Well, it's good that someone else has similar feelings, but I feel that Alpha is more of a drag on development than Power or MIPS. I've run into several issues where I'd like to change a system call to be templated to give it more functionality and then I run into the issue of needing to a) keep the old non-templated version around for operating system where I cannot figure out the flags; b) search in dark places on the internet for said flags; c) make up values for said flags to make the compiler stop complaining. I haven't done c) yet with anything other than hacks, but it seems more and more appealing. At least with Linux, I can pull up the source, examine it, and try to reason about what the values for flags will be even if I can't run test programs to verify.
I don't know how anyone could actually use Tru64 or Alpha for research; one eventually needs to compile new applications and that seems like it would require a machine with the Alpha ISA (and Tru64). Cross compiling especially for older architectures is a headache so I'm at a loss as to why anyone would want to even bother with it. -Brandon -----Original Message----- From: gem5-dev [mailto:[email protected]] On Behalf Of Jason Lowe-Power Sent: Monday, October 17, 2016 9:34 AM To: gem5 Developer List <[email protected]> Subject: Re: [gem5-dev] FW: [gem5-users] scons build error for Garnet 2.0 Hi Brandon, We've had this discussion before. See this thread: http://www.mail-archive.com/[email protected]/msg19380.html In summary... I think we're planning on phasing out ALPHA, but that won't happen in the very short term (weeks), but may happen in the medium term (months).
