Detailed Description

MicroBlaze libdebugger implementation.

Macro Definition Documentation

EXC_FRAME_PRINT

#define EXC_FRAME_PRINT	(		_out,
			_prefix,
			_frame )

Print the exception frame.

Function Documentation

rtems_debugger_target_cache_sync()

int rtems_debugger_target_cache_sync

(

rtems_debugger_target_swbreak *

swbreak

)

Target instruction cache sync. This depends on the target but it normally means a data cache flush and an instruction cache invalidate.

rtems_debugger_target_configure()

int rtems_debugger_target_configure

(

rtems_debugger_target *

target

)

Configure the target. This is architecture specific.

rtems_debugger_target_disable()

int rtems_debugger_target_disable

(

void

)

Disable the target.

rtems_debugger_target_enable()

int rtems_debugger_target_enable

(

void

)

Enable the target.

rtems_debugger_target_exception_print()

void rtems_debugger_target_exception_print

(

CPU_Exception_frame *

frame

)

Print the target exception registers.

rtems_debugger_target_exception_to_signal()

int rtems_debugger_target_exception_to_signal

(

CPU_Exception_frame *

frame

)

Return the signal for the exception.

rtems_debugger_target_frame_pc()

uintptr_t rtems_debugger_target_frame_pc

(

CPU_Exception_frame *

frame

)

Return the frame's program counter (PC).

rtems_debugger_target_hwbreak_control()

int rtems_debugger_target_hwbreak_control	(	rtems_debugger_target_watchpoint	type,
		bool	insert,
		uintptr_t	addr,
		DB_UINT	kind )

Hardware breakpoints.

rtems_debugger_target_hwbreak_insert()

int rtems_debugger_target_hwbreak_insert

(

void

)

Insert hardware breakpoints into the hardware.

rtems_debugger_target_hwbreak_remove()

int rtems_debugger_target_hwbreak_remove

(

void

)

Remove hardware breakpoints from the hardware.

rtems_debugger_target_read_regs()

int rtems_debugger_target_read_regs

(

rtems_debugger_thread *

thread

)

Read the regosters.

rtems_debugger_target_reg_pc()

uintptr_t rtems_debugger_target_reg_pc

(

rtems_debugger_thread *

thread

)

Return the thread's program counter (PC).

rtems_debugger_target_reg_sp()

uintptr_t rtems_debugger_target_reg_sp

(

rtems_debugger_thread *

thread

)

Return the thread's stack pointer (SP).

rtems_debugger_target_tcb_sp()

uintptr_t rtems_debugger_target_tcb_sp

(

rtems_debugger_thread *

thread

)

Return the thread's TCB stack pointer (SP).

rtems_debugger_target_thread_stepping()

int rtems_debugger_target_thread_stepping

(

rtems_debugger_thread *

thread

)

The thread is stepping. Setup the thread to step an instruction.

rtems_debugger_target_write_regs()

int rtems_debugger_target_write_regs

(

rtems_debugger_thread *

thread

)

Write the regosters.
