Could you share those LLVM failures you mentioned too in a new bug and link it here?
I successfully compiled once with USE=-lto and then subsequently compiled successfully with USE=lto. After this I have not been able to build successfully again. All compiles are done using GCC 14.2.1_p20250301. LLVM issue was solely to do with disk space.

Since I have the one successful build of GCC with USE=lto, I used it to compile GCC 15.1.0 twice and did not have any issues. I wish I could get more info on these misaligned planets that seemingly happen only for me and this particular CPU family (Rocket Lake/Tiger Lake).
