Hello- Here is an upated patch series. Most of the patches have not changed from v1.
v1 thread: https://gcc.gnu.org/pipermail/gcc-patches/2024-November/667333.html The changes are: - As Richard suggested, I changed to make the feature not configurable, since it will be too hard to optimize structure packing without committing to the size of location_t. In v1, the first patch of the series added the support and the last patch in the series added the configure option. Now, the first patch lays the groundwork in libcpp to make the size of location_t easy to adjust, and the last patch in the series actually changes it. This way, the series could still be committed as all separate patches without creating any invalid intermediate states. - Two of the v1 patches were acked by Jason. One of those (v1 05/15) has already been pushed as r15-5067 and does not appear in v2. The other one (v1 10/15) has changed very slightly in v2 and is now v2 09/14. The only change is the #ifdef on the former configure option has been replaced with a check on sizeof(location_t) instead, since the configure option is no longer in use. - There was some discussion on the idea of the patches that I took to indicate general support for moving in this direction. I did not yet receive any specific feedback on the rest of the patches.
