Detailed Description

An opdis disassembler.

Note:

The visited_addr tree is NULL by default. Both opdis_disasm_cflow and opdis_disasm_bfd_cflow create this tree if visited_addr is NULL. This means that linear disassembly will not check if an address exists before invoking the display callback.

This is defined in dis-asm.h in the binutils distribution.

opdis_info_t::disassembler

libopcodes print_insn routine

Note:

This is defined in dis-asm.h in the binutils distribution.

opdis_info_t::visited_addr

Index of all VMAs that have been disassembled and displayed.

A tree of all instructions that have been disassembled. If this is non-NULL, the default handler will check if the VMA for the current instruction is in the tree. If not, the instruction is added to the tree and the handler returns 1 (i.e. instruction will be displayed). Otherwise, the handler returns 0 (do not display the instruction, and stop disassembly).

Note:

Use of the visited addresses tree will ensure that no duplicate instructions are emitted, but will noticably slow down disassembly.
