Re: Re: Is icedtea support MIPS？

[Ao Qi]

Hi,

Maybe it is because that the jdk was compiled by "gcc
--with-arch=loongson3a", so bin/java includes Loongson 3 instructions.
Loongson did not released a MIPS compatible jdk, although the JIT
generates MIPS compatible instructions when detecting the running CPU
is not a Loongson CPU. Loongson will release MIPS compatible version
jdk in the future.

Before that, if you have a boot jdk, you can build the Loongson
OpenJDK [1] on your machine.

Cheers,
Ao Qi
