Notes: Usually one wants to do small reads and write a longword, but -! unfortunately it is difficult in some cases to concatanate bytes -! into a longword on the SH, so this does a longword read and small -! writes. -! -! This implementation makes two assumptions about how it is called: -! -! 1.: If the byte count is nonzero, the address of the last byte to be -! copied is unsigned greater than the address of the first byte to -! be copied. This could be easily swapped for a signed comparison, -! but the algorithm used needs some comparison. -! -! 2.: When there are two or three bytes in the last word of an 11-or-more -! bytes memory chunk to b copied, the rest of the word can be read -! without side effects. -! This could be easily changed by increasing the minumum size of -! a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2, -! however, this would cost a few extra cyles on average. -! For SHmedia, the assumption is that any quadword can be read in its -! enirety if at least one byte is included in the copy. -! - -#include <features.h> - - .section .text..SHmedia32,"ax" - .globl memcpy - .type memcpy, @function - .align 5 - -memcpy: - -#define LDUAQ(P,O,D0,D1) ldlo.q P,O,D0; ldhi.q P,O+7,D1 -#define STUAQ(P,O,D0,D1) stlo.q P,O,D0; sthi.q P,O+7,D1 -#define LDUAL(P,O,D0,D1) ldlo.l P,O,D0; ldhi.l P,O+3,D1 -#define STUAL(P,O,D0,D1) stlo.l P,O,D0; sthi.l P,O+3,D1 - - ld.b r3,0,r63 - pta/l Large,tr0 - movi 25,r0 - bgeu/u r4,r0,tr0 - nsb r4,r0 - shlli r0,5,r0 - movi (L1-L0+63*32 + 1) & 0xffff,r1 - sub r1, r0, r0 -L0: ptrel r0,tr0 - add r2,r4,r5 - ptabs r18,tr1 - add r3,r4,r6 - blink tr0,r63 - -/* Rearranged to make cut2 safe */ - .balign 8 -L4_7: /* 4..7 byte memcpy cntd. */ - stlo.l r2, 0, r0 - or r6, r7, r6 - sthi.l r5, -1, r6 - stlo.l r5, -4, r6 - blink tr1,r63 - - .balign 8 -L1: /* 0 byte memcpy */ - nop - blink tr1,r63 - nop - nop - nop - nop - -L2_3: /* 2 or 3 byte memcpy cntd. */ - st.b r5,-1,r6 - blink tr1,r63 - - /* 1 byte memcpy */ - ld.b r3,0,r0 - st.b r2,0,r0 - blink tr1,r63 - -L8_15: /* 8..15 byte memcpy cntd. */ - stlo.q r2, 0, r0 - or r6, r7, r6 - sthi.q r5, -1, r6 - stlo.q r5, -8, r6 - blink tr1,r63 - - /* 2 or 3 byte memcpy */ - ld.b r3,0,r0 - ld.b r2,0,r63 - ld.b r3,1,r1 - st.b r2,0,r0 - pta/l L2_3,tr0 - ld.b r6,-1,r6 - st.b r2,1,r1 - blink tr0, r63 - - /* 4 .. 7 byte memcpy */ - LDUAL (r3, 0, r0, r1) - pta L4_7, tr0 - ldlo.l r6, -4, r7 - or r0, r1, r0 - sthi.l r2, 3, r0 - ldhi.l r6, -1, r6 - blink tr0, r63 - - /* 8 .. 15 byte memcpy */ - LDUAQ (r3, 0, r0, r1) - pta L8_15, tr0 - ldlo.q r6, -8, r7 - or r0, r1, r0 - sthi.q r2, 7, r0 - ldhi.q r6, -1, r6 - blink tr0, r63 - - /* 16 .. 24 byte memcpy */ - LDUAQ (r3, 0, r0, r1) - LDUAQ (r3, 8, r8, r9) - or r0, r1, r0 - sthi.q r2, 7, r0 - or r8, r9, r8 - sthi.q r2, 15, r8 - ldlo.q r6, -8, r7 - ldhi.q r6, -1, r6 - stlo.q r2, 8, r8 - stlo.q r2, 0, r0 - or r6, r7, r6 - sthi.q r5, -1, r6 - stlo.q r5, -8, r6 - blink tr1,r63 - -Large: - ld.b r2, 0, r63 - pta/l Loop_ua, tr1 - ori r3, -8, r7 - sub r2, r7, r22 - sub r3, r2, r6 - add r2, r4, r5 - ldlo.q r3, 0, r0 - addi r5, -16, r5 - movi 64+8, r27 /* could subtract r7 from that. */ - stlo.q r2, 0, r0 - sthi.q r2, 7, r0 - ldx.q r22, r6, r0 - bgtu/l r27, r4, tr1 - - addi r5, -48, r27 - pta/l Loop_line, tr0 - addi r6, 64, r36 - addi r6, -24, r19 - addi r6, -16, r20 - addi r6, -8, r21 - -Loop_line: - ldx.q r22, r36, r63 - alloco r22, 32 - addi r22, 32, r22 - ldx.q r22, r19, r23 - sthi.q r22, -25, r0 - ldx.q r22, r20, r24 - ldx.q r22, r21, r25 - stlo.q r22, -32, r0 - ldx.q r22, r6, r0 - sthi.q r22, -17, r23 - sthi.q r22, -9, r24 - sthi.q r22, -1, r25 - stlo.q r22, -24, r23 - stlo.q r22, -16, r24 - stlo.q r22, -8, r25 - bgeu r27, r22, tr0 - -Loop_ua: - addi r22, 8, r22 - sthi.q r22, -1, r0 - stlo.q r22, -8, r0 - ldx.q r22, r6, r0 - bgtu/l r5, r22, tr1 - - add r3, r4, r7 - ldlo.q r7, -8, r1 - sthi.q r22, 7, r0 - ldhi.q r7, -1, r7 - ptabs r18,tr1 - stlo.q r22, 0, r0 - or r1, r7, r1 - sthi.q r5, 15, r1 - stlo.q r5, 8, r1 - blink tr1, r63 - - .size memcpy,.-memcpy - -libc_hidden_def(memcpy) diff --git a/libc/string/sh64/memset.S b/libc/string/sh64/memset.S deleted file mode 100644 index 1b8812c..0000000 --- a/libc/string/sh64/memset.S +++ /dev/null @@ -1,97 +0,0 @@ -/* Cloned and hacked for uClibc by Paul Mundt, December 2003 */ -/* Modified by SuperH, Inc.

The R_ARC_NONE relocation is generated when --gc-sections, used by the compile time linker, removes some sections. This is completely normal, and we can see that all other targets (based on random sampling) have support for R_*_NONE relocations (named for each target). Handling R_ARC_NONE involves doing nothing with it, which is nice and easy.
