void emitInstrCountChangedRemark(
    llvm::Pass* P,
    llvm::Module& M,
    int64_t Delta,
    unsigned int CountBefore,
    StringMap<
        std::pair<unsigned int, unsigned int>>&
        FunctionToInstrCount,
    llvm::Function* F = nullptr)

Description

Emit a remark signifying that the number of IR instructions in the module changed.\p F is optionally passed by passes which run on Functions, and thus always know whether or not a non-empty function is available. \p FunctionToInstrCount maps the name of a \p Function to a pair. The first member of the pair is the IR count of the \p Function before running\p P, and the second member is the IR count of the \p Function after running \p P.

llvm::Pass* P
llvm::Module& M
int64_t Delta
unsigned int CountBefore
StringMap<std::pair<unsigned int, unsigned int>>& FunctionToInstrCount
llvm::Function* F = nullptr
