Member Data Documentation

Context

FileCheckPatternContext* llvm::Substitution::Context

protected

Pointer to a class instance holding, among other things, the table with the values of live string variables at the start of any given CHECK line.

Used for substituting string variables with the text they were defined as. Expressions are linked to the numeric variables they use at parse time and directly access the value of the numeric variable to evaluate their value.

Definition at line 347 of file FileCheckImpl.h.

Referenced by llvm::StringSubstitution::getResult().

FromStr

StringRef llvm::Substitution::FromStr

protected

The string that needs to be substituted for something else.

For a string variable this is its name, otherwise this is the whole expression.

Definition at line 351 of file FileCheckImpl.h.

Referenced by getFromString(), and llvm::StringSubstitution::getResult().

InsertIdx

size_t llvm::Substitution::InsertIdx
