and i386.

This is an example of building the debuggee using both clang and gcc compiers:

or 'self' variable was not properly read if the compiler
optimized it into a register.

Add code to emulate RFE Arm instruction.

Add new instruction context for RFE instruction.

Add several new helper functions to help emulate RFE instruction
(including CurrentModeIsPrivileged, BadMode, and CPSRWriteByInstr).

llvm-svn: 126965

among other things:

// When stopped on breakppint 1, we can get the line entry using SBFrame API
// SBFrame.GetLineEntry().  We'll get the start address for the the line entry
// with the SBAddress type, resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress() in order to get the SBSymbol.
//
// We then stop at breakpoint 2, get the SBFrame, and the the SBFunction object.
//
// The address from calling GetStartAddress() on the symbol and the function
// should point to the same address, and we also verify that.

And add one utility function disassemble(target, function_or_symbol) to lldbutil.py:

    """Disassemble the function or symbol given a target.

    It returns the disassembly content in a string object.
    """

TestDisasm.py uses the disassemble() function to do disassembly on the SBSymbol, and
then the SBFunction object.

// When stopped on breakppint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry().  We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.


Add two utility functions to lldbutil.py:

o get_stopped_threads(process, reason):

  return the list of threads with the specified stop reason or an empty list if not found

o get_stopped_thread(process, reason):

  return the first thread with the given stop reason or None if not found

Fix bug where bitwise-AND was being used and it should have been bitwise-OR.

llvm-svn: 126904

Add code to emulate ADD (immediate, Thumb) Arm instruction.

Add addition context to EmulateInstruction contexts.

llvm-svn: 126903

and symbols, and also allow clients to get the prologue size in bytes:

    SBAddress
    SBFunction::GetStartAddress ();
    
    SBAddress
    SBFunction::GetEndAddress ();
    
    uint32_t
    SBFunction::GetPrologueByteSize ();

    SBAddress
    SBSymbol::GetStartAddress ();
    
    SBAddress
    SBSymbol::GetEndAddress ();
    
    uint32_t
    SBSymbol::GetPrologueByteSize ();

llvm-svn: 126892

Add code to emulate MUL Arm instruction.

Add new context type & info structure for  mul instruction.

llvm-svn: 126891

anything in a SBSymbolContext filled in given an SBAddress:

SBSymbolContext
SBTarget::ResolveSymbolContextForAddress (const SBAddress& addr, uint32_t resolve_scope);

Also did a little cleanup on the ProcessGDBRemote stdio file handle
code.

o int_to_bytearray()
o bytearray_to_int()

They return/interpret the bytearray in the little endian format.
For big endian, simply perform ba.reverse() on the bytearray object.

And modify TestProcessAPI.py to take advantage of the functions.

llvm-svn: 126813

Add code to emulate LDRSB (register) Arm instruction.

among other SBProcess APIs, to write (int)256 into a memory location of a global variable
(int)my_int and reads/checks the variable afterwards.

Add code to emulate LDRH (register) Arm instruction.

llvm-svn: 126758

the SBProcess.ReadMemory() API, which, due to SWIG typemap'ing, expects 3 arguments (the location
to read from, the size in bytes to read, and an SBError object), and returns the result as a
Python string object.

On SnowLeopard where this has been tested, the SWIG script needs to be pampered (use the exact
same parameter names as in SBProcess.h) in order for this to work.
