Mark Rousskov 4c002fce9d Omit non-needs_drop drop_in_place in vtables ... This replaces the drop_in_place reference with null in vtables. On librustc_driver.so, this drops about ~17k dynamic relocations from the output, since many vtables can now be placed in read-only memory, rather than having a relocated pointer included. This makes a tradeoff by adding a null check at vtable call sites. That's hard to avoid without changing the vtable format (e.g., to use a pc-relative relocation instead of an absolute address, and avoid the dynamic relocation that way). But it seems likely that the check is cheap at runtime.		2024-05-27 16:26:56 -04:00
