Constants§

  • Flag for the e_flags field in the ELF header indicating a compiled component.
  • Flag for the e_flags field in the ELF header indicating a compiled module.
  • Filler for the os_abi field of the ELF header.
  • This is the name of the section in the final ELF image which contains a concatenated list of all function names.
  • A custom Wasmtime-specific section of our compilation image which stores mapping data from offsets in the image to offset in the original wasm binary.
  • This is the name of the section in the final ELF image that contains the concatenation of all the native DWARF information found in the original wasm files.
  • This is the name of the section in the final ELF image which contains a bincode-encoded CompiledModuleInfo.
  • A custom binary-encoded section of wasmtime compilation artifacts which encodes the ability to map an offset in the text section to the trap code that it corresponds to.
  • A custom section which consists of just 1 byte which is either 0 or 1 as to whether BTI is enabled.
  • This is the name of the section in the final ELF image which contains concatenated data segments from the original wasm module.
  • A bincode-encoded section containing engine-specific metadata used to double-check that an artifact can be loaded into the current host.
  • Flag for the sh_flags field in the ELF text section that indicates that the text section does not itself need to be executable. This is used for the Pulley target, for example, to indicate that it does not need to be made natively executable as it does not contain actual native code.
