[LLVMdev] LLVM projects: Change framework
Jakob,
What exactly can you describe in this change language? There is a
lot of research happening now on techniques to identify the best
sequence of optimizations for a particular program, or just the best
output form for the program. There are no really good
infrastructures for this kind of work, but we have been interested in
making LLVM useful for such work. (LLVM has been used

[LLVMdev] LLVM projects: Change framework
hi all,
I have used LLVM extensively over the last 2 years.
I have realized a so called change framework that based on the LLVM
framework.
Basically it is a framework that augments the JIT to understand
"changes", such that a mutator process can formulate changes in a change
language (inspired by DTrace's D), which is too compiled to LLVM and
sent to the application process.
