A kernel call is generally not available, and it would also be slow. Different SH4 variants use different sizes and associativities of the Icache. We use a small bit of dispatch code that can be put hidden in every shared object, which calls the actual processor-specific invalidation code in a separate module. Or if you have operating system support, the OS could mmap the procesor-specific code from a single page, since it is highly repetitive. */ .global GLOBAL(ic_invalidate) HIDDEN_FUNC(GLOBAL(ic_invalidate)) GLOBAL(ic_invalidate): #ifdef __pic__ #ifdef __vxworks mov.l 1f,r1 mov.l 2f,r0 mov.l @r1,r1 mov.l 0f,r2 mov.l @(r0,r1),r0 #else mov.l 1f,r1 mova 1f,r0 mov.l 0f,r2 add r1,r0 #endif mov.l @(r0,r2),r1 #else mov.l 0f,r1 #endif ocbwb @r4 mov.l @(8,r1),r0 sub r1,r4 and r4,r0 add r1,r0 jmp @r0 mov.l @(4,r1),r0 .align 2 #ifndef __pic__ 0: .long GLOBAL(ic_invalidate_array) #else /* __pic__ */ .global GLOBAL(ic_invalidate_array) 0: .long GLOBAL(ic_invalidate_array)@GOT #ifdef __vxworks 1: .long ___GOTT_BASE__ 2: .long ___GOTT_INDEX__ #else 1: .long _GLOBAL_OFFSET_TABLE_ #endif ENDFUNC(GLOBAL(ic_invalidate)) #endif /* __pic__ */ #endif /* SH4 */ #endif /* L_ic_invalidate */ #ifdef L_ic_invalidate_array #if defined(__SH4A__) || (defined (__FORCE_SH4A__) && (defined(__SH4_SINGLE__) || defined(__SH4__) || defined(__SH4_SINGLE_ONLY__) || defined(__SH4_NOFPU__))) .global GLOBAL(ic_invalidate_array) /* This is needed when an SH4 dso with trampolines is used on SH4A. */ .global GLOBAL(ic_invalidate_array) FUNC(GLOBAL(ic_invalidate_array)) GLOBAL(ic_invalidate_array): add r1,r4 synco icbi @r4 rts nop .align 2 .long 0 ENDFUNC(GLOBAL(ic_invalidate_array)) #elif defined(__SH4_SINGLE__) || defined(__SH4__) || defined(__SH4_SINGLE_ONLY__) || defined(__SH4_NOFPU__) .global GLOBAL(ic_invalidate_array) .p2align 5 FUNC(GLOBAL(ic_invalidate_array)) /* This must be aligned to the beginning of a cache line. */ GLOBAL(ic_invalidate_array): #ifndef WAYS #define WAYS 4 #define WAY_SIZE 0x4000 #endif #if WAYS == 1 .rept WAY_SIZE * WAYS / 32 rts nop .rept 7 .long WAY_SIZE - 32 .endr .endr #elif WAYS <= 6 .rept WAY_SIZE * WAYS / 32 braf r0 add #-8,r0 .long WAY_SIZE + 8 .long WAY_SIZE - 32 .rept WAYS-2 braf r0 nop .endr .rept 7 - WAYS rts nop .endr .endr #else /* WAYS > 6 */ /* This variant needs two different pages for mmap-ing. */ .rept WAYS-1 .rept WAY_SIZE / 32 braf r0 nop .long WAY_SIZE .rept 6 .long WAY_SIZE - 32 .endr .endr .endr .rept WAY_SIZE / 32 rts .rept 15 nop .endr .endr #endif /* WAYS */ ENDFUNC(GLOBAL(ic_invalidate_array)) #endif /* SH4 */ #endif /* L_ic_invalidate_array */ #ifdef L_div_table #if defined (__SH2A__) || defined (__SH3__) || defined (__SH3E__) || defined (__SH4__) || defined (__SH4_SINGLE__) || defined (__SH4_SINGLE_ONLY__) || defined (__SH4_NOFPU__) /* This code uses shld, thus is not suitable for SH1 / SH2. */ /* Signed / unsigned division without use of FPU, optimized for SH4.
