Minor change on `struct Symbol` to minimize paddings: 64-bit The problematic areas are: SymInfo (6 bytes) → followed by a 2-byte gap Origin (2 bytes) → followed by a 2-byte gap before StringRef Tags (4 bytes) → followed by a 4-byte gap before SmallVector Flags at the end → 7 bytes end padding 32-bit SymInfo → 2-byte gap Origin → 2-byte gap Flags at the end → 3 bytes end padding current results for the patch f99012b5: clangd version > | 18.1.3 | this branch | this branch @f99012b5 | main @07ff1a63 -- | -- | -- | -- | -- background index | ~2721 MB | ~2972 MB | ~2810 MB | ~2903 MB index cache disk usage | ~184 MB | ~188 MB | ~188 MB | ~187 MB This patch f99012b5 reduces paddings: 64-bit: 240 -> 232 (-8 Bytes, ~3.3%) 32-bit: 144 -> 140 (-4 Bytes, ~2.8%) https://github.com/llvm/llvm-project/pull/170103 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
