LLVM backend for 6502

This commit introduces a canonical representation for the formulae. Basically, as soon as a formula has more that one base register, the scaled register field is used for one of them. The register put into the scaled register is preferably a loop variant. The commit refactors how the formulae are built in order to produce such representation. This yields a more accurate, but still perfectible, cost model. <rdar://problem/16731508> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209230 91177308-0d34-0410-b5e6-96231b3b80d8 |
