static bool Execute(ProcessInfo &PI, StringRef Program, ArrayRef< StringRef > Args, std::optional< ArrayRef< StringRef > > Env, ArrayRef< std::optional< StringRef > > Redirects, unsigned MemoryLimit, std::string *ErrMsg, BitVector *AffinityMask, bool DetachProcess)
ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.
StringRef - Represent a constant reference to a string, i.e.
static constexpr size_t npos
size_t find_first_of(char C, size_t From=0) const
Find the first character in the string that is C, or npos if not found.
This class implements an extremely fast bulk output stream that can only output to a stream.
LLVM_ABI void printArg(llvm::raw_ostream &OS, StringRef Arg, bool Quote)
Print a command argument, and optionally quote it.
Definition Program.cpp:81
LLVM_ABI bool commandLineFitsWithinSystemLimits(StringRef Program, ArrayRef< StringRef > Args)
Return true if the given arguments fit within system-specific argument length limits.
LLVM_ABI ProcessInfo ExecuteNoWait(StringRef Program, ArrayRef< StringRef > Args, std::optional< ArrayRef< StringRef > > Env, ArrayRef< std::optional< StringRef > > Redirects={}, unsigned MemoryLimit=0, std::string *ErrMsg=nullptr, bool *ExecutionFailed=nullptr, BitVector *AffinityMask=nullptr, bool DetachProcess=false)
Similar to ExecuteAndWait, but returns immediately.
Definition Program.cpp:57
LLVM_ABI int ExecuteAndWait(StringRef Program, ArrayRef< StringRef > Args, std::optional< ArrayRef< StringRef > > Env=std::nullopt, ArrayRef< std::optional< StringRef > > Redirects={}, unsigned SecondsToWait=0, unsigned MemoryLimit=0, std::string *ErrMsg=nullptr, bool *ExecutionFailed=nullptr, std::optional< ProcessStatistics > *ProcStat=nullptr, BitVector *AffinityMask=nullptr)
This function executes the program using the arguments provided.
Definition Program.cpp:32
This is an optimization pass for GlobalISel generic memory operations.
This struct encapsulates information about a process.
