SSE指令的巨集實現
;-------------------------------------------------------------- ;應用此檔案要以masm32軟體包為背景，請更改下 ;邊include語句後的路徑為軟體包中macros.asm的 ;實際路徑，以確保能正確包含進此檔案(請確保你 ;沒有刪除軟體包中的macros.asm)。 ;例如：你的masm32軟體包安裝在E盤根目錄下 ;則應將下邊語句改成include E:\masm32\macros\macros.asm ;使用時在源程式的asm檔案中加入“include 此檔案路徑” ;例如：你將此檔案放在E:\masm32\include目錄下 ;則在原始檔中加入此行語句include E:\masm32\include\MyMacro.inc ;做好這些工作後，就能在源程式中使用SSE3、SSSE3、SSE4.1指令了。 ;例如： ;pshufb xmm(4),MakeXmmword(8080808080808080h,0001020304050607h) ;psrlq xmm(7),16 ;pextrb edx,xmm(5),0 ;■■■■■■■■■■■■■ ;■SSE4.1中有條指令未實現■ ;■■■■■■■■■■■■■
