# Tweaking how LLVM is compiled

[llvm]
# Whether to use Rust CI built LLVM instead of locally building it.
#
# Unless you're developing for a target where Rust CI doesn't build a compiler
# toolchain or changing LLVM locally, you probably want to set this to true.
#
# It's currently false by default due to being newly added; please file bugs if
# enabling this did not work for you on Linux (macOS and Windows support is
# coming soon).
#
# We also currently only support this when building LLVM for the build triple.
#
# Note that many of the LLVM options are not currently supported for
# downloading. Currently only the "assertions" option can be toggled.
download-ci-llvm = true

# Indicates whether ccache is used when building LLVM
ccache = true
# or alternatively ...
#ccache = "/path/to/ccache"
# Whether to use Ninja to build LLVM. This runs much faster than make.
ninja = true

# LLVM targets to build support for.
# Note: this is NOT related to Rust compilation targets. However, as Rust is
# dependent on LLVM for code generation, turning targets off here WILL lead to
# the resulting rustc being unable to compile for the disabled architectures.
# Also worth pointing out is that, in case support for new targets are added to
# LLVM, enabling them here doesn't mean Rust is automatically gaining said
# support. You'll need to write a target specification at least, and most
# likely, teach rustc about the C ABI of the target. Get in touch with the
# Rust team and file an issue if you need assistance in porting!

[build]

# Instead of downloading the src/stage0.txt version of Cargo specified, use
# this Cargo binary instead to build all Rust code
cargo = "/home/lzutao/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/cargo"

# Instead of downloading the src/stage0.txt version of the compiler
# specified, use this rustc binary instead as the stage0 snapshot compiler.
rustc = "/home/lzutao/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/rustc"

# Instead of download the src/stage0.txt version of rustfmt specified,
# use this rustfmt binary instead as the stage0 snapshot rustfmt.
#rustfmt = "/path/to/bin/rustfmt"

# Flag to specify whether any documentation is built. If false, rustdoc and
# friends will still be compiled but they will not be used to generate any
# documentation.
#docs = true

# Indicate whether the compiler should be documented in addition to the standard
# library and facade crates.
#compiler-docs = false

# Indicate whether git submodules are managed and updated automatically.
submodules = false

# Indicates that a local rebuild is occurring instead of a full bootstrap,
# essentially skipping stage0 as the local compiler is recompiling itself again.
local-rebuild = true

# Print out how long each rustbuild step took (mostly intended for CI and
# tracking over time)

# =============================================================================
# Options for compiling Rust code itself
# =============================================================================
[rust]
# Whether to always use incremental compilation when building rustc
incremental = true

# debug = true

# Whether or not debug assertions are enabled for the compiler and standard
# library. Debug assertions control the maximum log level used by rustc. When
# enabled calls to `trace!` and `debug!` macros are preserved in the compiled
# binary, otherwise they are omitted.
#
# Defaults to rust.debug value
#debug-assertions = debug

# Whether or not to leave debug! and trace! calls in the rust binary.
# Overrides the `debug-assertions` option, if defined.
#
# Defaults to rust.debug-assertions value
#debug-logging = debug-assertions

# =============================================================================
# Options for specific targets
#
# Each of the following options is scoped to the specific target triple in
# question and is used for determining how to compile each target.
# =============================================================================

# Normally the build system can find LLVM's FileCheck utility, but if
# not, you can specify an explicit file name for it.
