Function Documentation

◆ addIncludeLinkerOption()

static void addIncludeLinkerOption ( const ToolChain TC,
const llvm::opt::ArgList &  Args,
llvm::opt::ArgStringList &  CmdArgs,
StringRef  SymbolName 
)
static

◆ describeSanitizeArg()

std::string describeSanitizeArg ( const llvm::opt::Arg *  A,
SanitizerMask  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".

◆ getDefaultBlacklist()

static bool getDefaultBlacklist ( const Driver D,
SanitizerMask  Kinds,
std::string &  BLPath 
)
static

Definition at line 95 of file SanitizerArgs.cpp.

References clang::driver::Driver::ResourceDir.

◆ lastArgumentForMask()

std::string lastArgumentForMask ( const Driver D,
const llvm::opt::ArgList &  Args,
SanitizerMask  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".

◆ parseArgValues()

SanitizerMask parseArgValues ( const Driver D,
const llvm::opt::Arg *  A,
bool  DiagnoseErrors

◆ parseCoverageFeatures()

int parseCoverageFeatures ( const Driver D,
const llvm::opt::Arg *  A 
)
static

Parse -f(no-)?sanitize-coverage= flag values, diagnosing any invalid components.

Returns OR of members of CoverageFeature enumeration.
