Member Enumeration Documentation

enum Rose::BinaryAnalysis::HotPatch::Record::Type

Type of patch record.

Enumerator
PATCH_REGISTER	Change the value of a register.
PATCH_NONE	Type for default-constructed records.

Definition at line 31 of file HotPatch.h.

enum Rose::BinaryAnalysis::HotPatch::Record::Behavior

Behavior when a record matches.

Enumerator
MATCH_CONTINUE	Try to match additional subsequent records.
MATCH_BREAK	Don't try to match more records after a match is found.

Constructor & Destructor Documentation

Rose::BinaryAnalysis::HotPatch::Record::Record ( )

inline

Construct a no-op record.

Definition at line 65 of file HotPatch.h.

Rose::BinaryAnalysis::HotPatch::Record::Record ( RegisterDescriptor  reg, const InstructionSemantics::BaseSemantics::SValuePtr &  oldValue, const InstructionSemantics::BaseSemantics::SValuePtr &  newValue, Behavior  behavior = MATCH_CONTINUE  )

inline

Construct a record that substitutes a register.

If reg is an empty (default constructed) register descriptor or if the oldValue is null then the returned record will never match any state. The newValue must be non-null.

Definition at line 72 of file HotPatch.h.

Member Function Documentation

Type Rose::BinaryAnalysis::HotPatch::Record::type ( ) const

inline

Property: Type of record.

The record type is read-only, set when the record was constructed.

Definition at line 81 of file HotPatch.h.

RegisterDescriptor Rose::BinaryAnalysis::HotPatch::Record::reg ( ) const

inline

Property: Register to be matched.

For PATCH_REGISTER records, this is the register that is to be examined and possibly changed. An empty (default constructed) register descriptor doesn't ever match anything.

Definition at line 91 of file HotPatch.h.

void Rose::BinaryAnalysis::HotPatch::Record::reg ( RegisterDescriptor  r )

inline

Property: Register to be matched.

For PATCH_REGISTER records, this is the register that is to be examined and possibly changed. An empty (default constructed) register descriptor doesn't ever match anything.

Definition at line 94 of file HotPatch.h.

InstructionSemantics::BaseSemantics::SValuePtr Rose::BinaryAnalysis::HotPatch::Record::oldValue ( ) const

inline

Property: Value to match.

This is the value that must be matched in order for this patch record to be applied. A null value never matches anything.

Definition at line 105 of file HotPatch.h.

void Rose::BinaryAnalysis::HotPatch::Record::oldValue ( const InstructionSemantics::BaseSemantics::SValuePtr &  v )

inline

Property: Value to match.

This is the value that must be matched in order for this patch record to be applied. A null value never matches anything.

Definition at line 108 of file HotPatch.h.

InstructionSemantics::BaseSemantics::SValuePtr Rose::BinaryAnalysis::HotPatch::Record::newValue ( ) const

inline

Property: Replacement value.

This is the value that will be substituted into the state if the hot patch record matches. The value must not be null.

Definition at line 119 of file HotPatch.h.

void Rose::BinaryAnalysis::HotPatch::Record::newValue ( const InstructionSemantics::BaseSemantics::SValuePtr &  v )

inline

Property: Replacement value.

This is the value that will be substituted into the state if the hot patch record matches. The value must not be null.

Definition at line 122 of file HotPatch.h.

Behavior Rose::BinaryAnalysis::HotPatch::Record::behavior ( ) const

inline

Property: Behavior after matching.

When a record matches, the behavior property determines if the hot patch mechanism continues to search for additional matching records, or stops trying to match.

Definition at line 133 of file HotPatch.h.

void Rose::BinaryAnalysis::HotPatch::Record::behavior ( Behavior  b )

inline

Property: Behavior after matching.

When a record matches, the behavior property determines if the hot patch mechanism continues to search for additional matching records, or stops trying to match.
