| 6 | Yay \o/. It's a major change though. Will qa@ write us some docs |
| 7 | on the topic? Landing page: |
| 8 | https://wiki.gentoo.org/wiki/Project:Quality_Assurance#Documentation |
| 9 | |
| 10 | Currently we have scarce mention of PIC-related problems: |
| 11 | https://wiki.gentoo.org/wiki/Hardened/Position_Independent_Code_internals |
| 12 | https://wiki.gentoo.org/wiki/Project:AMD64/Fixing_-fPIC_Errors_Guide |
| 13 | |
| 14 | We will have a bit more more of those problems. Recent example: |
| 15 | https://bugs.gentoo.org/show_bug.cgi?id=618366 |
| 16 | I'm personally interested in how to filter out '-pie' in dosemu. |
| 17 | What is the canonical way to detect '-pie' / '-no-pie' support |
| 18 | in toolchain and flip it? |
| 19 | |
| 20 | A quick poll: |
| 21 | |
| 22 | How about other toolchains? |
| 23 | |
| 24 | A few examples that will have (perhaps minor) troubles doing that: |
| 25 | |
| 26 | - sys-devel/clang will need to be defaulting to pie. llvm@ |
| 27 | llvm is especially touchy as otherwise it's easy to have static library mix. |
| 28 | - dev-lang/ghc will need to be defaulted to pie. haskell@ |
| 29 | - dev-lang/go will need to be defaulted to pie. williamh@ |
| 30 | - dev-lang/ocaml will need to be defaulted to pie. ml@ |
| 31 | - dev-lang/crystal will need to be defaulted to pie. longlene@×××××.com |
| 32 | - others? |
| 33 | |
| 34 | [haskell@ hat on] |
| 35 | We are OK to invest some time and default to pie for dev-lang/ghc |
| 36 | produced binaries. Perhaps slightly after new profiles are introduced |
| 37 | into the tree as it will require merging a few patches upstream. |
