Constants

• EF_WASMTIME_COMPONENT
  Flag for the e_flags field in the ELF header indicating a compiled component.
• EF_WASMTIME_MODULE
  Flag for the e_flags field in the ELF header indicating a compiled module.
• ELFOSABI_WASMTIME
  Filler for the os_abi field of the ELF header.
• ELF_NAME_DATA
  This is the name of the section in the final ELF image which contains a concatenated list of all function names.
• ELF_WASMTIME_ADDRMAP
  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.
• ELF_WASMTIME_DWARF
  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.
• ELF_WASMTIME_INFO
  This is the name of the section in the final ELF image which contains a bincode-encoded CompiledModuleInfo.
• ELF_WASMTIME_TRAPS
  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.
• ELF_WASM_BTI
  A custom section which consists of just 1 byte which is either 0 or 1 as to whether BTI is enabled.
• ELF_WASM_DATA
  This is the name of the section in the final ELF image which contains concatenated data segments from the original wasm module.
• ELF_WASM_ENGINE
  A bincode-encoded section containing engine-specific metadata used to double-check that an artifact can be loaded into the current host.
