Currently, it seems that using the LLVM IR static translation backend
of PyPy gives higher performance.

Hi Manuel,
We've been suitably impressed by the results on the new llvm backend
during the sprint (well, or suitably un-impressed by both gcc and
clang's failure to reconstruct the SSA meaning of the C code).
The current issue seems to be debugging. It would be nice if gdb
presented at least

Hi,
I am missing some background information to follow what is being discussed
here, so...
What is the PyPy speed difference after using gcc versus llvm for the
compilation of the PyPy-c backend?
Would generating .ll instead of .c files really give any benefit?
More interesting would still
