O'Keefe. - Michael Widenius; ifdef MC68000 - Updated: 23 April 1984 - Defines: bmove() - - bmove(dst, src, len) moves exactly "len" bytes from the source "src" - to the destination "dst". It does not check for NUL characters as - strncpy() and strnmov() do. Thus if your C compiler doesn't support - structure assignment, you can simulate it with - bmove(&to, &from, sizeof from); - The standard 4.2bsd routine for this purpose is bcopy. But as bcopy - has its first two arguments the other way around you may find this a - bit easier to get right. - No value is returned. - - Note: the "b" routines are there to exploit certain VAX order codes, - but the MOVC3 instruction will only move 65535 characters. The asm - code is presented for your interest and amusement. -*/ - -#include <my_global.h> -#include "m_string.h" - -#if !defined(HAVE_BMOVE) && !defined(bmove) - -#if VaxAsm - -void bmove(dst, src, len) - char *dst, *src; - uint len; - { - asm("movc3 12(ap),*8(ap),*4(ap)"); - } - -#else -#if defined(MC68000) && defined(DS90) - -void bmove(dst, src, len) -char *dst,*src; -uint len; /* 0 <= len <= 65535 */ -{ -asm(" movl 12(a7),d0 "); -asm(" subql #1,d0 "); -asm(" blt .L5 "); -asm(" movl 4(a7),a1 "); -asm(" movl 8(a7),a0 "); -asm(".L4: movb (a0)+,(a1)+ "); -asm(" dbf d0,.L4 "); -asm(".L5: "); -} -#else - -void bmove(dst, src, len) -register char *dst; -register const char *src; -register uint len; -{ - while (len-- != 0) *dst++ = *src++; -} -#endif -#endif -#endif |
