are defined as enumerations. Current bits include:
eEmulateInstructionOptionAutoAdvancePC
eEmulateInstructionOptionIgnoreConditions
Modified the EmulateInstruction class to have a few more pure virtuals that
can help clients understand how many instructions the emulator can handle:
virtual bool
SupportsEmulatingIntructionsOfType (InstructionType inst_type) = 0;
Where instruction types are defined as:
//------------------------------------------------------------------
/// Instruction types
//------------------------------------------------------------------
typedef enum InstructionType
{
eInstructionTypeAny, // Support for any instructions at all (at least one)
eInstructionTypePrologueEpilogue, // All prologue and epilogue instructons that push and pop register values and modify sp/fp
eInstructionTypePCModifying, // Any instruction that modifies the program counter/instruction pointer
eInstructionTypeAll // All instructions of any kind
} InstructionType;
This allows use to tell what an emulator can do and also allows us to request
these abilities when we are finding the plug-in interface.
Added the ability for an EmulateInstruction class to get the register names
for any registers that are part of the emulation. This helps with being able
to dump and log effectively.
The UnwindAssembly class now stores the architecture it was created with in
case it is needed later in the unwinding process.
Added a function that can tell us DWARF register names for ARM that goes
along with the source/Utility/ARM_DWARF_Registers.h file:
source/Utility/ARM_DWARF_Registers.c
Took some of plug-ins out of the lldb_private namespace.
