Scott McMurray	23c8ed14c9	Avoid MIR bloat in inlining ... In 126578 we ended up with more binary size increases than expected. This change attempts to avoid inlining large things into small things, to avoid that kind of increase, in cases when top-down inlining will still be able to do that inlining later.	2024-07-01 05:17:13 -07:00

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

Mark Rousskov	00f4daa276	Codegen const panic messages as function calls ... This skips emitting extra arguments at every callsite (of which there can be many). For a librustc_driver build with overflow checks enabled, this cuts 0.7MB from the resulting binary.	2024-03-22 09:55:50 -04:00
