How to add values from vector to each other

纵饮孤独 提交于 2020-02-07 03:39:25
问题 In my code I solve integral y=x^2-4x+6 I used SSE - it allows me to operate on 4 values in one time. I made program which solve this integral with values from 0 to 5 divided to five 4-element vectors n1, n2, n3, n4. .data n1: .float 0.3125,0.625,0.9375,1.25 n2: .float 1.5625,1.875,2.1875,2.5 n3: .float 2.8125,3.12500,3.4375,3.75 n4: .float 4.0625,4.37500,4.6875,5 szostka: .float 6,6,6,6 czworka: .float 4,4,4,4 .text .global main main: movups (n1),%xmm0 mulps %xmm0,%xmm0 movups (szostka),%xmm2

《JavaScript》JS中的常用方法attr(),splice()

1、jquery中用attr()方法来获取和设置元素属性,attr是attribute(属性)的缩写,在jQuery DOM操作中会经常用到attr(),attr()有4个表达式。   attr( 属性名 ) //获取属性的值(取得第一个匹配元素的属性值。通过这个方法可以方便地从第一个匹配元素中获取一个属性的值。如果元素没有相应属性,则返回 undefined   attr( 属性名, 属性值 ) //设置属性的值 (为所有匹配的元素设置一个属性值。)   attr( 属性名 , 函数值 ) //设置属性的函数值 (为所有匹配的元素设置一个计算的属性值。不提供值,而是提供一个函数,由这个函数计算的值作为属性值。)   attr(properties) //给指定元素设置多个属性值,即:{属性名一: “属性值一” , 属性名二: “属性值二” , … … }。(这是一种在所有匹配元素中批量设置很多属性的最佳方式。 注意,如果你要设置对象的class属性,你必须使用'className' 作为属性名。或者你可以直接使用'class'或者'id'。) 2、数组常用到的方法 array .splice( index , howmany , item1 ,....., itemX ) 来源: https://www.cnblogs.com/-beauTiFul/p/6741835.html

assembly jmp to a line that doesn't exist

怎甘沉沦 提交于 2020-01-25 08:01:05
问题 For the line that says "jmpq *0x400850", there is actually no such line has 0x400850. In this case, since I cannot jump to the place that it is mentioned, do I just skip this command and go to the command that is in the line below? So the answers told me to type "objdump" in terminal, so I typed objdump -d ./bin-lab-ref > output.txt and I got no output in the terminal. What should I do in this situation? 回答1: The instruction jmpq *0x400850(,%rax,8) jumps to the value stored at address

问题 x86 assembly design has instruction suffix, such as l(long) , w(word) , b(byte) . So I thought that jmpl to be long jmp But it worked quite weird when I compile it. See below example. Test1 : assembly main: jmp main Test1 : compile result eb fe jmp 0x0804839b <main> Test2 : assembly main: jmpl main # added l suffix Test2 : Compile result ff 25 9b 83 04 08 jmp *0x0804839b Compared to Test1, Test2 result is unexpected. I think It should be compiled as same as Test1. Question: Is jmpl something
