class FileCheckPatternContext

Declaration

class FileCheckPatternContext { /* full declaration omitted */ };

Description

Class holding the Pattern global state, shared by all patterns: tables holding values of variables and whether they are defined or not at any given time in the matching process.

Declared at: llvm/lib/Support/FileCheckImpl.h:244

Method Overview

• public void clearLocalVars()
• public void createLineVariable()
• public llvm::Error defineCmdlineVariables(std::vector<std::string> & CmdlineDefines, llvm::SourceMgr & SM)
• public Expected<llvm::StringRef> getPatternVarValue(llvm::StringRef VarName)

Methods

¶void clearLocalVars()

Description

Undefines local variables (variables whose name does not start with a '$' sign), i.e. removes them from GlobalVariableTable and from GlobalNumericVariableTable and also clears the value of numeric variables.

Declared at: llvm/lib/Support/FileCheckImpl.h:297

¶void createLineVariable()

Description

Create @LINEpseudo variable. Value is set when pattern are being matched.

Declared at: llvm/lib/Support/FileCheckImpl.h:291

¶llvm::Error defineCmdlineVariables(
    std::vector<std::string>& CmdlineDefines,
    llvm::SourceMgr& SM)

Description

Defines string and numeric variables from definitions given on the command line, passed as a vector of [#]VAR=VAL strings in\p CmdlineDefines.

Declared at: llvm/lib/Support/FileCheckImpl.h:286

Parameters

std::vector<std::string>& CmdlineDefines

llvm::SourceMgr& SM

Returns

an error list containing diagnostics against\p SM for all definition parsing failures, if any, or Success otherwise.

¶Expected<llvm::StringRef> getPatternVarValue(
    llvm::StringRef VarName)

Declared at: llvm/lib/Support/FileCheckImpl.h:280

Parameters

llvm::StringRef VarName

Returns

the value of string variable \p VarName or an error if no such variable has been defined.
