 p14 | I took those from source, not build. | 16:55:29 |
 emily | yeah | 16:55:42 |
 sterni | indeed, the question would be if we can just build LLVMgold.so unconditionally or whether it will fail sometimes due to the header | 16:55:43 |
| emily | you do need to adjust the default of the flag that turns it on | 16:55:50 |
| emily | I think that was the intention of the PR | 16:55:53 |
| emily | and p14 just missed that our default is target-specific | 16:55:58 |
| emily | presumably it builds fine on a Darwin host at present as you can do cross to Linux, so I think doing it unconditionally should be okay | 16:56:37 |
| emily | the tar thing is weird but I don't have a better idea | 16:56:44 |
| emily | it should maybe move to libbfd itself | 16:56:51 |
| emily | i.e. libbfd.plugin-api | 16:56:57 |
| emily | so that it is clear what interface we commit to there | 16:57:05 |
| emily | "-DLLVM_BINUTILS_INCDIR=${libbfd.plugin-api}/include" feels nicer | 16:57:38 |
| p14 | Seems a reasonable suggestion! I would appreciate it on-PR so I don’t forget when I come back to it.
With respect to separating LLVMgold.so into a different derivation, I am not sure of the value of that. The build system archania and subsequent potential for breakage required to do it does not seem worth the hassle. | 17:00:05 |
| emily | I don't think that was suggested, was it? | 17:00:19 |
| emily | ah, sterni did | 17:00:35 |
| emily | LLVM hates being split up. the amount of split we already have causes problems | 17:00:45 |
| emily | so I personally wouldn't prioritize that | 17:00:52 |
| emily | I will leave a review. | 17:00:55 |
| p14 | In reply to @emilazy:matrix.org
I will leave a review. Thanks for the review. I think I’ll adjust the scope of the patch by changing the title so that just the target dependence of BFD is dropped. Other fixes can come separately. | 17:35:53 |
| emily | agreed | 17:36:00 |
| emily | didn't want to block the PR on it by any means | 17:36:04 |
| emily | just flagging up that there's still more to do | 17:36:11 |
| p14 | Ack. I may or may not take a closer look, since I am not a darwin user. | 17:36:37 |
| emily | FWIW, the patch applies specifically on Linux | 17:40:26 |
| emily | it's Darwin that opts out, because it breaks stuff for us | 17:40:30 |
| emily | but it's not the right thing on Linux either | 17:40:35 |
| emily | we are injecting -nostdlibinc into every command-line for dubious reasons | 17:40:41 |
| emily | of unwrapped compilers | 17:40:50 |
| emily | we should kill it off for all platforms, one way or another | 17:41:05 |

FWIW, the patch applies specifically on Linux (ok, specifically on not-Darwin) | 17:41:15 |
