Fields

triple: String

Target triple to generate machine code for

The target triple has the general format <arch><sub>-<vendor>-<sys>-<abi>, where:

• <arch> x86, arm, thumb, mips, etc.
• <sub> for example on ARM: v5, v6m, v7a, v7m, etc.
• <vendor> pc, apple, nvidia, ibm, etc.
• <sys> none, linux, win32, darwin, cuda, etc.
• <abi> eabi, gnu, android, macho, elf, etc.

Defaults to $TARGET environment variable, if set (always is in cargo build scripts).

Corresponds to the -mtriple option of llc.

cpu: String

Target CPU to generate machine code for

Default is chosen depending on the target triple.

Corresponds to the -mcpu option of llc.

attr: String

Capabilities of the target code is generated for

Format of this field is the same as the format for -mattr option: +feature enables a feature, -feature disables it. Each feature is delimited by a comma.

Sample string: +sse,+sse2,+sse3,-avx.

Default is chosen depending on the target triple.

Corresponds to the -mattr option of llc.

model: CodegenModel

Code generation

Defaults to CodegenModel::Default.

Corresponds to the -code-model option of llc.

reloc: Relocations

Relocation model

Defaults to Relocations::Default.

Corresponds to the -relocation-model option of llc.

opt: Optimisation

Code optimisation level

Defaults to the same level as specified in the $OPT_LEVEL environment variable (set by cargo) and Optimisation::O0 if not set.

Corresponds to the -O option of llc.

ar_section_name: String

Name of the archive section to insert generated object into
