[LLVMdev] Local common subexpression elimination

[Nicolas Capens]

Hi all,

 

Is there any existing pass that performs fast local common subexpression
elimination?

 

The reason I'm asking is because global common subexpression elimination
(GVN or GVN-PRE) is too slow for my JIT purposes, but I see lots of value in
local CSE.

 

Thanks,

 

Nicolas
