Actually, reading over all of this again, I realize I may have made the
wrong statement. The runtime regressions we see in julia are actually
regressions in how long LLVM itself takes to do the compilation (but since
it happens at run time in the JIT case, I think of it as a regression in
our running time). We have only noticed occasional regressions in the
performance of the generated code (which we are in the process of fixing).
Which kind of regression are you talking about, time taken by LLVM or time
taken by the LLVM-generated code?
