实现代码：
<!DOCTYPE html>
<html>
<body>

<h2>汇编代码高亮</h2>

<p id="demo"></p>

<script>
function highlightAssemblyCode(assemblyCode) {
	// 匹配字符串
    var highlighted = assemblyCode.replace(/(".*?"|\'.*?\')/g, '<span style="color: #7f007f;">$1</span>');

    // 匹配指令
    var highlighted = highlighted.replace(/(lea|mov|rep movs|imul|call)/g, '<span style="color: #00007f; font-weight: bold;">$1</span>');

    // 匹配寄存器
    highlighted = highlighted.replace(/(rax|rcx|rdi|rsi|rdx|rbp|eax|ecx)/g, '<span style="color: #46aa03; font-weight: bold;">$1</span>');

    // 匹配十六进制数
    highlighted = highlighted.replace(/(0x[a-fA-F0-9]+|\b[0-9A-Fa-f]+h\b)/g, '<span style="color: #ff0000;">$1</span>');    

    // 匹配方括号和括号
    // highlighted = highlighted.replace(/(\[|\]|\(|\))/g, '<span style="color: #009900; font-weight: bold;">$1</span>');
	
    // 匹配byte ptr
    highlighted = highlighted.replace(/(byte ptr)/g, '<span style="color: #0000ff; font-weight: bold;">$1</span>');
	
	// 添加换行
    highlighted = highlighted.replace(/\n/g, '<br>\n');
	
    return highlighted;
}

var assemblyCode = `lea         rax,[b]
