Alex | There can be many good reasons, e.g. "it's a big hack and would negatively impact all other CPUs" | 12:22:54 |
Puna | have you looked at the patches? | 12:23:17 |
K900 | Those are all conditional though? | 12:23:19 |
K900 | Like, all the hacks are ifdef'ed | 12:23:26 |
dramforever | seems like those patches would be conditional on -mcpu=espresso | 12:23:48 |
Alex | So they are. | 12:24:01 |
Marie | I was more worried about if upstream would include such hacks for such specific CPU bugs | 12:25:20 |
Marie | I think I'll ask the author if they have plans for upstreaming | 12:25:36 |
dramforever | gcc does this all the time | 12:25:36 |
K900 | Eh, I'm pretty sure glibc still ships fdiv errata workarounds | 12:25:37 |
K900 | So I don't think this is even particularly bad | 12:25:45 |
dramforever | glibc i haven't checked | 12:25:47 |
Marie | There's also a WIP patch for LLVM afaik | 12:25:55 |
Puna | they definitely care about hacks for exotic hardware | 12:26:27 |
Puna | i was exchanging mails with various GNU projects earlier this year about bugs with the abomination that is double-double long double on powerpc64, and those all got addressed fairly quickly | 12:28:13 |
