...put directory And optionally, if we were to argue that dumping graphs could be the default over viewing: - Renaming the existing -view-dag-... options (listed at [1]) to -dump-dag-... I would like to hear your opinions on this. Kind regards, Roel [1] http://llvm.org/docs/CodeGenerator.html#selectiondag_process

...sors with very limited resources and highly respects energy saving. in which direction llvm team heads? you (chris) didn't mention the optimization code in #1 - #4, and i cannot find the optimization code in the step 2 and step 4 mentioned in: http://llvm.cs.uiuc.edu/docs/CodeGenerator.html#selectiondag_process i don't know if the optimization doesn't existing (a doc bug) or you just miss them? another question raises. unlike "coins" (http://www.coins-project.org/international/), there is only one high level ir (immediate representation) in the llvm. a low-level ir is lacked for low-lev...

...mersManual.html#DEBUG You can find some example debug code e.g. in method Select(SDNode *Node) in source file lib/Target/MSP430/MSP430ISelDAGToDAG.cpp http://llvm.org/releases/3.0/docs/ProgrammersManual.html#ViewGraph (and the -view… options in http://llvm.org/releases/3.0/docs/CodeGenerator.html#selectiondag_process) This takes some minimal effort to setup but is incredibly useful: Run llc with all -view… options on. This will get you a first idea on where the problem occurs. Then if you find the causing SelectionDAG pass, let's say your Select method in Z80IselDAGToDAG, then you can set a breakpoint there...

Noone is currently working on automating the pattern matching generator process yet. Before doing that, there are a few changes we want to make to the SelectionDAG interface. In particular, right now, the selection process basically works like this: #1.

i'd like to know what progress you guys have made (not on cvs?). i don't want to re-invent wheels, and the existing many code generator generators. i am evaluating many possbile code generation libraries. at present i give me preferrence to "Prop": http://www.cs.nyu.edu/leunga/www/prop.html and it's portable too. are there any other good library you could recommend?
