[LLVMdev] Very slow performance of lli on x86
Hi all,
LLVM is built without debug enabled. Also i am not forcing lli to use
interpreter mode. so i dont think the reason is not because of debug build
or interpreter mode.
*step 1: *
compiled the 3 files (generic_replica.c ,xacc.c and dacc.c) with clang-cc to
llvm bytecode files using -emit-llvm-bc and (-O0/-O3) options
*step 2:*
bytecode obtained from step 1 (generic_replica.bc, xacc.bc and dacc.bc) is
passed to opt tool using (-O0/-O3) options
*step 3:*
optimized bytecode obtained from step 2 (generic_replica.opt...

He is probably using the interpreter on a debug build.
