; This section defines a series of macros to copy small to medium amounts
; of data from memory to memory, where the size is variable but limited.
;
; The macros are all called as:
; memcpy DST, SRC, SIZE, TMP0, TMP1, XTMP0, XTMP1, XTMP2, XTMP3
; with the parameters defined as:
;    DST     : register: pointer to dst (not modified)
;    SRC     : register: pointer to src (not modified)
;    SIZE    : register: length in bytes (not modified)
;    TMP0    : 64-bit temp GPR (clobbered)
;    TMP1    : 64-bit temp GPR (clobbered)
;    XTMP0   : temp XMM (clobbered)
;    XTMP1   : temp XMM (clobbered)
;    XTMP2   : temp XMM (clobbered)
;    XTMP3   : temp XMM (clobbered)
;
; The name indicates the options. The name is of the form:
; memcpy_<VEC>_<SZ><ZERO><RET>
; where:
; <VEC> is either "sse" or "avx" or "avx2"
; <SZ> is either "64" or "128" and defines largest value of SIZE
; <ZERO> is blank or "_1". If "_1" then the min SIZE is 1 (otherwise 0)
; <RET> is blank or "_ret". If blank, the code falls through. If "ret"
;                           it does a "ret" at the end
;
; For the avx2 versions, the temp XMM registers need to be YMM registers
; If the SZ is 64, then only two YMM temps are needed, i.e. it is called as:
; memcpy_avx2_64 DST, SRC, SIZE, TMP0, TMP1, YTMP0, YTMP1
; memcpy_avx2_128 DST, SRC, SIZE, TMP0, TMP1, YTMP0, YTMP1, YTMP2, YTMP3
;
; For example:
; memcpy_sse_64		: SSE,  0 <= size < 64, falls through
; memcpy_avx_64_1	: AVX1, 1 <= size < 64, falls through
; memcpy_sse_128_ret	: SSE,  0 <= size < 128, ends with ret
; mempcy_avx_128_1_ret	: AVX1, 1 <= size < 128, ends with ret
;
