commit 34d0c99d82791607d96db18b94218269106ef3b8 Author: Louis Dionne <ldionne.2@gmail.com> Date: Thu Oct 3 09:58:11 2024 -0400 [libc++] Stop trying to avoid exporting some typeinfo names (#110925) When the library was initially written, it was not built with hidden visibility. In an attempt to reduce the number of symbols exported from libc++, an explicit list of symbols to avoid exporting was passed to the linker. This was only done on Apple platforms. Since then, the library has moved on in several ways. First, we now build with hidden visibility by default, so arbitrary symbols don't get exported from the library for no reason. Second, we have proper visibility control via source annotations, so we export exactly what we want to, and we do that from the sources. This patch removes the explicit list of symbols to avoid exporting from the library, which at this point doesn't cover much anyways. The only symbols we will now be exporting that we were not before are some typeinfo names for implementation-detail types. While we technically wouldn't have to export those (I don't think any user can get their hands on those typeinfo names), that makes the library more consistent on all platforms. |
