Functions ¶

func AddSymbolPrefixUnder ¶

func AddSymbolPrefixUnder(name string, isCpp bool) string

For mutiple os test,the nm output's symbol name is different.

func Do ¶

func Do(conf *Config) error

func GenSymbolTableData ¶

func GenSymbolTableData(commonSymbols []*llcppg.SymbolInfo) ([]byte, error)

func GenerateSymTable ¶

func GenerateSymTable(symbols []*nm.Symbol, headerInfos map[string]*SymbolInfo) ([]byte, error)

func GetCommonSymbols ¶

func GetCommonSymbols(dylibSymbols []*nm.Symbol, headerSymbols map[string]*SymbolInfo) []*llcppg.SymbolInfo

finds the intersection of symbols from the dynamic library's symbol table and the symbols parsed from header files. It returns a list of symbols that can be externally linked.

func GetIncludePaths ¶

func GetIncludePaths() []string

func GetLibPaths ¶

func GetLibPaths() []string

func ParseClangIncOutput ¶

func ParseClangIncOutput(output string) []string

func ParseDylibSymbols ¶

func ParseDylibSymbols(lib string) ([]*nm.Symbol, error)

ParseDylibSymbols parses symbols from dynamic libraries specified in the lib string. It handles multiple libraries (e.g., -L/opt/homebrew/lib -llua -lm) and returns symbols if at least one library is successfully parsed. Errors from inaccessible libraries (like standard libs) are logged as warnings.

Returns symbols and nil error if any symbols are found, or nil and error if none found.

func ParseHeaderFile ¶

func ParseHeaderFile(files []string, prefixes []string, cflags []string, symMap map[string]string, isCpp bool, isTemp bool) (map[string]*SymbolInfo, error)

func ParseLdOutput ¶

func ParseLdOutput(output string) []string

Note:this function is only use in this package The public function name is for llgo test

func SetDebug ¶

func SetDebug(flags dbgFlags)

Types ¶

type Collect ¶

type Collect struct {
	SymName    string             // symbol name
	GetSymInfo func() *SymbolInfo // get symbol info
}

type Config ¶

type Config struct {
	Conf *llcppg.Config
}

type SymbolInfo ¶

type SymbolInfo struct {
	GoName    string
	ProtoName string
}

type SymbolProcessor ¶

type SymbolProcessor struct {
	Files      []string
	Prefixes   []string
	SymbolMap  map[string]*SymbolInfo
	NameCounts map[string]int
	// custom symbol map like:
	// "sqlite3_finalize":".Close" -> method
	// "sqlite3_open":"Open" -> function
	CustomSymMap map[string]string
	// contains filtered or unexported fields
}

func NewSymbolProcessor ¶

func NewSymbolProcessor(Files []string, Prefixes []string, SymMap map[string]string) *SymbolProcessor

func (*SymbolProcessor) AddSuffix ¶

func (p *SymbolProcessor) AddSuffix(name string) string

func (*SymbolProcessor) GenMethodName ¶

func (p *SymbolProcessor) GenMethodName(class, name string, isDestructor bool, isPointer bool) string
