Functions ¶
func LoadCodeSection ¶ added in v0.5.0
func LoadCodeSection(config *CodeConfig, r Reader, mod *Module) (err error)
LoadCodeSection reads a WebAssembly module's code section and generates machine code and read-only data.
func LoadDataSection ¶ added in v0.5.0
func LoadDataSection(config *DataConfig, r Reader, mod *Module) (err error)
LoadDataSection reads a WebAssembly module's data section and generates initial contents of mutable program state (globals and linear memory).
func LoadUnknownSections ¶ added in v0.5.0
LoadUnknownSections reads a WebAssembly module's extension sections which follow known sections.
Types ¶
type CodeBuffer ¶ added in v0.5.0
type CodeConfig ¶ added in v0.5.0
type CodeConfig struct {
EntrySymbol string
EntryArgs []uint64
Text CodeBuffer // Initialized with default implementation if nil.
ROData DataBuffer // Initialized with default implementation if nil.
RODataAddr uintptr
ObjectMapper ObjectMap
EventHandler func(event.Event)
Config
}
CodeConfig for a single compiler invocation.
type DataBuffer ¶
type DataConfig ¶ added in v0.5.0
type DataConfig struct {
GlobalsMemory DataBuffer // Initialized with default implementation if nil.
MemoryAlignment int // Initialized with minimal value if zero.
Config
}
DataConfig for a single compiler invocation.
type ImportResolver ¶ added in v0.5.0
type ImportResolver interface {
ResolveFunc(module, field string, sig wa.FuncType) (addr uint64, err error)
ResolveGlobal(module, field string, t wa.Type) (init uint64, err error)
}
ImportResolver maps symbols to function addresses and constant values.
type Module ¶
type Module struct {
// contains filtered or unexported fields
}
Module contains a WebAssembly module specification without code or data.
func LoadInitialSections ¶ added in v0.6.0
func LoadInitialSections(config *ModuleConfig, r Reader) (m *Module, err error)
LoadInitialSections reads module header and all sections preceding code and data.
