Compile Rust faster with smarter defaults. Alternative to cargo
build. The default bake compiles more quickly than Cargo's
--release and produces reasonably fast code.
Usage:
sh
$ cargo install cargo-bake
$ cargo bake <other-cargo-build-options>
The default ("normal") bake produces compiler flags more-or-less like
-C opt-level=2
-C inline-threshold=25
-C no-vectorize-loops
-C codegen-units=$NUM_CPUS_UP_TO_4
--link-args=--fuse-ld=gold
-Z no-verify
-C debuginfo=0
Besides the normal bake, cargo-bake also accepts a --fast bake,
which is similar to Cargo's default, a --slow bake, similar to
Cargo's release, and a --glacial bake, which additionally adds LTO.
By default cargo-bake, in all modes, reduces debuginfo generation to
line numbers only. Use the --debug flag to turn on full debuginfo.
Run cargo bake --compare to compare compile time of cargo build
--release to cargo bake.
Note: cargo-bake requires the 2015-11-23 nightlies or later.
