Enumeration Type Documentation

enum SanitizeKind

Represents a set of sanitizer kinds. It is also used to define: 1) set of sanitizers each sanitizer group expands into. 2) set of sanitizers sharing a specific property (e.g. all sanitizers with zero-base shadow).

Definition at line 38 of file SanitizerArgs.cpp.

enum SanitizeOrdinal

Assign ordinals to possible values of -fsanitize= flag. We use the ordinal values as bit positions within SanitizeKind.

Definition at line 27 of file SanitizerArgs.cpp.

Function Documentation

static void addAllOf ( clang::SanitizerSet &  Sanitizers,
unsigned  Kinds 
) [static]

Adds all sanitizers from Kinds to Sanitizers.

Definition at line 61 of file SanitizerArgs.cpp.

Referenced by clang::driver::SanitizerArgs::SanitizerArgs().

std::string describeSanitizeArg ( const llvm::opt::Arg *  A,
unsigned  Mask 
) [static]

Produce an argument string from argument A, which shows how it provides a value in Mask. For instance, the argument "-fsanitize=address,alignment" with mask NeedsUbsanRt would produce "-fsanitize=alignment".

unsigned expandGroups ( unsigned  Kinds) [static]

For each sanitizer group bit set in Kinds, set the bits for sanitizers this group enables.

static bool hasOneOf ( const clang::SanitizerSet &  Sanitizers,

Returns true if set of Sanitizers contain at least one sanitizer from Kinds.

std::string lastArgumentForMask ( const Driver &  D,
const llvm::opt::ArgList &  Args,
unsigned  Mask 
) [static]

Produce an argument string from ArgList Args, which shows how it provides some sanitizer kind from Mask. For example, the argument list "-fsanitize=thread,vptr -fsanitize=address" with mask NeedsUbsanRt would produce "-fsanitize=vptr".

bool parseArgument ( const Driver &  D,
const llvm::opt::Arg *  A,
unsigned &  Add,
unsigned &  Remove,
bool  DiagnoseErrors 
) [static]

Parse a single flag of the form -f[no]sanitize=. Sets the masks defining required change of the set of sanitizers. Returns true if the flag was parsed successfully.

unsigned parseArgValues ( const Driver &  D,

Parse a -fsanitize= or -fno-sanitize= argument's values, diagnosing any invalid components. Returns OR of members of SanitizeKind enumeration.

unsigned parseValue ( const char *  Value) [static]

Parse a single value from a -fsanitize= or -fno-sanitize= value list. Returns a member of the SanitizeKind enumeration, or 0 if Value is not known.
