| olofk | Time to get back to work | 12:04 |
|---|---|---|
| olofk | Getting a lot of GSoC mails | 12:05 |
| olofk | And what the hell is going on with the mailing list? Never seen such intense discussion there ever :) | 12:05 |
| olofk | At least I had time to almost finish integrating the new Wishbone BFM between snowboarding, jacuzzi bathing and six-course dinners :) | 12:06 |
| -!- FreezingAlt is now known as FreezingCold | 12:16 | |
| olofk | Looks like sourceware is moving their CVS repos to git, starting with newlib | 12:46 |
| stekern | wb olofk | 12:56 |
| stekern | yeah, we knew that you were gone, and we know that you get upset if there is too much discussion on irc when you're not here, so we've kept it down. | 12:57 |
| stekern | but it leaked to the mailing list then | 12:57 |
| olofk | Yeah, I missed that loophole | 13:12 |
| olofk | I'm still reading through the mails. | 13:12 |
| olofk | What would happen if there was some malicious program with 50 prefix instructions in a row? Wouldn't that be like a buffer overflow? | 13:13 |
| stekern | yes, but there was a constraint to allow at maximum 2 of them | 13:20 |
| stekern | the rest would be considered nops I suppose | 13:20 |
| stekern | the ones at the end or the ones in the beginning, I don't know | 13:20 |
| olofk | Why two? | 13:21 |
| olofk | For 64-bit? | 13:21 |
| stekern | yes | 13:21 |
| olofk | Not a fan of those prefixies | 13:21 |
| stekern | one nice thing about them is that you can let the linker emit them | 13:22 |
| stekern | since there is no register involved | 13:23 |
| stekern | so your asm (handwritten or compiler generated) would just do: l.ori r3, r0, 0xdeadbeef | 13:24 |
| stekern | but from an implementation point of view I'm not a fan neither (as already stated) ;) | 13:27 |
| stekern | it's a bit like a variable instruction length hack in a fixed instruction length architecture | 13:28 |
| imphil | olofk, oh no! souceware becoming modern? sending zipped patches to a mailing list which then get commited to CVS is such a nice reminder of how ugly the world used to be :) | 13:46 |
| olofk | imphil: They probably just put the CVS repo inside a git repo :) | 14:34 |
| stekern | and then commit the zipped patches ontop of that | 14:44 |
| imphil | I'm sure they'll figure out the most weired way of doing things :) | 14:46 |
