1)支持x64下的内联汇编 2)支持win32下的内联汇编 (2) Linux平台: 默认编译器(gcc) 1)支持32位以及64位的内联汇编,但是需要AT&T格式的内联汇编,且内联汇编基本语法格式为asm(…); 或 asm volatile(…); icc编译器 1)支持32位和64位下的内联汇编。icc编译器支持intel assemly syntax和 GNU-style inline(AT&...
其主要增加了两种保护措施,一是KPP (内核补丁保护),KPP是机制其利用了PG(PatchGuard)技术,PG技术在x64系统下加入了内核哨兵,用于检测系统内核是否被恶意篡改(打补丁),如果发现被打了补丁,则会导致关键结构损毁直接蓝屏,二是DSE (驱动强制签名),DSE技术则是拒绝加载不包含正确签名的驱动。

Inline assembly is not supported on the Itanium and x64 processors. The following topics explain how to use the Visual C/C++ inline assembler with x86 processors:Inline Assembler Overview Advantages of Inline Assembly __asm Using Assembly Language in __asm Blocks Using C or C++ in __...
MSVC does not support inline assembly on the ARM and x64 processors, and only support the form introduced by__asmon x86 processors. When compiling in ISO C mode by GCC or Clang (e.g. with option-std=c11),__asm__must be used instead ofasm. ...
