From 815994fd17c2f732aacaf273a1e476a62de5f4a6 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Sun, 25 Nov 2012 17:48:11 +0100 Subject: score: Add CPU_Exception_frame Add CPU port type CPU_Exception_frame and function _CPU_Exception_frame_print(). The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh, sparc64, and v850 use an empty default implementation of _CPU_Exception_frame_print(). Add rtems_exception_frame and rtems_exception_frame_print(). Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal() with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc, and sparc for unexpected exceptions. Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the BSP_PRINT_EXCEPTION_CONTEXT define used in the default bsp_fatal_extension(). Add test sptests/spfatal26. --- cpukit/score/cpu/no_cpu/rtems/score/cpu.h | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'cpukit/score/cpu/no_cpu/rtems/score/cpu.h') diff --git a/cpukit/score/cpu/no_cpu/rtems/score/cpu.h b/cpukit/score/cpu/no_cpu/rtems/score/cpu.h index 9ab1f264c8..fe63aea3fc 100644 --- a/cpukit/score/cpu/no_cpu/rtems/score/cpu.h +++ b/cpukit/score/cpu/no_cpu/rtems/score/cpu.h @@ -1263,6 +1263,28 @@ void _CPU_Context_restore_fp( Context_Control_fp **fp_context_ptr ); +/** + * @brief The set of registers that specifies the complete processor state. + * + * The CPU exception frame may be available in fatal error conditions like for + * example illegal opcodes, instruction fetch errors, or data access errors. + * + * @see rtems_fatal(), RTEMS_FATAL_SOURCE_EXCEPTION, and + * rtems_exception_frame_print(). + */ +typedef struct { + uint32_t processor_state_register; + uint32_t integer_registers [1]; + double float_registers [1]; +} CPU_Exception_frame; + +/** + * @brief Prints the exception frame via printk(). + * + * @see rtems_fatal() and RTEMS_FATAL_SOURCE_EXCEPTION. + */ +void _CPU_Exception_frame_print( const CPU_Exception_frame *frame ); + /** * @ingroup CPUEndian * The following routine swaps the endian format of an unsigned int. -- cgit v1.2.3
