When you say "limitations", I'm not sure what you mean. I wonder if there's a misunderstanding here - the matrix describes the toolchains which are supported out-of-the-box, i.e. build files for them are provided, and they have all been tested and should work.
It's not a matrix of the ONLY platforms which CAN work. Is that what you're thinking? Other platforms might well need the porting abstraction layer to be implemented (the Intel compiler might offer a different set of atomic intrinsics, for example), but that's what it's there for.
- Sir_Cmpwn 10y agoIt's not very clear, then. Reading the page leads me to believe that if x is my toolchain then y won't work, and the idea that such a thing could even be possible for your library speaks very poorly for it. I suggest tweaking it if this is not the case. In any case, I did re-review the library today and I'll still pass on it because I'm very opinionated about C and this library doesn't match my opinions. And I would like to see ARM64 support before I depend on this sort of thing, too, for what it's worth.
- liblfds 10y agoWell, to be fair! the page does say this immediately above the matrix - "The following toolchains and processors are supported out-of-the-box" However, this is certainly not fully explanitative, and of course is just one line immediately above a large and eye-catching matrix. I will change it, to make it more clear, and more eye-catching. Regarding ARM64, it's something I want very much. I will finally have time for it now 7.1.0 is out. I Googled a bit just the other day and there are Pi-like ARM64 dev boards out there now, so I'm going to get one. Which leaves me needing a SPARC dev board, and a POWERPC dev board, and an x86 dev board, and a MIPS64 dev board, and a... :-)

- liblfds 10y agoI hope so. I applied to the GCC compiler farm late last year, but received a reply only after so long a time that I'd deleted the key pair I'd submitted because I thought nothing was going to happen - and my efforts to get back in have yet been unanswered. The GCC compile farm isn't for intensive testing or benchmarking, though (which is what you need for lock-free, to try to catch race conditions) - that test lab sounds more interesting. I have to say though having your own dev boards which are yours and only yours and which you can hammer endlessly is very convenient. It's actually just occurred to me I can leave all the devs boards permanently running the test suite... OTOH, I don't think I can get small, portable dev boards for all the platforms I care about, so at least for some architectures, a third-party farm is probably the only way. Probably the most pressing requirement though is access to a Mac. Right now there are no build files for that platform.
