Enum bootstrap::core::config::config::LldMode

source · 
pub enum LldMode {
    Unused,
    SelfContained,
    External,
}
Expand description

LLD in bootstrap works like this:

  • Self-contained lld: use rust-lld from the compiler’s sysroot
  • External: use an external lld binary

It is configured depending on the target:

  1. Everything except MSVC
  • Self-contained: -Clinker-flavor=gnu-lld-cc -Clink-self-contained=+linker
  • External: -Clinker-flavor=gnu-lld-cc
  1. MSVC
  • Self-contained: -Clinker=<path to rust-lld>
  • External: -Clinker=lld

Variants§

§

Unused

Do not use LLD

§

SelfContained

Use rust-lld from the compiler’s sysroot

§

External

Use an externally provided lld binary. Note that the linker name cannot be overridden, the binary has to be named lld and it has to be in $PATH.
