SgAsmRiscOperation Class Reference

Description

Static representation of instruction semantics.

Instruction semantics are not added to the AST by default since this would make it very, very large. Instead, ROSE has a non-traditional approach: instead of ROSE having C++ code to generate a data-centric representation of semantics (a tree like data structure similar to a syntax tree) and then users writing analyses on that data structure, ROSE's C++ code can be hooked into directly by users via C++ class derivation. If a user really wants a data-centric view they can either have ROSE create SgAsmRiscOperation nodes in the AST, or they can hook into ROSE's instruction semantics API and build whatever kind of data-centric representation that suites their need.

Member Enumeration Documentation

One enum per RISC operator.

The names are the same as the RISC operator. Note that some of these operators aren't normally part of the base set. For instance, "subtract" and comparison operations are usually implemented in terms of more basic operations like add_, invert, and equalToZero.

Enumerator
OP_add 

Two args + optional carry bit.

OP_addCarries 

Carries from a 3-arg add operation.

OP_readMemory 

Three or four args depending on whether segment reg is present.

OP_writeMemory 

Three or four args depending on whether segment reg is present.

OP_N_OPERATORS 

Number of operators in this enum.

Member Function Documentation

RiscOperator SgAsmRiscOperation::get_riscOperator ( ) const

Property: Low-level semantic operation.

This property is an enum constant that represents an operation in RiscOperators.

void SgAsmRiscOperation::set_riscOperator ( RiscOperator  )

Property: Low-level semantic operation.

This property is an enum constant that represents an operation in RiscOperators.

SgAsmExprListExp* SgAsmRiscOperation::get_operands ( ) const

Property: Operands for the low-level operation.

These are the operands used by the low-level operation. The actual list is stored in a separate SgAsmExprListExpr AST node instead of directly in this node due to limitations of ROSETTA.

void SgAsmRiscOperation::set_operands ( SgAsmExprListExp )

Property: Operands for the low-level operation.

These are the operands used by the low-level operation. The actual list is stored in a separate SgAsmExprListExpr AST node instead of directly in this node due to limitations of ROSETTA.
