jrose@535 | 25 | /* decode_instructions -- dump a range of addresses as native instructions |
jrose@535 | 26 | This implements the protocol required by the HotSpot PrintAssembly option. |
jrose@535 | 27 | |
jrose@535 | 28 | The starting and ending addresses are within the current process's address space. |
jrose@535 | 29 | |
jrose@535 | 30 | The option string, if not empty, is interpreted by the disassembler implementation. |
jrose@535 | 31 | |
jrose@535 | 32 | The printf callback is 'fprintf' or any other workalike. |
jrose@535 | 33 | It is called as (*printf_callback)(printf_stream, "some format...", some, format, args). |
jrose@535 | 34 | |
jrose@535 | 35 | The event callback receives an event tag (a string) and an argument (a void*). |
jrose@535 | 36 | It is called as (*event_callback)(event_stream, "tag", arg). |
jrose@535 | 37 | |
jrose@535 | 38 | Events: |
jrose@535 | 39 | <insn pc='%p'> begin an instruction, at a given location |
jrose@535 | 40 | </insn pc='%d'> end an instruction, at a given location |
jrose@535 | 41 | <addr value='%p'/> emit the symbolic value of an address |
jrose@535 | 42 | |
jrose@535 | 43 | A tag format is one of three basic forms: "tag", "/tag", "tag/", |
jrose@535 | 44 | where tag is a simple identifier, signifying (as in XML) a element start, |
jrose@535 | 45 | element end, and standalone element. (To render as XML, add angle brackets.) |
