JIT编译器中的SSE和MMX支持 [英] SSE and MMX support in the JIT compiler

问题描述

我想知道是否有人知道JIT编译器是否支持

SSE / SSE2指令？谢谢

Hi,

I was wondering if anyone knows whether the JIT compiler supports
SSE/SSE2 instructions? Thanks

推荐答案

我们目前使用SSE2来解决双重问题对于int cast，它不是用于一般代码的
。

We currently use SSE2 for some things like the double to int cast, it''s not
used for general codegen though.

谢谢David，


有一个我需要问你的问题 - 与v1.0相比，CLR的ver1.1中有相当多的功能/改进吗？我看到

总字节数JIT'在ver1.1中显着减少，而一些

分析显示ver1.1在执行某些
基准测试代码。谢谢

Thanks David,

There''s one thing I need to ask you - were there a fair amount of
features/improvements in ver1.1 of the CLR compared to v1.0? I see that
total numebr of bytes JIT''d are noticeably less in ver1.1 and some
profiling showed that ver1.1 gave better MFLOPs in executing some
benchmarking code. Thanks
