Hal Finkel 9ede5a39dd Make use of @llvm.assume from LazyValueInfo ... This change teaches LazyValueInfo to use the @llvm.assume intrinsic. Like with the known-bits change (r217342), this requires feeding a "context" instruction pointer through many functions. Aside from a little refactoring to reuse the logic that turns predicates into constant ranges in LVI, the only new code is that which can 'merge' the range from an assumption into that otherwise computed. There is also a small addition to JumpThreading so that it can have LVI use assumptions in the same block as the comparison feeding a conditional branch. With this patch, we can now simplify this as expected: int foo(int a) { __builtin_assume(a > 5); if (a > 3) { bar(); return 1; } return 0; } llvm-svn: 217345		2014-09-07 20:29:59 +00:00
