cranelift-codegen = { version = "0.107.0", default-features = false, features = ["std", "core", "disas", "trace-log", "unwind", "x86", "arm64", "s390x", "riscv64", "host-arch", "all-arch", "enable-serde", "incremental-cache", "souper-harvest", "isle-errors", "isle-in-source-tree", "timing"] }- default = host-arch, std, timing, unwind
-
These default features are set whenever
cranelift-codegenis added withoutdefault-features = false - std default
-
The "std" feature enables use of libstd. The "core" feature enables use of some minimal std-like replacement libraries. At least one of these two features need to be enabled.
- core
-
The "core" feature used to enable a hashmap workaround, but is now deprecated (we (i) always use hashbrown, and (ii) don't support a no_std build anymore). The feature remains for backward compatibility as a no-op.
- disas = anyhow, capstone
-
Enable the
to_capstonemethod on TargetIsa, for constructing a Capstone context, and thedisassemblemethod onMachBufferFinalized.Affects
isa::TargetIsa.to_capstone… - trace-log
-
Enables detailed logging which can be somewhat expensive.
- unwind default = gimli
-
This enables unwind info generation functionality.
Affects
isa::TargetIsa.map_regalloc_reg_to_dwarf,isa::TargetIsa.emit_unwind_info,isa::TargetIsa.create_systemv_cie,unwind::systemv,unwind::winx64… - x86 all-arch?
-
ISA targets for which we should build.
If no ISA targets are explicitly enabled, the ISA target for the host machine is enabled.Affects
isa::x64… - arm64 all-arch?
-
Affects
isa::aarch64… - s390x all-arch?
- riscv64 all-arch?
-
Affects
isa::riscv64… - host-arch default
-
Enable the ISA target for the host machine
- all-arch = arm64, riscv64, s390x, x86
-
Option to enable all architectures.
- enable-serde incremental-cache? = serde, serde_derive
-
For dependent crates that want to serialize some parts of cranelift
Enables serde of smallvec, enable-serde of cranelift-entity and regalloc2
Affects
buffer::CompilePhase… - incremental-cache = bincode, enable-serde, sha2
-
Enable the incremental compilation cache for hot-reload use cases.
Affects
cranelift-codegen::incremental_cache… - souper-harvest = souper-ir
-
Enable support for the Souper harvester.
- isle-errors build
-
Report any ISLE errors in pretty-printed style.
Enables fancy-errors of cranelift-isle
- isle-in-source-tree
-
Put ISLE generated files in isle_generated_code/, for easier inspection, rather than inside of target/.
- timing default
-
Enable tracking how long passes take in Cranelift.
Enabled by default.
Features from optional dependencies
In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
