All of the absolute symbols defined by this module will be present in the final microkernel or nanokernel ELF image (due to the linker's reference to the _OffsetAbsSyms symbol). INTERNAL It is NOT necessary to define the offset for every member of a structure. Typically, only those members that are accessed by assembly language routines are defined; however, it doesn't hurt to define all fields for the sake of completeness. */ #include #include #include /* ARCv2-specific tNANO structure member offsets */ GEN_OFFSET_SYM(tNANO, rirq_sp); GEN_OFFSET_SYM(tNANO, firq_regs); #ifdef CONFIG_ADVANCED_POWER_MANAGEMENT GEN_OFFSET_SYM(tNANO, idle); #endif /* CONFIG_ADVANCED_POWER_MANAGEMENT */ /* ARCv2-specific struct tcs structure member offsets */ GEN_OFFSET_SYM(tTCS, intlock_key); GEN_OFFSET_SYM(tTCS, relinquish_cause); GEN_OFFSET_SYM(tTCS, return_value); #ifdef CONFIG_THREAD_CUSTOM_DATA GEN_OFFSET_SYM(tTCS, custom_data); #endif /* ARCv2-specific IRQ stack frame structure member offsets */ GEN_OFFSET_SYM(tISF, r0); GEN_OFFSET_SYM(tISF, r1); GEN_OFFSET_SYM(tISF, r2); GEN_OFFSET_SYM(tISF, r3); GEN_OFFSET_SYM(tISF, r4); GEN_OFFSET_SYM(tISF, r5); GEN_OFFSET_SYM(tISF, r6); GEN_OFFSET_SYM(tISF, r7); GEN_OFFSET_SYM(tISF, r8); GEN_OFFSET_SYM(tISF, r9); GEN_OFFSET_SYM(tISF, r10); GEN_OFFSET_SYM(tISF, r11); GEN_OFFSET_SYM(tISF, r12); GEN_OFFSET_SYM(tISF, r13); GEN_OFFSET_SYM(tISF, blink); GEN_OFFSET_SYM(tISF, lp_end); GEN_OFFSET_SYM(tISF, lp_start); GEN_OFFSET_SYM(tISF, lp_count); GEN_OFFSET_SYM(tISF, pc); GEN_OFFSET_SYM(tISF, status32); GEN_ABSOLUTE_SYM(__tISF_SIZEOF, sizeof(tISF)); /* ARCv2-specific preempt registers structure member offsets */ GEN_OFFSET_SYM(tPreempt, sp); GEN_ABSOLUTE_SYM(__tPreempt_SIZEOF, sizeof(tPreempt)); /* ARCv2-specific callee-saved stack */ GEN_OFFSET_SYM(tCalleeSaved, r13); GEN_OFFSET_SYM(tCalleeSaved, r14); GEN_OFFSET_SYM(tCalleeSaved, r15); GEN_OFFSET_SYM(tCalleeSaved, r16); GEN_OFFSET_SYM(tCalleeSaved, r17); GEN_OFFSET_SYM(tCalleeSaved, r18); GEN_OFFSET_SYM(tCalleeSaved, r19); GEN_OFFSET_SYM(tCalleeSaved, r20); GEN_OFFSET_SYM(tCalleeSaved, r21); GEN_OFFSET_SYM(tCalleeSaved, r22); GEN_OFFSET_SYM(tCalleeSaved, r23); GEN_OFFSET_SYM(tCalleeSaved, r24); GEN_OFFSET_SYM(tCalleeSaved, r25); GEN_OFFSET_SYM(tCalleeSaved, r26); GEN_OFFSET_SYM(tCalleeSaved, fp); GEN_OFFSET_SYM(tCalleeSaved, r30); GEN_ABSOLUTE_SYM(__tCalleeSaved_SIZEOF, sizeof(tCalleeSaved)); /* ARCv2-specific registers-saved-in-FIRQ structure member offsets */ GEN_OFFSET_SYM(tFirqRegs, lp_count); GEN_OFFSET_SYM(tFirqRegs, lp_start); GEN_OFFSET_SYM(tFirqRegs, lp_end); GEN_ABSOLUTE_SYM(__tFirqRegs_SIZEOF, sizeof(tFirqRegs)); /* size of the struct tcs structure sans save area for floating point regs */ GEN_ABSOLUTE_SYM(__tTCS_NOFLOAT_SIZEOF, sizeof(tTCS)); GEN_ABS_SYM_END
