clang: clang::interp::Context Class Reference

Holds all information required to evaluate constexpr code in a module. More...

#include "/home/buildbot/as-worker-4/publish-doxygen-docs/llvm-project/clang/lib/AST/ByteCode/Context.h"

  Context (ASTContext &Ctx)   Initialises the constexpr VM.
    ~Context ()   Cleans up the constexpr VM.
  bool  isPotentialConstantExpr (State &Parent, const FunctionDecl *FnDecl)   Checks if a function is a potential constant expression.
  bool  evaluateAsRValue (State &Parent, const Expr *E, APValue &Result)   Evaluates a toplevel expression as an rvalue.
  bool  evaluate (State &Parent, const Expr *E, APValue &Result, ConstantExprKind Kind)   Like evaluateAsRvalue(), but does no implicit lvalue-to-rvalue conversion.
  bool  evaluateAsInitializer (State &Parent, const VarDecl *VD, APValue &Result)   Evaluates a toplevel initializer.
  ASTContext &  getASTContext () const   Returns the AST context.
  const LangOptions &  getLangOpts () const   Returns the language options.
  InterpStack &  getStack ()   Returns the interpreter stack.
  unsigned  getCharBit () const   Returns CHAR_BIT.
  const llvm::fltSemantics &  getFloatSemantics (QualType T) const   Return the floating-point semantics for T.
  uint32_t  getBitWidth (QualType T) const   Return the size of T in bits.
  std::optional< PrimType >  classify (QualType T) const   Classifies a type.
  std::optional< PrimType >  classify (const Expr *E) const   Classifies an expression.
  const CXXMethodDecl *  getOverridingFunction (const CXXRecordDecl *DynamicDecl, const CXXRecordDecl *StaticDecl, const CXXMethodDecl *InitialFunction) const   const Function *  getOrCreateFunction (const FunctionDecl *FD)   Program &  getProgram () const   Returns the program. This is only needed for unittests.
  unsigned  collectBaseOffset (const RecordDecl *BaseDecl, const RecordDecl *DerivedDecl) const   const Record *  getRecord (const RecordDecl *D) const   unsigned  getEvalID () const
