Custom Instruction Cost Model to LLVM RISC-V Backend
Hi,
I’m working on a RISC-V architecture that has instruction costs different
from those in the default cost model. Is there an out-of-source way to
provide llc with custom cost model? Or, does this need a change in LLVM
backend?
Also, the cost model is not totally static. For example, loads from
0x1000-0x1ffc take 1 cycle, whereas loads from address > 0x80000000, take
10-100 cycles. Is it
