	[rvm-research] Follow specific bytecode through compilation by frederick.ryckbosch-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, I'm trying to measure some characteristics about linked datastructures using JikesRVM. I want to be able to find the assembler instructions generated for all getfield bytecodes. Is there a way to tag instructions generated for getfield bytecodes during compilation ? Basically I want to know if an instruction was generated for a getfield-bytecode or not, during assembly. Any ideas ? Thanks!

	Re: [rvm-research] Follow specific bytecode through compilation by frederick.ryckbosch-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, Perhaps my question is not clear enough. What I basically need is a map between bytecodes and assembler for the opt compiler. I've seen articles where people added this to JikesRVM. My question is: can anybody give me some pointers on how to do this ? I have very little compiler expierence so I don't know where to start. Thanks in advance !

	Re: [rvm-research] Follow specific bytecode through compilation by Eliot Moss :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Frederick -- I believe that in order to get the bytecode associated with each machine instruction you mostly have to enable appropriate verbose output from the Opt compiler -- so look into the flags that control such output. I'm sure someone else can clarify further :-) ....

If an IR instruction is tagged as being a GC point or a PEI, then an entry is generated in the opt compiler's machinecode maps that allows the runtime system to map from the machinecode instruction back to the source level bytecode. In theory, you could use this same mapping mechanism to get the maps you want by ensuring that the IR instructions that were generated from the bytecode of interest were tagged as needing machine code map entries. Take a look at OptCompiledMethod and OptMachineCodeMap. `We don't do it for all instructions because of (a) space overheads for the mapping info and (b) as the optimizer does various transformations it's not always totally clear what bytecode instruction should be associated with a given IR/machinecode instruction.` `--dave` ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Jikesrvm-researchers mailing list Jikesrvm-researchers@... https://lists.sourceforge.net/lists/listinfo/jikesrvm-researchers
