change checked in to DWARFCallFrameInfo.cpp
with my last commit.

The change should be correct but it's not fixing anything important
and right now unneeded changes are not a good idea.

Sean Callanan 9d2127ad3c Fixed a bug in the expression code which caused
it to interpret a "this" variable that was merely
a pointer -- that is, not a class pointer -- as
meaning that the current context was inside a C++
method.  This bug would prevent expressions from
evaluating correctly in regular C code if there
was a pointer variable named "this" in scope.
