n字节对齐 代码

Is large-but-correctly-aligned-and-optimized code than less-bytes-per-instruction/opcode-packed code?

大但正确对齐和优化的代码是否比每个指令/操作码打包的字节少的代码 ？

提到的Alex Ionescu：

code to be “smaller” instead of “faster” though — on modern processors for cases like interrupts and such, large-but-correctly-aligned-and-optimized code is faster than less-bytes-per-instruction/opcode-packed code. 代码“更小”而不是“更快” —在现代处理器上，如中断之类的情况，大但正确对齐和优化的代码比不那么快—每指令字节数/操作码打包代码。

ie:

即：

mov eax, [foo]add eax, 1mov [foo], eax

mov eax, [foo]add eax, 1mov [foo], eax

is faster than

比

inc [foo]
