大家贴一下自己使用的优化参数，好不好
不要emerge info，太长了

-mmmx -msse会导致mozilla产品出现问题。比如在拖拽的时候崩溃。
不是编译mozilla的问题，是使用这个参数编译gtk的问题。

P4处理器！

ldh168

为何我在/etc/make.conf中加入LDFLAGS="-Wl,-O1,--enable-new-dtags"并且执行了env-update &&source /etc/profile后emerge info没有出现这个参数？

Greyhound

我是手动加的:p

ldh168

在编译时才加的？

cnhnln

我发现-mcpu=pentium3 -mmmx -msse -mfpmath=sse不会出现在info里。为什么？是不是因为不是gcc的优化参数的关系？
