Function Documentation

Sawyer::Optional<rose_addr_t> Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchJmpConst ( const Partitioner ,

Matches "JMP constant".

Returns the constant if matched, nothing otherwise.

bool Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchLeaCxMemBpConst ( const Partitioner ,

Matches "LEA ECX, [EBP + constant]" or variant.

bool Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchJmpMem ( const Partitioner ,

Matches "JMP [address]" or variant.

bool Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchMovBpSp ( const Partitioner ,

Matches "MOV EBP, ESP" or variant.

bool Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchMovDiDi ( const Partitioner ,

Matches "MOV EDI, EDI" or variant.

bool Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchPushBp ( const Partitioner ,

Matches "PUSH EBP" or variant.

bool Rose::BinaryAnalysis::Partitioner2::ModulesX86::matchPushSi ( const Partitioner ,

Matches "PUSH SI" or variant.

std::vector<rose_addr_t> Rose::BinaryAnalysis::Partitioner2::ModulesX86::scanCodeAddressTable ( const Partitioner ,
AddressInterval tableLimits,
const AddressInterval targetLimits,
size_t  tableEntrySize 

Reads a table of code addresses.

Reads a table that starts at the lower limit of tableLimits and does not extend past the upper limit. Each entry in the table is an instruction address of tableEntrySize bytes and the entry must exist in read-only memory. The address stored in the entry must be within the targetLimits interval and must be an address that is mapped with execute permission. As many entries as possible are read into the return vector. Upon return, the tableLimits is adjusted to indicate the actual location of the table.

Sawyer::Optional<rose_addr_t> Rose::BinaryAnalysis::Partitioner2::ModulesX86::findTableBase ( SgAsmExpression )

Try to match a base+offset expression.

Matches expressions like:

  • base + register
  • base + register * size
  • [ base + register ]
  • [ base + register * size ]

Returns the numeric value of base or nothing if the expression is not a recognized form.
