怎样编译VC中嵌入的PentiumIII汇编指令？

[shyworm]

如movntq和maskmovq指令，编译时出现错误提示：
fatal error C1601: unsupported inline assembly opcode
怎么解决这个问题？

[nbgyf]

_asm
{
}
不行吗？

可能VC不支持！

I don't know!

[shyworm]

_asm
{
...
maskmovq mm1, mm0
...
}

就是这样嵌入的，编译通不过。

#define randasm __asm _emit 0x4A __asm _emit 0x43 __asm _emit 0x4B
.
.
.
__asm {
randasm
}

The _emit Pseudoinstruction
Home | Overview | How Do I

The _emit pseudoinstruction is similar to the DB directive of MASM. You use _emit to define a single immediate byte at the current location in the current text segment. However, _emit can define only one byte at a time, and it can only define bytes in the text segment. It uses the same syntax as the INT instruction.

The following fragment places the given bytes into the code:

#define randasm __asm _emit 0x4A __asm _emit 0x43 __asm _emit 0x4B
.
.
.
__asm {
randasm
}

到Intel网站下载一个试用版。优化到P4都可以。
