The 67** state that is saved in the CPU-specific segment includes GPRs, 68** FPRs, IPRs, halt code, MCHK flag, etc. All other state is saved 69** in the platform-specific segment. 70** 71** The impure pointer will need to be adjusted by a different offset 72** value for each region within a given segment. The SAVE and RESTORE 73** macros will auto-magically adjust the offsets accordingly. 74** 75*/ 76#if 0 77#define SAVE_GPR(reg,offset,base) \ 78 stq_p reg, ((offset-0x200)&0x3FF)(base) 79 80#define RESTORE_GPR(reg,offset,base) \ 81 ldq_p reg, ((offset-0x200)&0x3FF)(base) 82 83 84#define SAVE_FPR(reg,offset,base) \ 85 stt reg, ((offset-0x200)&0x3FF)(base) 86 87#define RESTORE_FPR(reg,offset,base) \ 88 ldt reg, ((offset-0x200)&0x3FF)(base) 89 90#define SAVE_IPR(reg,offset,base) \ 91 mfpr v0, reg; \ 92 stq_p v0, ((offset-CNS_Q_IPR)&0x3FF)(base) 93 94#define RESTORE_IPR(reg,offset,base) \ 95 ldq_p v0, ((offset-CNS_Q_IPR)&0x3FF)(base); \ 96 mtpr v0, reg 97 98#define SAVE_SHADOW(reg,offset,base) \ 99 stq_p reg, ((offset-CNS_Q_IPR)&0x3FF)(base) 100 101#define RESTORE_SHADOW(reg,offset,base)\ 102 ldq_p reg, ((offset-CNS_Q_IPR)&0x3FF)(base) 103#else 104//#define SEXT10(X) (((X) & 0x200) ?
