Re: [PATCH] MIPS32 DSP intrinsics

thanks. :)

So I'm reluctant to allow the code in at this stage as well.  I'm still
happy to review the patch though.  Hopefully then the final version can
be applied soon after the secrecy is lifted.

I don't think it's reasonable to require people to contribute simulator patches in order to check in architecture support. There are lots of GCC ports without (free) simulators.

Similarly, having publicly available ISA manuals should not be a requirement. Sometimes, for example, manuals are written as single documents with ISA documentation mixed in with very proprietary stuff, and it's not reasonable to ask people to split them up. Or, sometimes, people people are reverse-engineering ISAs.

In either case, it's great to encourage these things, but we know that users will want the compiler support, even if these things aren't necessarily available. If there's no simulator or manual, I think it's reasonable to say that it's not your fault if you change something that breaks such a platform; you couldn't reasonably test it. But, simply refusing to accept the code seems like a case of cutting off our noses to spite our faces.
