 emily | overriding for an individual package can be flag driven | 17:59:26 |
| emily | though I think NIX_CFLAGS_COMPILE is probably sufficient interface there | 18:00:02 |
 ris_ | i seeee | 18:02:04 |
| ris_ | yeah i just think it's weird, people will expect that setting hardeningDisable = ["libcxxhardeningfast"]; to actually disable it | 18:02:58 |
| ris_ | * yeah i just think it's weird, people will expect setting hardeningDisable = ["libcxxhardeningfast"]; to actually disable it | 18:47:29 |
| emily | might be good to support hardeningDisable adding flags? but if we control it with the build-time default + cflags maybe it can just be an override in pkgsExtraHardening and not need the hardening* machinery at all | 20:34:31 |

| ris_ | that's interesting - https://hydra.nixos.org/build/319824740 - since 2026-01-22 we've always been able to find pacret instructions in our aarch64 binaries | 22:22:07 |
| ris_ | whether we've got the flag enabled or not | 22:22:30 |
| ris_ | and the weird thing is it's for both clang and gcc | 22:22:47 |
| ris_ | does this correspond to the gcc 15 switch? | 22:26:58 |
| 19 Feb 2026 |
| ris_ | on closer inspection it looks like paciaspis being added to just _init and _fini when "disabled" | 19:16:46 |
| emily | those are hand-written assembly, right? | 19:21:54 |
| ris_ | beyond my understanding | 19:33:47 |
