Binary size is significant increased from `1.46.0` to `1.51.0` #86610

In Brief

Our project changed the locked rust-toolchain from 1.46.0 to 1.51.0. Then binary size (x86_64-unknown-linux-gnu, release) is significant increased (49 MiB -> 53 MiB, +8.2%).

Details

Size of .strtab section is significant increased

I used cargo build --release to build the same code with rust 1.46.0 and rust 1.51.0.

Then I analyzed the binary with readelf -SW target/release/program.

I got the follow result:

The difference between the .strtab sections

I don't have enough knowledge about compilation.

I just saw the .strtab was increased too much, so I used the follow command to read the .strtab: readelf -p .strtab target/release/program.

I tried compiling tokio-rs/mini-redis with toolchain between 1.45.0 to 1.53.0.

I got the follow table: | Rust Toolchain (x86_64-unknown-linux-gnu) | mini-redis-cli (bytes) | mini-redis-server (bytes) | | |-------------------------------------------|------------------------|---------------------------|----------| | 1.45.0 | 5_773_944 | 6_130_144 | | | 1.46.0 | 5_745_464 | 6_078_856 | Smallest | | 1.47.0 | 6_351_224 | 6_711_960 | | | 1.48.0 | 6_365_384 | 6_711_368 | | | 1.49.0 | 6_358_304 | 6_709_568 | | | 1.50.0 | 6_444_968 | 6_800_512 | | | 1.51.0 | 6_605_840 | 6_985_976 | Biggest | | 1.52.0 | 6_544_608 | 6_909_416 | | | 1.53.0 | 6_420_752 | 6_791_440 | |

From the above table, we could got the follow conclusions:

This seems to be the result of https://github.com/rust-lang/rust/pull/79968 which landed in 1.51. It changes the symbol names of drop_in_place to include which type is actually being dropped. The v0 symbol mangling scheme which we hope to adopt in the near future does the same thing, but also includes generic parameters for all other functions, resulting in even longer symbol names.
