LLVM backend for 6502
c385709d83
Also corrected the definition of the intrinsics for these instructions (the result register is also the first operand), and added intrinsics for bsel and bseli to clang (they already existed in the backend). These four operations are mostly equivalent to bsel, and bseli (the difference is which operand is tied to the result). As a result some of the tests changed as described below. bitwise.ll: - bsel.v test adapted so that the mask is unknown at compile-time. This stops it emitting bmnzi.b instead of the intended bsel.v. - The bseli.b test now tests the right thing. Namely the case when one of the values is an uimm8, rather than when the condition is a uimm8 (which is covered by bmnzi.b) compare.ll: - bsel.v tests now (correctly) emits bmnz.v instead of bsel.v because this is the same operation (see MSA.txt). i8.ll - CHECK-DAG-ized test. - bmzi.b test now (correctly) emits equivalent bmnzi.b with swapped operands because this is the same operation (see MSA.txt). - bseli.b still emits bseli.b though because the immediate makes it distinguishable from bmnzi.b. vec.ll: - CHECK-DAG-ized test. - bmz.v tests now (correctly) emits bmnz.v with swapped operands (see MSA.txt). - bsel.v tests now (correctly) emits bmnz.v with swapped operands (see MSA.txt). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193693 91177308-0d34-0410-b5e6-96231b3b80d8 |
