getElementNumber()

int VectorMemberExpr::getElementNumber ( ) const

virtual

Implements MemberExpr.

Definition at line 4802 of file expr.cpp.

References Error(), MemberExpr::identifier, and lIdentifierToVectorElement().

getElementType()

const Type * VectorMemberExpr::getElementType ( ) const

virtual

Implements MemberExpr.

Definition at line 4809 of file expr.cpp.

References memberType.

GetLValue()

llvm::Value * VectorMemberExpr::GetLValue ( FunctionEmitContext *  ctx ) const

virtual

For expressions that can provide an lvalue (e.g. array indexing), this function should emit IR that computes the expression's lvalue and returns the corresponding llvm::Value. Expressions that can't provide an lvalue should leave this unimplemented; the default implementation returns NULL.

Reimplemented from Expr.

Definition at line 4689 of file expr.cpp.

References MemberExpr::GetLValue(), and MemberExpr::identifier.

GetLValueType()

const Type * VectorMemberExpr::GetLValueType ( ) const

virtual

Returns the type of the value returned by GetLValueType(); this should be a pointer type of some sort (uniform or varying).

Reimplemented from Expr.

Definition at line 4697 of file expr.cpp.

Referenced by GetType().

GetType()

const Type * VectorMemberExpr::GetType ( ) const

virtual

Returns the Type of the expression.

Implements Expr.

Definition at line 4663 of file expr.cpp.

References exprVectorType, Type::GetAsUniformType(), Type::GetAsVaryingType(), VectorType::GetElementType(), GetLValueType(), MemberExpr::identifier, Type::IsUniformType(), Type::IsVaryingType(), memberType, and MemberExpr::type.

GetValue()

llvm::Value * VectorMemberExpr::GetValue ( FunctionEmitContext *  ctx ) const

virtual

This is the main method for Expr implementations to implement. It should call methods in the FunctionEmitContext to emit LLVM IR instructions to the current basic block in order to generate an llvm::Value that represents the expression's value.

Implements Expr.
