Host.cpp was missing Error.h and the implementation of
LaunchProcess. Once againg I have added a "fake" implementation
waiting for a real one.
Fixed the call GetAddressRange to reflect the new interface in
DynamicLoaderLinuxDYLD.cpp.
Added string.h to ARM_DWARF_Registers.cpp that is needed for ::memset.

StoppointLocation.h.
Added a new lldb_private::Address function:
addr_t
Address::GetOpcodeLoadAddress (Target *target) const;
This will strip any special bits from an address to make sure it is suitable
for use in addressing an opcode. Often ARM addresses have an extra bit zero
that can be set to indicate ARM vs Thumb addresses (gotten from return address
registers, or symbol addresses that may be marked up specially). We need to
strip these bits off prior to setting breakpoints, so we can centralized the
place to do this inside the Address class.

Fixed ThreadPlanCallFunction::ReportRegisterState(...) to only dump when
verbose logging is enabled and fixed the function to use the new
RegisterValue method of reading registers.
Fixed the GDB remote client to not send a continue packet after receiving
stdout or stderr from the inferior process.

EDOperandIndexForToken(token) calls fail to return a meaningful operand index,
resulting in both operands and comment being empty. We will use the raw disassembly
string as output in these cases.
There is still a known bug where llvm:tB (A8.6.16 B Encoding T2) is not being processed
as a branch instruction and therefore the symbolic information is not being dumped for
non-raw mode.

types.
Added the abilty to set a RegisterValue type via accessor and enum.
Added the ability to read arguments for a function for ARM if you are on the
first instruction in ABIMacOSX_arm.
Fixed an issue where a file descriptor becoming invalid could cause an
inifnite loop spin in the libedit thread.
llvm-svn: 131610
addr_t
Address::GetCallableLoadAddress (Target *target) const;
This will resolve the load address in the Address object and optionally
decorate the address up to be able to be called. For all non ARM targets, this
just essentially returns the result of "Address::GetLoadAddress (target)". But
for ARM targets, it checks if the address is Thumb, and if so, it returns
an address with bit zero set to indicate a mode switch to Thumb. This is how
we need function pointers to be for return addresses and when resolving
function addresses for the JIT. It is also nice to centralize this in one spot
to avoid having multiple copies of this code.

bool SectionLoadList::ResolveLoadAddress (addr_t load_addr, Address &so_addr) const;
Where if the address is in the last map entry, we need to look it up correctly.
My previous fix was incorrect where it looked in the first if there were
no addresses in the map that were > load_addr. Now we correctly look in the
last entry if our std::map::lower_bound search returns the end of the
collection.

bool
Address::SetLoadAddress (lldb::addr_t load_addr, Target *target);
Added an == and != operator to RegisterValue.
Modified the ThreadPlanTracer to use RegisterValue objects to store the
register values when single stepping. Also modified the output to be a bit
less wide.
Fixed the ABIMacOSX_arm to not overwrite stuff on the stack. Also made the
trivial function call be able to set the ARM/Thumbness of the target
correctly, and also sets the return value ARM/Thumbness.
Fixed the encoding on the arm s0-s31 and d16 - d31 registers when the default
register set from a standard GDB server register sets.

object.__nonzero__(self) is called to implement truth value testing and the built-in operation bool(),
via a simple delegation to self.IsValid().
Change tests under python_api/lldbutil to utilize this mechanism.

all register values. There is some junk that was appearing at the end
of the result the 'g' packet (read all register values). This function
was being called in:
bool
GDBRemoteRegisterContext::ReadAllRegisterValues (lldb::DataBufferSP &data_sp)
Then the packet data for the 'G' packet (write all registers) was being
placed into "data_sp" so the:
bool
GDBRemoteRegisterContext::WriteAllRegisterValues (const lldb::DataBufferSP &data_sp)
could restore it. In attempting to clean up the extra junk at the end of this
packet data, the packet was getting truncated.
llvm-svn: 131468
Modified ClangUserExpression and ClangUtilityFunction to display the actual
error (if one is available) that made the JIT fail instead of a canned
response.
Fixed the restoring of all register values when the 'G' packet doesn't work
to use the correct data.

allocate memory a page at a time for each permission combination and divvy up
the memory and hand it out in 16 byte increments.

give the reason for the interrupt. Also make sure it we don't want to unwind from the evaluation
we print something if it is interrupted.

unambiguous iteration support. So that we could, for example:
...
REGs = lldbutil.get_GPRs(frame)
print "Number of general purpose registers: %d" % len(REGs)
for reg in REGs:
print "%s => %s" %(reg.GetName(), reg.GetValue())
...
llvm-svn: 131418
Prior to this fix we would often call SendPacketAndWaitForResponse() which
returns the number of bytes in the response. The UNSUPPORTED response in the
GDB remote protocol is zero bytes and we were checking for it inside an if
statement:
if (SendPacketAndWaitForResponse(...))
{
if (response.IsUnsupportedResponse())
{
// UNSUPPORTED...
// This will never happen...
}
}
We now handle is properly as:
if (SendPacketAndWaitForResponse(...))
{
}
else
{
// UNSUPPORTED...
}
