| /* decode_instructions -- dump a range of addresses as native instructions |
| This implements the protocol required by the HotSpot PrintAssembly option. |
| |
| The start_va, end_va is the virtual address the region of memory to |
| disasemble and buffer contains the instructions to decode, |
| Disassembling instructions in the current address space is done by |
| having start_va == buffer. |
| |
| The option string, if not empty, is interpreted by the disassembler implementation. |
| |
| The printf callback is 'fprintf' or any other workalike. |
| It is called as (*printf_callback)(printf_stream, "some format...", some, format, args). |
| |
| The event callback receives an event tag (a string) and an argument (a void*). |
| It is called as (*event_callback)(event_stream, "tag", arg). |
| |
| Events: |
| <insn pc='%p'> begin an instruction, at a given location |
| </insn pc='%d'> end an instruction, at a given location |
| <addr value='%p'/> emit the symbolic value of an address |
| |
| A tag format is one of three basic forms: "tag", "/tag", "tag/", |
| where tag is a simple identifier, signifying (as in XML) a element start, |
| element end, and standalone element. (To render as XML, add angle brackets.) |
