My own codegen is 2.5x slower than llc?
My back-end code generator uses LLVM 5.0.1 to optimize and generate code
for x86_64.
If I run it on a given sample of IR, it takes almost 5 minutes to generate
object code. 95%+ of this time is spent in MergeConsecutiveStores(). (One
function has a basic block with 14000 instructions, which is a pathological
case for MergeConsecutiveStores.)
If, instead, I dump out the LLVM IR, and manually
